Supplier Information: [Insert local supplier details]
Emergency Contact: [Insert emergency number specific to supplier or region]
Classification: Not regulated as a hazardous material under GHS criteria
Physical Hazards: May form combustible dust concentrations in the air
Health Hazards: Prolonged or repeated contact can result in mild skin irritation; eye exposure can lead to discomfort. Ingestion and inhalation of large quantities might cause headache or mild hormonal effects.
Environmental Hazards: Not considered acutely hazardous, but large spills can disrupt local wastewater systems.
Label Elements: No specific pictograms required, but good lab practice prefers a general warning label
Component: Androsterone
Concentration: >98%
Impurities: Minor steroidal contaminants (less than 2%), not considered hazardous at this concentration
Additives: None
Molecular Weight: 290.44 g/mol
Eye Contact: Flush with clean water for at least 15 minutes. Remove contact lenses. Seek medical attention if irritation continues.
Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing and wash before reuse. Monitor for rash or irritation.
Inhalation: Move into fresh air. Allow rest and monitor for respiratory symptoms. If breathing becomes difficult, seek immediate medical attention.
Ingestion: Rinse mouth. Drink water to dilute material in the stomach. Do not induce vomiting. Medical evaluation recommended if more than trace amounts are swallowed or if symptoms develop.
Advice for Doctor: Symptomatic treatment; no specific antidote known.
Suitable Extinguishing Media: Use water spray, CO2, dry chemical, or foam. Pick the medium suitable for the surrounding fire.
Specific Hazards: Combustion produces CO, CO2, and potentially irritating organic vapors.
Special Firefighting Procedures: Firefighters should wear self-contained breathing apparatus and full protective gear. Avoid inhalation of smoke or combustion products.
Other Information: Avoid dust formation; fine particles increase fire risk.
Personal Precautions: Use personal protective equipment; avoid breathing dust and contact with skin or eyes.
Environmental Precautions: Prevent spilled material from entering drains, sewers, or natural waterways.
Cleanup Methods: Collect solid material by gently sweeping or vacuuming. Place material in a sealed container for disposal. Rinse spill area with water and mild detergent.
Other Notes: Dispose of collected material following local regulations.
Handling: Minimize dust generation. Work under a ventilated hood if possible. Keep away from sources of ignition. Avoid skin and eye contact. Use designated lab space.
Storage: Store in a tightly closed container in a cool, dry place. Keep away from direct sunlight, incompatibles such as strong acids, bases, and oxidizing agents. Store at room temperature or as instructed by the supplier.
Hygiene Practices: Wash hands after handling. Maintain general laboratory hygiene. Avoid eating, drinking, or smoking in work areas.
Fire Prevention: Store away from flammable materials.
Exposure Limit: Not established by OSHA, NIOSH, or ACGIH.
Engineering Controls: Laboratory fume hood or local exhaust recommended. Use closed handling systems, if available.
Personal Protective Equipment: Safety goggles, laboratory coat, chemical-resistant gloves (nitrile or latex), and, if dust is possible, N95 dust mask or equivalent.
Hygiene Measures: No food or drink near workplace. Wash hands before breaks and after finishing work.
Environmental Controls: Ventilation to avoid accumulation of airborne dust.
Appearance: White to off-white crystalline powder
Odor: Nearly odorless
pH: Not applicable (insoluble in water)
Boiling Point: Decomposes before boiling
Melting Point: 175–178°C
Solubility: Soluble in ethanol, chloroform, ether; insoluble in water
Relative Density: 1.12 (estimated)
Vapor Pressure: Negligible at room temperature
Flash Point: Data not available
Partition Coefficient (log Pow): 2.98
Auto-ignition Temperature: Not determined
Explosive Properties: Not explosive, but dust may pose risk if airborne in high concentrations
Viscosity: Not applicable
Chemical Stability: Stable at normal storage temperatures and conditions.
Reactivity: No hazardous reactions under normal handling.
Conditions to Avoid: Heat, open flame, generation of dust
Incompatible Materials: Strong oxidizing agents, acids, bases
Decomposition Products: Thermal decomposition releases CO, CO2, and potentially irritating organic fumes
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Acute Effects: May cause mild skin or eye irritation. Inhalation of dust might result in mild respiratory discomfort. Large-dose ingestion might lead to hormonal effects (very unlikely under typical lab conditions).
Chronic Effects: No chronic exposure studies available on humans; animal data suggest low toxicity at reasonable exposure levels.
Carcinogenicity: Not listed by IARC, NTP, OSHA as a carcinogen.
Sensitization: No data supporting skin sensitization.
Target Organ Effects: No specific target organ effects documented.
LD50/LC50: Not established.
Environmental Fate: Limited data suggest low mobility in soil and slow biodegradation rates.
Aquatic Toxicity: No specific data, but steroid hormones can disrupt aquatic species at higher concentrations. Trace environmental releases unlikely to cause significant impact.
Persistence and Degradability: May persist if released into water or soil due to limited water solubility and slow breakdown.
Bioaccumulation: Probable low due to weak solubility in water; not enough ecological data for higher organisms.
Other Adverse Effects: Excessive discharge should be avoided to prevent potential disruption to water treatment processes.
Waste Handling: Collect material in a sealed, labeled container.
Disposal Method: Dispose of through an approved chemical waste facility. Follow local and national regulations for disposal of steroidal compounds.
Do Not: Release into drains, surface water, or soil.
Contaminated Packaging: Triple rinse and dispose of similarly to unused product or via certified waste management services.
Additional Suggestions: Always handle and dispose of experimental waste in line with institutional policy and environmental standards.
UN Number: Not classified as dangerous goods for transport.
Proper Shipping Name: Not regulated.
Transport Hazard Class: Not applicable.
Packing Group: Not applicable.
Environmental Hazards: Not a marine pollutant.
Special Precautions for User: Keep in tightly sealed, labeled container; prevent rough handling to avoid dust cloud.
Labelling Requirements: Not classified as hazardous by major regulatory agencies (OSHA, GHS).
SARA Title III: Not a reportable substance.
TSCA Inventory: Listed.
REACH Status: Exempt or not listed; check current local guidance.
WHMIS Classification (Canada): Not controlled.
Other Regulatory Notes: Follow general laboratory chemical safety rules. Countries may have additional restrictions or reporting requirements based on use in pharmaceuticals or supplements.
