Advice for Firefighters: Wear self-contained breathing apparatus and protective clothing, evacuate area, contain firefighting runoff.
Personal Precautions: Wear laboratory gloves, goggles, lab coat; prevent skin contact, avoid dust formation, use respirator if needed.
Environmental Precautions: Prevent entry into drains and water courses; collect and dispose of spills promptly.
Methods for Cleaning Up: Use absorbent material for liquids, sweep up solids with minimal dust, store in a sealed chemical waste container, clean surface with soap and water.
Reference to Other Sections: Consult sections on Personal Protection, Disposal Considerations.
Handling: Handle in a chemical fume hood, minimize dust and vapor formation, avoid breathing dust, avoid skin and eye contact, wash hands and exposed skin thoroughly.
Storage: Store at 2-8°C under dry, ventilated, low-light conditions, keep away from incompatible materials such as oxidizers, acids, or bases, tightly closed in original container.
Other Information: Keep out of reach of unauthorized personnel.
Exposure Limits: No established occupational exposure limits; handle as a hazardous research chemical.
Engineering Controls: Use with local exhaust ventilation or a chemical fume hood.
Personal Protective Equipment: Chemical-resistant gloves (nitrile or equivalent), laboratory goggles or face shield, disposable lab coat or impervious apron.
Respiratory Protection: N95 or half-mask respirator for dust or aerosol formation.
General Hygiene: Wash hands before breaks and after handling, do not eat or drink in work area, avoid cross-contamination.
Appearance: White or off-white crystalline powder
Odor: Odorless or faintly organic
pH: Not applicable in solid state
Melting Point: Typically between 220-230°C (estimated based on similar compounds)
Boiling Point: Decomposes before boiling
Flash Point: Not determined; likely high due to structure
Solubility: Partially soluble in ethanol, DMSO, acetone; low solubility in water
Partition Coefficient: Estimated logP above 2, consistent with steroidal molecules
Vapor Pressure: Negligible under ambient conditions
Stability: Stable in dry, cool, light-protected environment
Reactivity: May react with strong oxidizers, strong acids or bases
Chemical Stability: Stable during normal laboratory conditions, sensitive to light and humidity
Hazardous Reactions: No hazardous polymerization expected
Conditions to Avoid: Excessive heat, moisture, direct sunlight
Incompatible Materials: Strong acids, bases, oxidizers
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, other unidentified organic fumes under strong heating
Acute Toxicity: Data not fully available, but similar compounds show low acute toxicity, hormonal disruption possible at low doses
Skin Corrosion/Irritation: May cause irritation, especially with prolonged exposure
Eye Damage/Irritation: Moderate irritant potential
Respiratory Sensitization: Risk exists in powder and dust form
Germ Cell Mutagenicity: Not established
Carcinogenicity: No direct evidence, but caution advised based on hormonal activity
Reproductive Toxicity: Strong potential for endocrine disruption and reproductive effects
Specific Target Organ Toxicity: May interfere with adrenal and reproductive hormones
Aspiration Hazard: Powder form unlikely to cause aspiration under normal conditions
Symptoms of Exposure: Irritation, changes in hormonal balance, headache, nausea, menstrual changes
Ecotoxicity: Not thoroughly tested, similar compounds show toxicity toward aquatic organisms and possible bioaccumulation
Persistence/Degradability: Expected to persist in the environment due to steroid backbone
Bioaccumulation: Potentially bioaccumulative based on chemical structure
Mobility in Soil: Low due to low water solubility
Other Adverse Effects: May affect aquatic hormone regulation, exact effects unknown
