Eye Contact: Rinse eyes carefully with lukewarm water for at least 15 minutes, do not rub, remove contact lenses, medical assessment is recommended if pain or vision changes persist
Ingestion: Do not induce vomiting, rinse mouth, seek immediate medical attention, never give anything by mouth to an unconscious person
Self-Protection for First Aiders: Avoid direct contact, use gloves, consider using a laboratory coat, if risk of inhalation exists provide adequate ventilation or use facemask
Suitable Extinguishing Media: Use water spray, dry chemical, foam, carbon dioxide. Do not use high-pressure water streams, avoid spreading contamination
Specific Hazards: This compound may decompose under high heat to produce toxic fumes of carbon monoxide, carbon dioxide, and other irritating or toxic gases
Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus, the compound can release hazardous gases upon combustion
Fire-Fighting Procedures: Approach fire from upwind to avoid hazardous vapors, prevent runoff from entering drains, stay upwind and keep out of low areas
Personal Precautions: Ventilate the area, avoid inhalation and skin contact, wear appropriate personal protective equipment such as gloves, goggles, and lab coat
Environmental Precautions: Prevent material from reaching drains or water sources, contain spill with inert absorbent material such as vermiculite or sand
Spill Clean-up Methods: Collect spilled solid material using non-sparking tools, avoid generating dust, place in labeled container for proper disposal
Decontamination: Wipe surfaces with damp, disposable cloths, avoid chemical cleaners that might react with compound
Reporting: Notify responsible authorities if contamination reaches environmental release thresholds
Handling: Only trained personnel should handle this material in a chemical fume hood or controlled area, do not eat, drink, or smoke in areas of use, avoid dust formation, use antistatic tools, keep containers closed when not in use
Safe Storage: Store in tightly closed containers, in a cool, dry, well-ventilated area away from light and incompatible chemicals such as oxidizers and acids, label storage location with appropriate hazard information
Incompatibilities: Strong acids, strong bases, oxidizing agents, protect from physical damage and direct sunlight
Special Requirements: Store in secondary containment in a designated chemical storage cabinet, keep away from food and drink
Exposure Limits: No occupational exposure limits have been established, handle as though toxic at low levels
Engineering Controls: Use local exhaust ventilation to minimize airborne dust, chemical fume hood is recommended for weighing and preparation
Personal Protective Equipment: Wear laboratory gloves such as nitrile, chemical splash goggles, laboratory coat, closed-toe shoes
Respiratory Protection: If dust or aerosols are generated, use a NIOSH-approved respirator appropriate for exposure level
Hygiene: Wash hands thoroughly after handling, do not wear contaminated clothing outside the lab
Appearance: Off-white to pale yellow crystalline powder, solid at room temperature
Odor: Odorless or faint, non-identifiable odor
pH: Not applicable or not determined
Melting Point: Estimated in range of 220-240°C based on related compounds
Boiling Point: Decomposition likely before boiling
Flash Point: Not determined, solid is expected to have low flammability under ambient conditions
Solubility: Poorly soluble in water, soluble in organic solvents such as methanol, chloroform, DMSO, and acetone
Partition Coefficient (Log Pow): No data available, likely moderate to high based on structure
Vapor Pressure: Negligible at room temperature
Other Properties: Stable under recommended storage, photosensitive, potential to form fine dust
Chemical Stability: Stable under recommended storage and handling conditions, material can degrade if exposed to heat, light, or incompatible substances
Reactivity: No hazardous reactivity expected under normal conditions, sensitive to strong oxidizers and acids
Hazardous Decomposition Products: Toxic oxides of carbon, possible organic acid vapors upon combustion
Polymerization: Not expected to occur
Conditions to Avoid: Excessive heat, direct sunlight, moisture, exposure to open flame
Acute Toxicity: No robust animal or human data exists, low acute oral and dermal toxicity anticipated due to steroid backbone structure, but ingestion or significant exposure could produce gastrointestinal and systemic symptoms
Local Effects: Skin and eye irritation, transient or lasting redness, swelling possible after exposure, dust causes respiratory irritation
Chronic Toxicity: Prolonged or repeated exposure might lead to liver and kidney effects, adrenal suppression possible as with other corticosteroid derivatives, not classified as carcinogenic by major agencies
Sensitization: No data available, potential for allergenic response should be considered based on related structures
Other Effects: No evidence for reproductive toxicity, mutagenicity, or teratogenicity, handle cautiously until further toxicological information becomes available
Environmental Fate: Limited biodegradability, high partitioning to sediment and organic-rich soils expected, potential to persist in the environment
Toxicity to Aquatic Organisms: Not acutely toxic at low concentrations to aquatic life, steroid structure may bioaccumulate in fish and invertebrates
Mobility in Soil: Likely low water solubility, binds tightly to soils and particulates, low mobility into groundwater
Bioaccumulation Potential: Elevated based on log Pow predictions, environmental monitoring recommended if releases occur
Other Adverse Effects: No evidence for ozone depletion or photochemical smog production, avoid dispensation to sewers or natural water bodies
Disposal Methods: Dispose of as hazardous waste according to local, regional, and national regulations, incineration in a chemical incinerator equipped with afterburner and scrubber recommended
Container Disposal: Triple rinse empty containers, deface labels, dispose similarly as chemical waste
Avoid: Disposal to drains, unrestricted landfills, or municipal waste systems, prevent environmental contamination
Waste Code: Assign waste code upon classification by authorities handling steroidal pharmaceuticals or chemical hazards
UN Number: Not assigned for this compound specifically, may require classification under research chemical or pharmaceutical intermediates
Transport Class: Non-regulated for ground and air, unless form or quantity triggers hazardous designation, check country-specific requirements
Packing Group: Not assigned, but strong, leak-proof packaging necessary to avoid dust or spills
Environmental Hazards: Not classified as marine pollutant, avoid accidental release during shipment
Special Precautions: Ensure documentation accompanies shipments, only trained personnel should ship this material, store upright and secure
