GHS Classification: Not classified as hazardous under current GHS guidelines
Main Hazards: Irritant effects possible on skin and eyes, respiratory discomfort after inhalation, unlikely but possible sensitization after repeated contact
Label Elements: No specific pictograms, precautionary phrases regarding physical contact
Emergency Overview: Light solid, faint musky odor, exposure rarely results in severe symptoms under standard laboratory conditions
Chemical Identity: Androsteston
CAS: 18339-16-7
Concentration: 100% pure
Impurities: Trace organics, moisture under 1% nominal
Additives: No preservatives, stabilizers, or carriers added
Inhalation: Remove source of exposure, move to fresh air, monitor for cough or throat irritation, consult a physician if symptoms persist
Skin Contact: Wash affected area with soap and plenty of water, pay extra attention to folds and under nails, seek medical advice if rash or irritation develops
Eye Contact: Rinse eyes thoroughly with water for 10-15 minutes, remove contact lenses if present, call for medical help if vision remains blurry or irritation persists
Ingestion: Rinse mouth with water, avoid inducing vomiting, consult a health professional for advice on further action
Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, or foam all work, pick one suitable for surrounding materials
Specific Hazards: Smoke or irritating gases can appear if material burns, thermal decomposition produces carbon monoxide and dioxide
Protective Equipment: Wear self-contained breathing apparatus, chemical-resistant gloves, remain upwind to avoid inhaling fumes, full protective clothing advised for significant fires
Firefighting Guidance: Try to isolate fire if safe, minimize run-off to prevent environmental impact, cool containers with water if exposed to flames
Personal Precautions: Evacuate unnecessary staff, ventilate area, avoid dust formation, wear gloves, goggles, and suitable mask
Environmental Precautions: Prevent substance from entering drains or waterways, collect spillage using non-combustible absorbent like sand or vermiculite, place in labeled waste container
Cleanup Methods: Scoop or sweep powder into sealable container, clean area with wet cloth to eliminate dust residue, dispose of contaminated materials following disposal guidelines
Handling: Work in well-ventilated place, avoid breathing dust, wear suitable gloves and goggles, never eat, drink or smoke in areas with the substance
Storage: Store in tightly closed containers, away from strong acids, bases, and oxidizers, cool and dry room below 25°C, shield from direct light, maintain secondary containment to catch leaks or spills
Exposure Limits: No established occupational limits for Androsteston by OSHA or ACGIH
Engineering Controls: Use fume hood or local exhaust, ensure eyewash and safety shower stations remain accessible
Personal Protective Equipment: Wear lab coat, chemical-resistant gloves, tight-fitting goggles, N95 mask if dust risk appears
Hygiene Measures: Wash hands after handling, remove contaminated clothing, keep all work surfaces clean and free of build-up
Appearance: White to pale yellow solid
Odor: Musk-like, faintly sharp
Melting Point: 170-173°C
Boiling Point: Not applicable (decomposes)
Solubility: Low in water, soluble in ethanol and organic solvents
Vapor Pressure: Negligible at ambient temperature
Flash Point: Not available
Partition Coefficient (Log P): 3.7
Density: 1.09 g/cm³
Stability Indicators: Stable under recommended conditions
Stability: Remains stable in dry air at room temperature, breaks down if exposed to UV or extreme heat
Reactivity: Reacts with strong oxidizers, acids, or bases
Hazardous Decomposition: Creates carbon monoxide, carbon dioxide, possibly trace volatile organics
Polymerization: No known dangerous polymerization
Acute Toxicity: Low oral, dermal, and inhalation toxicity, no strong effects observed in animal studies
Irritation: Mild skin and eye irritation possible with high concentration
Sensitization: Rarely triggers allergic skin reactions after repeated contact
Chronic Effects: Long-term exposure data not fully established, avoid unnecessary or repeated exposure, reproductive toxicity not anticipated at trace levels
Mutagenicity / Carcinogenicity: No evidence for mutagenic or carcinogenic effects
Aquatic Toxicity: No data for specific aquatic species, not soluble enough to pose major risk at typical concentrations
Persistence and Degradability: Expected to degrade slowly by microbial action
Bioaccumulation: Moderate potential because of log P value, environmental risk remains low under normal handling
Mobility: Strong tendency to bind soils, unlikely to reach groundwater quickly
Other Impacts: Avoid release to environment, prevent large-scale contamination
Waste Disposal: Assure chemical is contained in sealed, labelled container, send to properly equipped facility, do not discard with household waste or pour down drain
Contaminated Packaging: Empty containers should get triple rinse, send to specialist chemical waste stream
Special Guidance: All disposal must align with local and national chemical safety guidelines
UN Number: Not assigned
Transport Hazard Class: Not regulated under standard ADR/RID/IMDG/IATA guidelines
Packing Group: Not classified
Labelling: None required under current law
Transport Precautions: Stop containers from breaking or leaking, keep cool and sealed, check carrier rules before shipment
Inventory Status: Not on major controlled substance lists for US, EU, or Asia
Labelling Requirements: None legally required, good practice suggests hazard and identification label
Restrictions: For research use, not for food or drug manufacturing, no permitted exposure by ingestion
Other Guidelines: Observe local workplace safety and chemical handling standards, keep detailed records of storage and use
