Safety Data Sheet / MSDS — U-510
DCL0016 · Updated 16 October 2026
Preliminary online safety information. A product-specific issued SDS is not available in the supplied records.
1. Identification
| Parameter | Information |
|---|---|
| Product identifier | U-510, DCL0016 |
| Recommended use | Laboratory research reagent for lipid nanoparticle formulation studies. Not for human or veterinary use. |
| Supplier contact | DC Chemicals · sales@dcchemicals.com · www.dcchemicals.com |
| Responsible-party details | The full responsible-party address and telephone must be provided on the issued SDS. |
| Emergency contact | No verified product-specific emergency number is available in this record. In an emergency, contact local emergency services or the relevant poison information service; the sales mailbox is not an emergency service. |
2. Hazard identification
A verified hazard assessment for neat U-510 is not available in the supplied records. GHS hazard class, signal word, pictograms and hazard statements have not been assigned here. Missing information must not be interpreted as evidence that the product is harmless or non-hazardous.
Avoid breathing dust, aerosol or mist and avoid skin, eye and mouth contact. Handle as a research chemical with incompletely characterized hazards. Solvents used to prepare stock solutions introduce additional hazards that must be assessed separately.
3. Composition / ingredient information
| Parameter | Information |
|---|---|
| Substance | U-510; formula C39H79NO6; MW 658.06 g/mol |
| Identifier | Catalog DCL0016; CAS number not available |
| Catalog purity specification | >95% by ELSD-HPLC; not a measured result for an identified batch |
| Impurities / residual solvents | Batch-specific identities and levels are not available in this record. Request analytical documentation. |
4. First-aid measures
Eyes: Rinse immediately with plenty of water, remove contact lenses if easy to do, and continue rinsing. Seek medical advice after significant exposure or if symptoms persist.
Skin: Remove contaminated clothing and wash thoroughly with soap and water. Seek medical advice for irritation or other symptoms.
Inhalation: Move to fresh air without exposing the rescuer. Obtain urgent medical help for breathing difficulty.
Ingestion: Rinse the mouth. Do not induce vomiting unless directed by a medical professional. Seek medical advice and show the product label. Do not give anything by mouth to an unconscious person.
Specific acute/delayed symptoms and a product-specific antidote are not established in the available record.
5. Fire-fighting measures
Use extinguishing media appropriate to the surrounding fire; trained responders should choose the response. Product-specific flash point, flammability and extinguishing-media incompatibilities have not been established. Combustion of this carbon- and nitrogen-containing material may generate hazardous fumes. Firefighters should use suitable protective equipment and self-contained breathing apparatus.
6. Accidental release measures
Restrict access, ventilate the area and avoid aerosol or dust formation. Wear suitable protective equipment. Prevent release to drains and waterways. Collect recoverable material or absorb a solution spill using compatible inert material, then place in a labeled closed waste container. Follow the solvent-specific spill procedure for solutions; seek trained assistance for large or uncontrolled releases.
7. Handling and storage
Use in a suitably controlled laboratory with local exhaust ventilation as needed. Keep containers closed, avoid contact, and wash hands after handling. Do not eat or drink in the work area. Store the original product at −20 °C according to the product label, protected from moisture and unnecessary heat. Keep separate from strong oxidizing agents as a general precaution. Solution storage and compatibility require separate evaluation.
8. Exposure controls / personal protection
No product-specific occupational exposure limit is available in this record. Minimize exposure through enclosure or local exhaust ventilation. Wear chemical splash eye protection, a laboratory coat and gloves selected for the material, solvent and duration of contact. A laboratory exposure assessment must determine whether additional respiratory protection is needed; any respirator use must follow the applicable workplace program.
9. Physical and chemical properties
| Parameter | Information |
|---|---|
| Molecular formula / molecular weight | C39H79NO6 / 658.06 g/mol |
| Physical state, color, odor | Batch-specific appearance and odor information not supplied |
| Solubility | Ethanol is used for the lipid phase in the cited formulation study. No validated quantitative solubility limit is available. |
| pH / melting point / boiling point | No applicable measured data available |
| Flash point / flammability / explosion limits | No applicable measured data available |
| Auto-ignition / decomposition temperature | No applicable measured data available |
| Vapor pressure / density / viscosity | No applicable measured data available |
| Partition coefficient / particle characteristics | No applicable measured data available. Formulated-LNP particle size is not a property of neat U-510. |
10. Stability and reactivity
Product-specific reactivity, hazardous-reaction potential and decomposition conditions have not been fully characterized in the available records. Avoid unnecessary heat and strong oxidizing conditions. Hazardous fumes may arise during combustion or decomposition. Catalog storage guidance does not establish chemical compatibility or all foreseeable reaction hazards.
11. Toxicological information
No validated acute oral, dermal or inhalation toxicity values for neat U-510 are available here. Skin/eye irritation, sensitization, mutagenicity, carcinogenicity, reproductive toxicity, target-organ toxicity and aspiration hazards have not been resolved for this record. Absence of data does not establish absence of risk.
Published tolerability observations concern specific RNA-loaded LNPs in animal experiments. They do not establish the occupational safety classification of the neat lipid or human safety.
12. Ecological information
Measured ecotoxicity, environmental persistence, bioaccumulation and soil-mobility data are not available. Avoid environmental release; do not infer environmental safety from structural features or biological formulation studies.
13. Disposal considerations
Collect unused material, contaminated absorbents and packaging as laboratory chemical waste. Use an authorized waste-disposal service and follow applicable local requirements. Do not pour material or stock solutions into drains. Consider the solvent and any other constituents when selecting the waste stream.
14. Transport information
UN number, proper shipping name, transport hazard class, packing group and environmental transport status have not been verified. No “not regulated” classification is asserted. Obtain the issued SDS and shipment-specific classification from DC Chemicals before arranging transport; a solution may differ from the neat material.
15. Regulatory information
Product-specific chemical-inventory status and jurisdiction-specific classification have not been verified in this record. Research-use labeling does not by itself establish an exemption from chemical, workplace or transport requirements.
16. Other information
Prepared 16 October 2026 as an online preliminary safety reference. Identity and purity specification are from the DCL0016 product record; ethanol formulation use is supported by the cited publication. General laboratory precautions are not product-specific toxicology test results.
The organizational headings follow the OSHA SDS information framework; this reference does not claim compliance or replace an issued SDS.
