2Hazard(s) identification
Classification of the substance
Not classified as hazardous under OSHA HCS 2012 (29 CFR 1910.1200) or UN GHS Rev. 7.
Label elements
No pictogram, signal word, hazard statement or precautionary statement is required. Recommended precautions: wear gloves, a laboratory coat and eye protection; avoid generating dust or aerosols; wash hands after handling; do not eat, drink or smoke in the laboratory.
Hazards not otherwise classified / other hazards
- Pharmacologically active material. Accidental injection, ingestion or absorption may produce systemic effects consistent with the compound's mechanism of action; see Section 11.
- Finely divided organic powder may form combustible dust concentrations in air if dispersed in bulk (not expected at laboratory scale).
3Composition / information on ingredients
Crystalline or amorphous powder in a sealed glass vial.
| Ingredient | CAS No. | Formula | Concentration | Quantity | Ingredient classification |
|---|---|---|---|---|---|
| L-Carnitine Levocarnitine (inner salt); small molecule, not a peptide | 541-15-1 | C7H15NO3 | ≥ 95% (dry basis, as supplied) | 500 mg per vial | not classified |
Peptides are supplied as the acetate or trifluoroacetate salt unless stated otherwise; the counter-ion and residual water make up the balance of a lyophilized product. Concentration limits used for mixture classification follow OSHA HCS 2012 Appendix A.
4First-aid measures
| Inhalation | Move the person to fresh air and keep comfortable for breathing. If breathing is difficult or symptoms persist, call a POISON CENTER or doctor. |
|---|---|
| Skin contact | Take off contaminated clothing. Wash the skin with plenty of soap and water. If irritation or a rash develops, get medical advice. |
| Eye contact | Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do; continue rinsing. If eye irritation persists, get medical advice. |
| Ingestion | Rinse mouth. Do not induce vomiting. Call a POISON CENTER or doctor if you feel unwell. |
| Most important symptoms and effects | No specific symptoms are known. Pharmacologically active material: systemic effects consistent with its mechanism of action are possible after accidental injection, ingestion or absorption. |
| Indication of immediate medical attention | Treat symptomatically. Show this safety data sheet to the attending physician. No specific antidote is known. |
5Fire-fighting measures
| Suitable extinguishing media | Water spray, carbon dioxide, dry chemical or alcohol-resistant foam. Use measures appropriate to the surrounding fire. |
|---|---|
| Unsuitable extinguishing media | None known. Do not use a high-pressure water jet on powders (dust dispersion). |
| Specific hazards | Combustible organic solid; finely divided powder may form dust clouds. Thermal decomposition may release carbon monoxide, carbon dioxide and nitrogen oxides. |
| Protective equipment for fire-fighters | Self-contained breathing apparatus and full protective clothing. Prevent run-off from entering drains. |
6Accidental release measures
| Personal precautions | Wear the protective equipment in Section 8. Keep unprotected people away. Avoid dust formation and inhalation of dust. |
|---|---|
| Environmental precautions | Do not allow material to reach drains, surface water or soil. Quantities supplied are small; collect for disposal. |
| Methods for cleaning up | Avoid dust formation. Sweep or wipe up (dampened), place in a sealed container for disposal and clean the area with water. Decontaminate surfaces with 70% alcohol or detergent and water. |
7Handling and storage
| Precautions for safe handling | Avoid generating or inhaling dust; weigh inside a ventilated enclosure. Hygroscopic materials should be weighed quickly and the vial resealed. Wash hands after handling. Do not eat, drink or smoke in the handling area. |
|---|---|
| Conditions for safe storage | Store sealed, cool and dry, protected from light. See Section 9 for the storage temperature. Keep the container tightly closed and labelled, out of reach of unauthorised persons. |
| Storage temperature | Sealed, cool and dry (2–8 °C recommended), protected from light and moisture |
| Incompatible materials | Strong oxidising agents, strong acids and bases. |
8Exposure controls / personal protection
| Occupational exposure limits | No occupational exposure limits (OSHA PEL, ACGIH TLV, NIOSH REL) have been established for any ingredient. |
|---|---|
| Engineering controls | Good general laboratory ventilation. Weigh or manipulate dry powder in a ventilated enclosure (powder hood, biosafety cabinet or fume hood). An eyewash station should be available. |
| Eye / face protection | Safety glasses with side shields (ANSI Z87.1 / EN 166). |
| Skin protection | Nitrile gloves (inspect before use; change after contamination) and a laboratory coat. |
| Respiratory protection | Not normally required with the engineering controls above. Where dust cannot be controlled, use a NIOSH-approved N95 (or P2) particulate respirator. |
| Hygiene measures | Wash hands after handling and before breaks. Remove contaminated clothing. Do not pipette by mouth. |

|---|---|
| Classification method | Substance classification adopted from the supplier safety data sheets listed below, with the PrymaLab policy adjustments stated in Section 11. Policy: Cayman Chemical is the primary reference for research peptides and novel small molecules and Sigma-Aldrich/Merck for commodity chemicals; a more conservative manufacturer or ECHA classification is adopted where internally consistent; SARMs, GLP-1 receptor agonists, GnRH analogues and gonadotropins carry reproductive-toxicity classifications by expert judgement. |
