Inhalation: Move patient to fresh air. Seek medical advice if symptoms persist; monitor for cough or trouble breathing
Skin Contact: Remove contaminated clothing, wash skin with copious water and mild soap. See a doctor if irritation or rash develops
Eye Contact: Rinse eyes gently with clean water for several minutes, remove contact lenses if present, continue rinsing, seek medical attention
Ingestion: Rinse mouth, do not induce vomiting. Get medical attention promptly and give medical team the product information
Acute Effects: May include respiratory discomfort, headache, nausea; prolonged exposure may affect hormone balance
Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide, water spray for larger fires
Unsuitable Media: Avoid strong water jets that may spread chemical
Specific Hazards: Combustible solid; May emit toxic fumes (carbon monoxide, carbon dioxide) if burned
Protective Equipment: Firefighters need full protective gear, self-contained breathing apparatus
Precautions: Avoid breathing combustion products, isolate area if possible
Personal Precautions: Use gloves, lab coat, respirator if dust is present, safety eye protection; evacuate non-essential staff
Environmental Precautions: Block entry to drains or waterways, prevent dispersal of dust and fumes
Spill Cleanup Methods: If powder, use damp disposable towels or HEPA vacuum; avoid sweeping dry material
Waste Disposal: Place contaminated materials in sealed, labeled containers for chemical waste disposal
Handling Precautions: Work in ventilated space, avoid generating dust, wear proper protective gear, practice strict hygiene, keep containers tightly closed when not in use
Storage Requirements: Store in cool, dry, well-ventilated area below 25°C; keep away from light and sources of ignition; use child-resistant containers in research labs
Incompatible Materials: Strong oxidizers, acids, and bases; avoid storage next to foodstuffs or animal feeds
Special Considerations: Regularly check storage conditions; use secondary containment for larger quantities
Engineering Controls: Local exhaust, glove box, or fume hood recommended
Respiratory Protection: Use dust respirator (N95 minimum); do not rely on open-bench work
Hand Protection: Disposable nitrile or latex gloves, change gloves frequently
Eye Protection: Chemical splash goggles or safety glasses
Skin Protection: Lab coat, closed shoes, optionally disposable sleeve covers
Hygiene Measures: Wash hands after handling; do not eat, drink or store food in lab areas
Occupational Exposure Limits: None established for this compound; control exposure as for hazardous hormone intermediates
Appearance: White to off-white crystalline powder
Odor: Practically odorless
Melting Point: 127–134°C (varies with form)
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Practically insoluble in water; soluble in acetone, ethanol, ethyl acetate
Partition Coefficient (log Kow): Estimated >5
Vapor Pressure: Negligible at ambient temperature
Density: Approx. 1.1–1.2 g/cm³ at 20°C
pH: Not applicable (non-aqueous)
Chemical Stability: Stable under normal lab conditions (room temperature, dry environment)
Thermal Decomposition: Moderate heat yields decomposition (risk of hazardous fumes)
Reactivity: Reacts with strong oxidizing agents; ester bond hydrolyzes slowly with strong acids/bases
Hazardous Polymerization: Will not occur
Byproducts: On combustion, emits CO2, CO and possibly other organic vapors
Likely Routes of Exposure: Inhalation, skin, and eye contact
Acute Toxicity: Not well-studied in humans; animal studies on related steroids show possible endocrine disruption, potential liver toxicity after repeated doses
Effects of Short-Term Exposure: Irritation of mucous membranes, skin rash, headache
Effects of Long-Term Exposure: Hormonal imbalances, reproductive/developmental effects—the risk increases with repeated or high-dose exposure
Carcinogenicity: No long-term studies available; not listed as a known human carcinogen
Sensitization: May cause skin sensitization in susceptible individuals
Mutagenicity: Not tested, risk cannot be ruled out
Medical Conditions Aggravated: Hormone-sensitive disorders, liver/kidney issues
Ecotoxicity: Moderately toxic to aquatic organisms, based on structure and persistence
Persistence/Degradability: Biodegradation in the environment expected to be slow due to steroid backbone
Bioaccumulation: Possible due to high log Kow; risk of hormone disruption in aquatic life
Mobility: Low in soil; tightly bound; may enter surface waters through improper disposal
Other Adverse Effects: May contribute to androgen or estrogen activity in aquatic environments
Waste Treatment: Collect all waste including contaminated materials in tightly sealed marked containers
Disposal Method: Send to licensed hazardous waste treatment facility; incinerate according to local regulations
Sewer Disposal: Do not discharge to drains or waterways
Empty Containers: Rinse, destroy triple-rinsed containers, dispose as hazardous waste
