Chemical Name: 7-Methylquinoline Molecular Formula: C10H9N CAS Number: 611-22-3 Appearance: Pale yellow to amber liquid or crystalline solid, mild aromatic odor Primary Uses: Intermediate in organic synthesis, research, specialty chemical production
Hazard Class: Harmful if swallowed, skin contact may cause moderate irritation, eye contact can irritate mucous membranes Main Risks: Inhalation of vapors can irritate respiratory tract, ingestion carries toxicity risk, prolonged skin exposure increases likelihood of dermatitis Labeling Elements: Exclamation mark symbol for health hazard, environmental hazard for aquatic toxicity
Main Ingredient: 7-Methylquinoline >98% Impurities: Trace related quinolines or methylquinolines Physical State: Pure liquid or crystalline solid under ambient conditions
Inhalation: Move to fresh air, seek medical advice if dizziness or irritation persists Skin Contact: Wash with soap and water for several minutes, remove contaminated clothing Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if easy, consult a physician if irritation develops Ingestion: Rinse mouth, never give anything by mouth to an unconscious person, seek medical help
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, or alcohol-resistant foam Specific Hazards: Vapors can form explosive mixtures with air, may produce toxic fumes like nitrogen oxides when burning Protective Equipment: Chemical protective suit, self-contained breathing apparatus for fire-fighters Flash Point: Data not widely published, treat as flammable liquid in uncertain scenarios
Personal Protection: Wear gloves, protective goggles, work in well-ventilated space Environmental Precautions: Prevent product from entering drains or watercourses, absorb spill with inert material like sand or vermiculite Cleaning Up: Collect using non-sparking tools, store waste in chemically resistant, properly labeled container
Safe Handling: Keep container tightly closed, avoid breathing vapors, minimize direct contact, use spark-proof tools Storage Requirements: Store in a cool, dry, well-ventilated area, separate from incompatible materials like strong oxidizers or acids, keep away from open flames and hot surfaces Good Practice: Use chemical fume hood or local exhaust, restrict access to trained personnel
Engineering Controls: Utilize adequate ventilation or fume extraction, maintain air concentration below recommended exposure levels Respiratory Protection: Use certified respirator during high concentration or accidental release Skin Protection: Nitrile or neoprene gloves, chemical-resistant lab coat Eye Protection: Tight-fitting safety goggles or face shield Hygiene: Wash hands thoroughly after handling, avoid eating or drinking in areas where chemical is used
Molecular Weight: 143.18 g/mol Boiling Point: Approximately 243°C Melting Point: Around 20–23°C Solubility: Moderately soluble in water, freely soluble in common organic solvents such as ethanol and ether Odor: Aromatic, sometimes described as sweet or grassy Vapor Pressure: Low at ambient temperature
Chemical Stability: Stable under recommended storage and handling conditions Reactivity: Sensitive to strong oxidizers, may react with acids under certain conditions Decomposition Products: Potential to release toxic gases like nitrogen oxides and carbon oxides during thermal decomposition Incompatibilities: Strong oxidizing agents, strong acids
Acute Toxicity: Moderately toxic by ingestion, inhalation, and skin absorption based on derivatives Skin and Eye Contact: Irritation and possible inflammation if direct exposure occurs Sensitization Potential: Low, but repeated long-term exposure can cause skin dryness or cracking Chronic Effects: Limited long-term study data, but prudent handling protects against unknown chronic effects
Environmental Fate: Degrades slowly in environment, mobile in water and soil Aquatic Toxicity: Harmful to aquatic organisms, avoid release into water systems Persistence: Tendency for persistence raises concern for bioaccumulation in sensitive environments
Preferred Methods: Incinerate at high temperature in a chemical incinerator equipped with afterburner and scrubber to contain toxic emissions Container Disposal: Triple rinse, render container unusable, follow hazardous waste disposal rules for chemical residues Regulatory Compliance: Coordinate with local, state, and federal waste disposal authorities
UN Number: Data rarely available, but treat as hazardous cargo Transport Class: Flammable liquid, toxic materials Packing Group: Moderate risk, avoid shipment with oxidizers or acids Handling During Transport: Use sealed, impact-resistant containers, mark according to chemical safety standards
Control Status: Not specifically listed under major chemical control statutes, but general workplace safety and hazardous substance guidelines apply Workplace Limitation: No established occupational exposure limits, follow general chemical hygiene and laboratory safety standards Labeling Requirements: GHS compliance for hazard pictograms and safety statements, proper training for workers mandatory
