Common Uses: Used in organic synthesis, as an intermediate for pharmaceuticals and agrochemicals
Solubility: Slightly soluble in water, miscible with many organic solvents
Hazard Class: Harmful if inhaled, swallowed, or absorbed through the skin
Health Hazards: Can cause irritation of respiratory system, eyes, and skin; prolonged contact may lead to more serious effects such as central nervous system depression
Fire Hazards: Flammable liquid and vapor; emits toxic fumes when burned
Environmental Hazards: Harmful to aquatic life; can cause long-term adverse environmental effects
GHS Pictograms: Flammable, Harmful
Chemical Identity: Heptanenitrile
Purity: Typically over 98% by weight in commercial samples
Possible Impurities: Trace amounts of other nitriles or aliphatic hydrocarbons
Inhalation: Remove to fresh air, seek medical attention for symptoms of dizziness, nausea, or difficulty breathing
Skin Contact: Wash affected area with soap and water, remove contaminated clothing
Eye Contact: Rinse cautiously with water for at least 15 minutes, consult a healthcare provider
Ingestion: Do not induce vomiting; rinse mouth and seek medical help immediately
Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide
Unsuitable Methods: Direct streams of water risk spreading liquid
Hazardous Combustion Products: Toxic gases such as hydrogen cyanide and nitrogen oxides
Protective Gear: Firefighters should use self-contained breathing apparatus and protective clothing
Additional Advice: Cool containers with water spray to minimize risk of rupture from heat
Personal Precautions: Ventilate area, wear gloves, goggles, and suitable respirator
Environmental Precautions: Contain the spill, avoid entry into water sources or soil
Clean-up Methods: Use absorbent materials like sand or vermiculite; sweep up and dispose of in accordance with local regulations
Decontamination: Wash spill area thoroughly after clean-up
Handling Practices: Use only with adequate ventilation, avoid breathing vapors, prevent contact with skin and eyes
Storage Conditions: Store in tightly closed containers in cool, well-ventilated area, away from heat, sparks, and open flames
Incompatible Materials: Acids, oxidizing agents, strong bases
Advice for Safe Handling: Ground and bond containers when transferring liquid to prevent static discharge
Engineering Controls: Employ local exhaust ventilation or other engineering controls to keep airborne concentrations below recommended limits
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, protective clothing
Respiratory Protection: Use an approved respirator if ventilation is inadequate
Hygiene Measures: Wash hands and face thoroughly after handling; remove contaminated clothing before entering eating areas
