Name: 2,3-Dimethylaniline
Chemical Formula: C8H11N
Synonyms: 2,3-Xylidine
CAS Number: 87-59-2
Appearance: Yellow to brownish oily liquid
Odor: Aromatic, sharp
Usage Context: This aromatic amine crops up in dye and pigment manufacturing. Factory environments sometimes rely on it in synthesis routines for photographic chemicals. Hobby chemists and industrial workers both brush up against this compound, so knowing what it is and how it acts can keep mistakes from turning serious.
Main Health Hazards: Skin and mucous membrane irritation, possible acute toxicity by inhalation, ingestion, or skin absorption, potential for methemoglobinemia
Fire Hazards: Combustible, can emit toxic fumes under fire conditions
Environmental Hazards: Harmful to aquatic organisms, persistence in soil and water raises concerns
Exposure Risks: Compounds like this, due to their volatility and the way they can slip through gloves or masks, need respect. Skin rashes, breathing trouble, and nervous system effects have been seen in people working without the right protection.
Chemical Identity: 2,3-Dimethylaniline, nearly pure in industrial lots
Impurities: Trace organic byproducts, often less than 1%
Ingredient Breakdown: Most samples bear close to 100% active component, with minor incidental residues depending on supplier and batch.
Concerns: Even minor impurities in aromatic amines can have unknown effects, so users looking for lab accuracy should demand certificates of analysis or testing logs.
Inhalation: Move the individual to fresh air quickly, keep them still, call for medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, flush affected area with running water for several minutes, avoid scrubbing
Eye Contact: Rinse eyes with plenty of water, lifting eyelids, get medical advice if irritation lingers
Ingestion: Rinse mouth, do not induce vomiting, consult emergency medical services
Notes for Workers: Prompt action lowers the odds of serious effects. If you get even a whiff or a splatter, treat it as something that won’t forgive carelessness.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Specific Hazards: Vapors may form explosive mixtures with air
Decomposition Products: Toxic gases like nitrogen oxides and carbon monoxide
Protective Equipment: Firefighters dealing with this compound need breathing apparatus and protective gear. It’s not just the flames—smoke and fumes bring their own risks.
Personal Precautions: Wear gloves, eye protection, and if ventilation is poor, a respirator
Spill Cleanup: Contain spillage, absorb with inert material such as sand or earth, collect in clearly labeled containers
Environmental Precautions: Prevent runoff into drains and waterways, avoid contaminating soil
Waste Handling: Used absorbents and waste should go to hazardous waste disposal, as regular trash won’t keep downstream users safe.
Lessons Learned: Quick, controlled cleanup and disposal aren’t just a matter of corporate rulebooks—health and neighborhood safety depend on these routines never slipping.
Handling: Use in well-ventilated spaces, minimize dust and splash, stick to dedicated containers and tools
Storage: Keep in tightly closed bottles or drums away from direct sunlight, heat, or ignition sources
Incompatibilities: Strong oxidizers, acids, and bases will trigger dangerous reactions or breakdown
Shelf Life Factors: Long-term storage demands good labeling and separation from food or personal effects in the workplace.
Worker Education: Everyday interaction with aromatic amines calls for training, not only for compliance but for self-preservation and peer safety.
Exposure Limits: No clear OSHA or ACGIH values, but limits should lean toward the cautious side
Engineering Controls: Fume hoods or local exhaust keep vapor concentrations manageable
Protective Gear: Chemical-resistant gloves, lab coats, goggles, and, in splash-prone settings, face shields
Respiratory Protection: Approved filters for organic vapors make sense in confined or poorly ventilated workrooms
Workplace Culture: It’s easy to see protective gear as a nuisance, but each layer makes long workdays less risky and gives everyone insurance against those “off” moments where attention slips.
Molecular Weight: 121.18 g/mol
Boiling Point: 225-227°C
Melting Point: -15°C
Density: About 0.99 g/cm³ at 20°C
Solubility: Insoluble in water, mixes readily with organic solvents like ethanol and ether
Vapor Pressure: Low at ambient temperatures
Color and Form: Yellow to brownish liquid; color may deepen with age or exposure to air
Odor Threshold: Sharp, recognizable at low concentrations, not easily ignored in enclosed spaces.
User Impression: The look and smell alert attentive workers long before chemical sensors chime in.
Stability: Stable under recommended conditions, may slowly oxidize in air
Reactive With: Strong oxidizers, acids, acid chlorides—reactions can be violent
Decomposition Risks: Prolonged heating or mixing with incompatible reagents releases nitrogen oxides
Storage Tips: Protect from extreme heat and keep away from accidental mixing events. Small leaks can build over time, so diligent housekeeping matters.
Acute Toxicity: Oral and dermal exposure linked to nausea, headache, dizziness, and cyanosis from methemoglobinemia
Chronic Effects: Repeated, low-level contact impacts blood, liver, and nervous system health
Routes of Exposure: Eyes, skin, lungs, digestive tract
Occupational Studies: Workers in dye industries, if unprotected, have shown increased risks for certain cancers in the past. If signs of poisoning show up—such as bluish skin or confusion—the key is to get care before the situation turns critical.
Persistence: Breaks down slowly in soil and water
Bioaccumulation: Low to moderate potential in aquatic life
Ecotoxicity: Toxic to fish and microorganisms
Environmental Experience: Down-the-drain disposal or yard spills can swamp local waterways. Agricultural researchers have watched fish populations crash after aromatic amine spills. Waste handlers and employers should look for closed-loop handling to cut this risk.
Waste Handling: Treat waste as hazardous, store in sealed, labeled containers until pick-up
Disposal Method: Chemical incineration or specialist-labeled hazardous waste facilities keep the compound out of groundwater
Contaminated Packaging: Burn or landfill only at authorized sites
Risk Reduction: The best chance to avoid hefty fines and neighborhood outrage comes from working with environmental professionals, auditing for leaks, and maintaining records that stand up to regulatory review.
UN Number: 2337
Shipping Name: 2,3-Xylidine
Hazard Class: 6.1 (Toxic Substances)
Packing Group: III
Transport Condition: Label as toxic, keep container upright and sealed, separate from oxidizers or corrosives
Lesson for Handlers: Each shipment, whether by highway or rail, should have documentation ready. Regular checks for leaks and training on response plans prevent lasting harm from routine transit.
Consulted Regulations: Workplace standards vary between countries, but many agencies classify 2,3-dimethylaniline as a hazardous substance
Labeling Requirements: Containers should carry clear, legible hazard symbols and safety advice
Employee Right-to-Know: Facilities must inform staff about risks, safe handling, and emergency protocols
Real-World Impact: Worker health outcomes improve where rules are followed—regular refresher sessions for those on the factory floor help keep the record clean.
Policy Note: Authorities and companies that ignore these rules have faced real financial and reputational hits, often after preventable injuries or community complaints. Effective communication and honesty about hazards help people build trust and avoid unpleasant surprises.
