CAS Number: 361-15-9
Synonyms: 5,6-Epoxypregnenolone
Manufacturer: Listed on product packaging or procurement documents; suppliers include scientific chemical companies
Recommended Use: Laboratory research or chemical synthesis
Emergency Contact: Refer to institution’s own safety protocol for emergencies and local poison control for high-risk situations
Classification: Not classified under most common hazard categories, but handle as a low-level toxic organic compound
Major Hazards: May cause skin and eye irritation; inhalation at high concentrations leads to respiratory effects
Signal Word: Warning
Pictograms: Exclamation mark for irritant
Potential Health Effects: Short exposure can result in minor skin redness, mild eye discomfort; accidental swallowing could lead to nausea
Chemical Composition: Epoxypregnenolone 95–100%
Impurities: May include less than 5% related steroidal epoxides or residual solvents, as per manufacturing details
Additives: No stabilizers or preservatives commonly added in pure, research-grade lots
Inhalation: Get the person to fresh air immediately; give artificial respiration if breathing has stopped; seek medical help for lasting irritation
Skin Contact: Wash off with plenty of water and soap for at least fifteen minutes; take off all contaminated clothing
Eye Contact: Rinse eyes cautiously with clean water for several minutes, removing contacts if present; seek care if symptoms persist
Ingestion: Rinse mouth with water; avoid making the victim vomit; get urgent medical advice
Most Important Symptoms: Redness, discomfort, nausea given accidental exposure
Suitable Extinguishing Media: Use dry chemical powder, CO2, or alcohol-resistant foam
Unsuitable Media: Strong water jets might spread the burning material
Specific Hazards: Toxic fumes such as carbon oxides could evolve if material burns
Protective Equipment for Firefighters: Self-contained breathing apparatus preferred; wear full-body protective gear
Special Precautions: Keep run-off water out of drains; fight fires from a safe, upwind stance
Personal Safety: Evacuate unprotected persons; avoid dust or vapor inhalation; put on gloves, goggles, and suitable lab coat
Spill Control: Absorb with inert dry material—vermiculite works; sweep up and place in chemical waste container
Area Ventilation: Open windows or turn on exhaust hoods in enclosed spaces
Environmental Protection: Prevent run-off into water systems and soil
Handling: Reduce exposure by working in a fume hood or well-ventilated area; keep containers tightly closed except when removing material; avoid rough handling to prevent container breakage
Hygiene: Wash hands and face thoroughly after using; do not eat, drink, or smoke where chemical is handled
Storage: Store at 2–8°C (refrigerated) in original container, away from incompatible substances; keep out of reach of untrained personnel
Incompatible Materials: Strong oxidizers, strong acids or bases
Engineering Controls: Use chemical fume hood or effective lab exhaust
Personal Protective Equipment: Safety goggles, nitrile gloves, long-sleeve lab clothes; emergency eyewash and safety shower should be nearby
Respiratory Protection: Appropriate dust mask or respirator if dust or vapors present
Exposure Limits: Not established for this specific compound; follow good laboratory safety limits and keep exposure as low as possible
Physical State: Solid, crystalline powder
Color: Off-white to pale yellow
Odor: Odorless or faint organic smell
Melting Point: Generally ranges from 183°C to 186°C
Solubility: Freely soluble in organic solvents such as DMSO and ethanol; little to no solubility in water
pH: Not applicable—insoluble in water
Flash Point: Data not widely available—expect high, above 100°C
Vapor Pressure: Very low at room temperature
Molecular Weight: 330.46 g/mol
Chemical Stability: Stays stable under normal conditions for lab chemicals, away from light and high heat
Conditions to Avoid: High temperatures, light exposure, prolonged air contact
Incompatible Materials: Strong oxidizing agents, acids and bases
Hazardous Decomposition Products: May yield carbon monoxide, carbon dioxide, and other volatile organics if heated to decomposition
Acute Toxicity: Limited toxicological data for humans or animals; no deaths at low concentrations in lab settings
Chronic Effects: Unknown due to lack of long-term exposure studies
Routes of Entry: Inhalation, ingestion, dermal/eye contact
Symptoms: May produce mild irritation or discomfort, rare headaches with high vapor presence, low risk of severe toxicity at research-scale handling
Carcinogenicity: Not classified as carcinogen by IARC, OSHA, or NTP
Environmental Impact: Not thoroughly studied, but low water solubility signals limited immediate aquatic toxicity
Ecotoxicity: No official studies, but chemical nature hints at potential persistence in soil and water
Degradability: Not rapidly biodegradable; breaks down slowly in the environment
Bioaccumulation: Possibility for bioaccumulation in higher organisms due to steroid framework, though confirmed data are lacking
Waste Handling: Place all used or unused material, clothing, tools, and spills into sealed, labeled containers for chemical waste
Suitable Disposal Methods: Incinerate in an approved facility; don’t dump in regular trash or down drains
Local Regulation: Follow chemical waste disposal guidelines set by local, state, or national authorities
UN Number: Not classified under standard transport codes; treat as a nonhazardous organic solid for shipping
Shipping Name: Epoxypregnenolone
Transport Hazard Class: None assigned
Packing Group: Not regulated
Special Precautions: Use sealed, impact-resistant containers; include clear labeling
Environmental Hazards: Shouldn’t be released to waterways during transport
EU Regulations: Not listed under REACH, not subject to lab-specific restrictions
US Regulations: Not registered under the Toxic Substances Control Act (TSCA); no special labeling required for lab use
International Status: No major regulatory action worldwide, but always rely on local chemical management policies
Other Standards: Handling subject to standard laboratory chemical handling rules
