pH: Not applicable (non-aqueous solid)
Melting Point/Range: 230–240°C (varies with purity)
Boiling Point: Decomposes before boiling
Vapor Pressure: Negligible
Solubility: Practically insoluble in water, soluble in ethanol, methanol, chloroform
Flash Point: Data not available
Partition Coefficient (Log Kow): Not measured, expected >4 due to lipophilicity

Incompatible Materials: Strong oxidizers, acids, alkalis, bases
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, possible other organics under fire
Polymerization: No known risk of hazardous polymerization
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: Data limited; structurally related compounds show LD50 (oral, rat) 100–2000 mg/kg
Skin/Eye Irritation: Causes mild to moderate irritation with direct exposure
Sensitization: No reports of sensitization
Repeated Dose Toxicity: Not well studied; related steroidal compounds can disturb endocrine function
Carcinogenicity: Not classified; no IARC, NTP, or ACGIH listing
Mutagenicity and Reproductive Toxicity: No adequate animal or human data
Other Effects: May influence hormone pathways if absorbed in significant quantities
Aquatic Toxicity: Not tested, potentially harmful to aquatic life in large discharges
Terrestrial Impact: Expected to persist in soil for prolonged periods; low water solubility, high affinity for organic matter
Biodegradability: Not readily biodegradable
Bioaccumulation Potential: Likely to build up in aquatic organisms due to lipophilicity; lack of specific data
Mobility in Soil: Low; likely to adsorb strongly to soil particles
Other Adverse Effects: Unknown long-term impacts on ecosystems; prudent avoidance of environmental release
