Inhalation: Get into fresh air promptly, loosen tight clothing, offer water, see physician if coughing, shortness of breath, or irritation continues
Skin Contact: Wash area thoroughly with soap and cool water, remove contaminated clothing, rinse under water for at least 15 minutes, medical attention for persistent rash or irritation
Eye Contact: Flush eyes gently yet thoroughly with running water for at least 10 minutes, keeping eyelids open, contact medical personnel if irritation persists
Ingestion: Do not induce vomiting, rinse out mouth thoroughly, drink water if not at risk of choking, get medical evaluation swiftly, provide MSDS to emergency physicians
General Instructions: Seek medical help for any persistent symptoms, keep packaging and substance for identification
Flammable Properties: May burn with exposure to high heat; produces irritating smoke and fumes
Suitable Extinguishing Agents: Dry powder, carbon dioxide, foam, water spray for large fires—avoid water jets that can spread powdered substance
Specific Hazards: Decomposition can release carbon oxides and unknown toxic gases
Protective Equipment: Firefighters should use full protective equipment and self-contained breathing apparatus
Instructions: Prevent contaminated run-off from entering drains, contain with sand or dirt, douse small flames quickly before product disperses
Personal Precautions: Wear gloves, safety goggles, mask/respirator in area, avoid raising dust, ventilate space, prevent unauthorized access
Spill Cleanup: Pick up with inert absorbent, such as sand or vermiculite, using non-sparking tools, place in sealable, marked waste containers
Disposal Method: Dispose of according to suitable laws for pharmaceutical or chemical waste
Environmental Precautions: Prevent substance entry to water, drains, or soil, rapid action required for accidental spill beside waterways
Decontamination: Wash spill site with detergent, ventilate indoor location, neutralize with diluted bleach if approved by local safety office
Handling Details: Wear protective gear; keep hands away from eyes and mouth, avoid direct touch, don’t eat or drink during use
Storage Requirements: Store tightly sealed in original container, cool and dry location, keep away from light, moisture, and incompatible substances like strong oxidizers
Separation: Store away from food, drink, and animal feed; maintain records of transfers to meet legal requirements
Shelf Life: Check product batch data, refrigerate or freeze if recommended by supplier, prevent temperature swings to avoid degradation, observe for discoloration or unusual odor before use
Handling Precautions: Staff must be trained in hormone-related risks, don’t permit access to workplace by children, pregnant, or breastfeeding individuals
Engineering Controls: Use local exhaust ventilation in processing areas, install HEPA filtration for dust
Personal Protective Equipment: Nitrile gloves, chemical splash goggles, lab coat, suitable mask/respirator for airborne powder, use eye wash and emergency shower stations
Hygiene Measures: Remove and clean PPE after use, wash hands thoroughly before breaks, avoid wearing contaminated clothing beyond the workplace
Occupational Limits: No established OSHA or ACGIH exposure limits for this specific compound—keep exposure as low as reasonably possible
Environmental Monitoring: Routine checks recommended during repeated or large-scale handling
Appearance: Fine white to off-white crystalline powder
Odor: None or faint/neutral
Molecular Weight: 290.45 g/mol
Melting Point: 175–180°C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Low in water, soluble in ethanol, methanol, chloroform
Vapor Pressure: Negligible under normal temperature
Density: About 1.13 g/cm³
pH: Not available in solid form
Storage Stability: Stable at room temperature if dry and sealed
Chemical Stability: Remains stable in original unopened packaging, away from sunlight or oxidizing materials
Possible Reactions: Will react vigorously with oxidizing agents, acids may degrade
Decomposition Products: Burns or decomposes into carbon monoxide, carbon dioxide, unknown toxic compounds
Incompatible Materials: Do not contact with peroxides, acids, or strong bases
Polymerization: Not anticipated under normal conditions; avoid high heat, strong acids to prevent runaway reactions
Acute Effects: Data scarce for acute lethal dose in humans or animals; minor symptoms include headache, dizziness, stomach upset
Chronic Effects: Extended exposure can mess with human hormone balance, potential for menstrual disturbance, decreased fertility, or developmental effects, especially in children or pregnant persons
Irritation: May cause redness, itching, or sensitivity with repeated skin or eye exposure
Carcinogenicity: Not listed as carcinogenic by NTP, IARC, or OSHA based on current classification
Exposure Routes: Most concern for ingestion or inhalation, less for intact skin
Aquatic Toxicity: Not well characterized, but synthetic hormones threaten aquatic life, especially development of fish and amphibians when even minute amounts leak
Persistence: Likely to break down slowly in nature, particularly in cold or low-oxygen conditions
Mobility: Strong adsorption to soil, but can move into waterways with sediment
Bioaccumulation: May concentrate in some animals due to lipophilicity
Removal: Standard water treatment methods rarely remove hormones completely; incineration preferred for bulk disposal to prevent ecosystem contact
Waste Handling: Place powdered or liquid waste in sealed containers, mark as hazardous or pharmaceutical, arrange disposal via qualified chemical or pharma waste handler
Contaminated Packaging: Triple-rinse then destroy or consign to hazardous waste
Incineration: Most effective for large volume or expired batch; avoid landfill or municipal waste stream
Legal Status: Many areas regulate disposal due to environmental and health risks; document all waste shipments for legal compliance
UN Number: Not classified as hazardous for ground or air shipping, unless formulated with dangerous substances
Shipping Name: 19-Norandrostenediol, no additional handling labelling unless mixed
Transport Hazard Class: Not designated by US DOT, TDG, ADR, IMDG, or IATA
Packing Group: No assignment for pure substance
Special Precautions: Package to prevent spills, protect from rough handling, temperature swings, keep shipping documents with load, declare accurately if co-mingled with other substances
USA: Not scheduled under federal hazardous material codes, but classified as a controlled substance regulated by DEA due to status as anabolic steroid precursor
EU: Handling, sale, and disposal often falls under REACH and pharmaceutical laws; consult ECHA database for updates
Other Jurisdictions: Some countries require license or specific reporting for possession, use, or disposal, especially in medical or sports supplement fields; verify regularly
Worker Protection: Regulations may stipulate training, medical surveillance, and record keeping
