Chemical Name: 3-Aminobenzonitrile
Common Name: Meta-Aminobenzonitrile
Chemical Formula: C7H6N2
Appearance: Off-white crystalline powder or solid
Odor: Faint, aromatic
Synonyms: m-Aminobenzonitrile
CAS Number: 618-46-2
Classification: Harmful if swallowed, inhaled, or absorbed through skin
Health Hazards: May irritate respiratory tract, skin, and eyes; possible harmful effects on the central nervous system based on analog chemicals
Environmental Hazards: May pose risk to aquatic environments if large quantities enter waterways
GHS Label Elements: Exclamation mark, hazardous to human health
Route of Exposure: Inhalation, skin and eye contact, ingestion
Substance Name: 3-Aminobenzonitrile
Purity: Usually above 98% for research and industrial use
Impurities: Trace-level isomers and byproducts depending on synthesis
Molecular Weight: 118.14 g/mol
Inhalation: Move person to fresh air right away; keep patient calm and at rest—get medical help for breathing problems
Skin Contact: Remove contaminated clothing; wash skin thoroughly with soap and water; seek attention for ongoing irritation
Eye Contact: Rinse eyes gently with water for fifteen minutes, lifting eyelids at intervals; don’t wait to seek medical assessment
Ingestion: Rinse mouth, don’t induce vomiting; call for professional medical guidance immediately
Flammability: Organic solids like this can burn when exposed to fire
Suitable Extinguishers: Use foam, dry chemical, carbon dioxide, or water spray; avoid high-pressure water jets
Hazardous Combustion Products: Burning produces toxic gases such as hydrogen cyanide and nitrogen oxides
Protective Equipment: Firefighters need self-contained breathing equipment and protective gear in fire situations
Personal Precautions: Put on protective gloves, safety goggles, and a lab coat before cleanup starts
Spill Control: Isolate area, ventilate well, and use inert absorbent such as sand—shovel mixture into sealed container
Cleanup Methods: Avoid dust formation; dispose according to regional legal requirements
Environmental Consideration: Prevent chemical from entering drains or natural waterways
Handling: Work with good ventilation, avoid breathing dust, and do not eat or smoke in work areas
Hygiene: Wash hands before breaks and after work, keep work clothes separate from street clothing
Storage Conditions: Store in tightly closed containers, in a dry, cool place separate from incompatible materials such as strong acids, strong bases, and oxidizers; keep out of direct sunlight
Engineering Controls: Use chemical fume hood or local exhaust
Eye Protection: Wear chemical splash goggles
Skin Protection: Put on nitrile or butyl rubber gloves, lab lab coat, and closed footwear
Respiratory Protection: Use NIOSH-approved dust mask if concentrations become significant
Other Protection: Emergency shower and eye-wash stations are key in laboratory and production areas
Appearance: Pale to off-white powder or crystals
Odor: Faint, aromatic odor or none perceptible
Melting Point: 47–50 °C
Boiling Point: Above 280 °C under normal pressure
Solubility: Low in water, more soluble in organic solvents like ethanol or dichloromethane
Vapor Pressure: Very low at room temperature
Molecular Weight: 118.14 g/mol
Chemical Stability: Stable at room temperature and under normal storage conditions
Incompatible Substances: Strong oxidizing agents, strong acids, and bases
Hazardous Reactions: Exothermic reactions may occur with incompatible chemicals; product can hydrolyze slowly in moist air
Decomposition Products: Cyanide and nitrogen oxides upon heating or combustion
Acute Toxicity: Data shows harmful effects after ingestion, inhalation, or skin absorption; lethal dose estimates in rodents are within low hundreds of milligrams per kilogram
Irritation: Can irritate eyes, airways, and skin
Chronic Toxicity: Not much is widely published about long-term effects, but repeated exposure to similar aromatic amines often leads to organ toxicity and potentially carcinogenic effects
Symptoms of Exposure: Headache, dizziness, respiratory discomfort, nausea; central nervous system effects are possible
Aquatic Toxicity: Likely toxic to aquatic species if released in significant quantities
Mobility: Low solubility in water means it tends to bind to soil and sediments
Persistence/Degradability: Aromatic nitriles like this are persistent in the environment without advanced treatment, breaking down slowly over time
Bioaccumulation: No clear evidence for significant bioaccumulation
Disposal Methods: Collect and send waste material to authorized hazardous waste disposal facilities
Incineration: Incinerate in a chemical incinerator with afterburner and scrubber whenever possible to minimize toxic byproducts
Regulations: Disposal must follow local, regional, and national regulations to keep risks to both people and the environment as low as possible
Shipping Classification: Not commonly regulated as a dangerous good for ground, air, or sea transport, but check with carrier since local rules can vary
Packaging Requirements: Seal in chemical-resistant containers; prevent breakage or leaks during transport
Labeling: Clearly mark packages with contents and hazard warning to alert handlers
Precautions: Separate from oxidizers and acids during transit; store in original packaging
Workplace Exposure Limits: Not established in every region, but monitoring for airborne dust is part of best practice
Chemical Inventories: Listed under various regulatory chemical inventories like TSCA in the U.S. and REACH in Europe
Labeling Requirements: Label products with clear hazard info including exclamation mark pictogram as per GHS
Worker Safety: Training and written safety programs recommended for workplaces using this substance
