Chemical Name: 1-Methyl-3-Propylbenzene
Synonyms: m-Propyl Toluene
Appearance: Clear, colorless to pale yellow liquid
Odor: Mild aromatic
Recommended Use: Intermediate for chemical synthesis, solvent in industrial applications
Physical Hazards: Flammable liquid, ignites easily, releases vapors that spread along surfaces and can flash back to the source if a fire starts nearby
Health Hazards: Can irritate skin, eyes, and respiratory system; vapor exposure may cause headaches, dizziness, or nausea; larger exposures lead to drowsiness or unconsciousness
Environmental Hazards: Toxic to aquatic organisms, long-term effects in the environment if residues get into waterways; only small quantities can cause harm
Signal Word: Warning due to fire risk and toxicity
Main Ingredient: 1-Methyl-3-Propylbenzene (CAS No. 1076-19-1)
Purity: Typically above 95%
Impurities: Other alkylbenzenes and trace solvents sometimes present based on manufacturing process, remain below significant levels for standard lab or plant use
Inhalation: Move to fresh air right away; remove contaminated clothing; seek medical attention for breathing problems
Skin Contact: Wash thoroughly with soap and water, remove clothing soaked in the chemical; keep the affected area uncovered and look for irritation
Eye Contact: Rinse carefully with water for at least fifteen minutes, hold eyelids open, contact a healthcare provider if irritation remains
Ingestion: Do not induce vomiting, rinse mouth, seek immediate medical help as chemicals like this are not safe to ingest
Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide for small fires; use water spray from a safe distance to cool nearby surfaces
Specific Hazards: Vapors may form flammable mixtures with air; burning releases toxic fumes, including carbon monoxide and carbon dioxide
Protective Equipment for Firefighters: Full protective gear and self-contained breathing apparatus essential in enclosed conditions
Personal Precautions: Evacuate area, remove ignition sources, ventilate site of spill
Cleanup: Use non-sparking tools, absorb spill with sand, earth, or inert absorbent; avoid contact with skin and eyes, collect residues in sealed containers
Environmental Precautions: Prevent runoff into drains, surface water, or soil to avoid longer-term contamination
Handling: Avoid breathing vapors, use in well-ventilated spaces, ground and bond containers and equipment especially when transferring
Storage: Keep containers tightly closed, store in a cool, shaded, well-ventilated space away from heat sources, oxidizing chemicals, and direct sunlight; store in areas with spill containment measures
Engineering Controls: Proper fume hoods, explosion-proof ventilation systems in workspaces, continuous air monitoring in larger facilities
Personal Protection: Chemical-resistant gloves, splash goggles, fire-retardant lab coats; use respirators if vapor exposure exceeds occupational limits
Hygiene: Wash hands and face before eating or drinking, avoid smoking in the work area
Physical State: Liquid
Color: Colorless to pale yellow
Boiling Point: Approximately 193-195°C
Melting Point: Not common under normal temperatures, remains liquid in ambient settings
Flash Point: Between 65°C and 70°C—well within the flammable range
Solubility: Insoluble in water, soluble in most organic solvents
Vapor Pressure: Low at room temperature, but enough to create vapors that may ignite
Chemical Stability: Stable in closed containers at room temperature away from direct sunlight and air
Hazardous Reactions: Contact with oxidizers and acids creates risk of violent reaction or hazardous byproducts
Decomposition Products: Burning or overheating releases hazardous gases, particularly carbon monoxide and various aromatic compounds
Routes of Exposure: Mainly inhalation and skin contact; rare but possible by mouth or eye splash
Acute Effects: Irritation to skin, eyes, and mucous membranes, dizziness, headache, nausea
Chronic Effects: Prolonged or repeated exposure may impact the liver and nervous system; similar to other aromatic hydrocarbons but lower volatility reduces short-term inhalation risks somewhat
Sensitization, Mutagenicity, Carcinogenicity: Evidence for these effects not conclusive in animal studies, but caution remains wise due to similarity to other benzene derivatives
Aquatic Toxicity: Harmful to aquatic life, persistence in water or soil may harm organisms over time
Bioaccumulation: Some potential for buildup in the food chain if large spills are not contained or removed
Degradability: Breaks down slowly in the environment, risk for long-term environmental impact if mismanaged
Waste Disposal: Collect unwanted product and residues in sealed, labeled containers; send for chemical incineration where available
Regulatory Requirements: Do not flush to sewer or environment, manage as hazardous waste; use qualified disposal companies for larger volumes or repeated work
UN Number: Flammable liquid classification applies; packaging must meet regulations for Class 3 flammable liquids during road, ship, or air transport
Transport Hazards: Label drums, keep away from open flames and sources of static during loading and unloading; emergency procedures for accidental release or fire needed
Chemical Inventory Status: Often listed under industrial chemical regulations, not allowed for food or medical use, subject to workplace exposure monitoring
Hazard Classification: Flammable, irritant, and environmentally hazardous under global systems such as GHS
Worker Protection Regulations: Exposure limits set based on local jurisdiction, personal protective equipment rules enforced, incident reporting duties in case of spill or overexposure
