Eye Contact: Flush eyes with running water for fifteen minutes, hold eyelids open, remove any contact lenses, seek prompt medical attention for continued redness or discomfort
Skin Contact: Remove contaminated clothing, wash skin with soap and copious water, do not apply solvents or creams unless instructed by poison control, seek medical attention if irritation or rash appears
Inhalation: Move affected individual to uncontaminated air, keep at rest, seek medical advice for coughing, shortness of breath, or other exposure symptoms
Ingestion: Rinse mouth with water, drink small amounts of water if conscious, never induce vomiting except if advised by health professionals, seek immediate help for symptoms like nausea, vomiting, abdominal cramping
Acute Exposure Symptoms: Eyes (burning, reddening), skin (itching, irritation), inhalation (cough, sore throat), ingestion (nausea, cramps), call medical professionals for persistent or severe signs
Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, or foam for small-scale fires, avoid water jets which spread contaminated material
Special Hazards: Combustion produces nitrogen oxides, carbon monoxide, possibly toxic organic vapor clouds
Protective Equipment: Wear self-contained breathing apparatus, full protective gear including chemical-resistant suit, evacuate unprotected personnel
Additional Precautions: Keep containers cool by spraying with water if safe, prevent runoff from entering drains, check for re-ignition after flames extinguished, decontaminate all firefighting gear after exposure
Personal Precautions: Evacuate unnecessary personnel, ventilate area thoroughly, keep unprotected people away
Protective Equipment: Gloves, splash-proof goggles, laboratory coat or disposable chemical suit, respirator with organic vapor cartridge
Spill Cleanup Method: Sweep up powder using damp methods to avoid dust, contain spills with inert absorbent (vermiculate, sand), place collected waste in sealed labeled containers for disposal
Environmental Precautions: Prevent release to drains, waterways, or soil, notify authorities if significant quantities escape containment
Decontamination: Wash contaminated surfaces with soap and water, double bag all cleanup materials, send for hazardous waste disposal
Handling: Use only in fume hood or well-ventilated areas, open bottles slowly to avoid dust release, avoid unnecessary handling, transfer using dedicated utensils, post warnings at chemical storage and working sites
Storage: Keep container tightly closed, store in original packaging, cool dry place, protect from direct sunlight and heat sources, do not store with incompatible substances like strong acids or oxidizers
Hygiene: Always wash hands after handling, never eat or drink near workstation, remove contaminated clothing before entering clean areas
Segregation: Store away from food, animal feed, pharmaceuticals, and household goods. Dedicated chemical storage recommended.
Engineering Controls: Use chemical fume hood for all transfers, ensure continuous local exhaust ventilation, regular air monitoring, keep bench spaces clean of dust and residues
Personal Protective Equipment: Nitrile gloves, splash-resistant goggles, impermeable lab coat, certified respirator with organic vapor filter for powder handling
Occupational Exposure Limits: No published limits, exercise caution typical for unknown toxicants, minimize exposure by all reasonable methods
Biological Monitoring: Observational, no validated biomonitoring method, environmental wipe testing for laboratory hygiene possible
Appearance: Powdery to crystalline solid, pale pink to beige, can vary by purity and supplier
Odor: Mild organic, sometimes reminiscent of dry hay, but not intensely aromatic
Melting Point: Not firmly established, variable depending on assay
Boiling Point: Expected above 150°C, not confirmed
Solubility: Slightly soluble in water, dissolves in organic solvents like methanol or ethanol
pH: Neutral to slightly acidic solution in purified water
Vapor Pressure: Negligible at room temperature
Other Properties: Stable if dry and kept away from direct heat, can degrade with light or moisture exposure, stains surfaces and gloves easily, handle over disposable surfaces
Chemical Stability: Stable at normal laboratory room temperatures, sensitive to prolonged air or light exposure
Thermal Decomposition: Decomposes above 150°C, releases pungent organic fumes
Incompatible Materials: Oxidizers, strong acids, strong bases, avoid mixing with peroxides or nitric acid
Hazardous Decomposition Products: Nitrogen oxides, carbon monoxide, pyrrole-type breakdown molecules
Conditions To Avoid: Heat, open flames, extended storage in humid environments
Polymerization: No hazardous polymerization reported
Acute Toxicity: Data insufficient, likely moderate irritation risk by analogy to other pyrroles
Skin/Eye Effects: Causes redness, burning, itching, possible rash
Respiratory Effects: Cough, mild throat tightness, discomfort if inhaled
Potential Chronic Effects: No published studies, long-term health consequences unclear, best to treat as hazardous until further data
Routes of Exposure: Eyes, skin, inhalation, ingestion
Carcinogenicity: Not classified by IARC, EPA, or NTP, theoretically not expected to be potently carcinogenic but risks not ruled out
Mutagenicity/Reproductive Toxicity: Not assessed in published toxicological studies
Ecotoxicity: Not established, recommend caution due to organic structure and persistence
Persistence and Degradability: Uncertain rate, but pyrrole-related chemicals often persist in soils and water for moderate periods
Bioaccumulation Potential: Data unavailable, avoid repeated environmental release
Mobility in Soil: Low to moderate, solubility leads to slow movement through soil
Other Adverse Effects: Unknown interactions with aquatic life, risk of chemical oxygen depletion in water high if spilled in large amounts
Waste Treatment Methods: Collect in labeled hazardous waste container, do not dispose in general trash or down any drains
Chemical Neutralization: Not recommended due to fragment unpredictability with strong acids/bases
Incineration: Best to send full waste containers to specialist hazardous waste incineration facilities, notify waste handler about chemical class
Disposal of Containers: Triple rinse with compatible solvent and treat rinseate as hazardous waste, deface label before discarding
Regulatory Disposal Requirements: Subject to local, state, or federal hazardous waste regulations, labs must document every step for compliance
UN Number: No assigned UN number, shipped as research chemical
Shipping Name: Organic solid, n.o.s. (not otherwise specified), unless further classified
Transport Hazard Class: No official assignment, treat with same precautions as toxic moderate hazard laboratory chemicals
Packing Group: Treat as PG III (minor danger) for most transporters, double-bagging and secondary containment needed
Special Precautions: Never mail via standard postal service, use licensed hazmat couriers, include material safety documentation in shipment
Labelling requirements: Not subject to GHS or OSHA SDS listing due to unregistered CAS, add custom workplace label outlining all known hazards
Inventory status: Not found on US TSCA, Canadian DSL, European EINECS
Workplace Control: Laboratories adopt best practices for hazardous organics in absence of official guidance
Environmental Regulation: Any release subject to local environmental reporting, document accidental spills per EPA or equivalent rules
Other Relevant Laws: Research institutions hold primary responsibility for safety protocol, must train users and document handling procedures, external audits may request evidence of MSDS and training logs
