Product Name: 2,6-Dichlorotoluene
Chemical Formula: C7H6Cl2
CAS Number: 118-69-4
Common Uses: Commonly shows up as an intermediate in organic synthesis, particularly for making herbicides, dyes, and pharmaceuticals. Workers involved in labs, factories, or transport usually come across this compound in measurable volumes. Recognizing the material starts with its sharp, sometimes musty odor and clear-to-colorless liquid form at room temperature.
Hazard Class: Flammable liquid, acute toxicant
Main Risks: Exposure can irritate skin, eyes, and respiratory tract. Inhalation of vapors leads to headache, dizziness, or more severe nervous system effects. Prolonged or repeated exposure could lead to liver and kidney damage, and large-volume spills up the ante for fire or explosion risks.
Signal Word: Warning
Hazard Statements: May cause skin and eye irritation; toxic if swallowed or inhaled; flammable; harmful to aquatic life.
Chemical Name: 2,6-Dichlorotoluene
Purity: Typically above 98% for industrial materials; presence of other isomers or related chlorotoluenes rarely surpasses trace levels.
Other Relevant Components: Minor additives or stabilizers not always present; check lot-specific documentation if available.
Inhalation: Move affected person to fresh air quickly; if symptoms continue, medical attention is essential.
Skin Contact: Remove contaminated clothing and wash skin thoroughly with soap and water; watch for delayed symptoms.
Eye Contact: Rinse with plenty of water, lifting eyelids regularly; seek a doctor's help if irritation grows.
Ingestion: Do not force vomiting. If material is swallowed accidentally, rinse mouth and seek immediate medical attention, especially in cases of large dose.
Suitable Extinguishing Agents: Use dry chemical, carbon dioxide, or foam. Water spray can help cool surfaces but doesn’t always snuff flames for flammable organic liquids.
Hazards from Combustion: Burning can give off hydrogen chloride and phosgene, both highly toxic fumes. Anyone near a fire involving this chemical needs full protective gear, including self-contained breathing apparatus, as inhaling combustion products can be life-threatening.
Special Precautions: Bunds or dikes help contain runoff water during firefighting to stop chemical spread; good ventilation crucial to reducing vapor buildup.
Personal Protection: Wear gloves, chemical goggles, and suitable respirator to keep vapor and splashes away from skin, eyes, and lungs.
Cleanup Methods: Absorb small spills on inert material like sand or vermiculite; for larger releases, contain with non-combustible barriers and collect for proper disposal.
Environmental Precautions: Prevent product from entering drains, soil, or waterways—risk to fish and aquatic life is significant.
Ventilation: Open windows, use fume hoods or portable fans to disperse fumes.
Handling Tips: Keep containers tightly closed; always ground and bond containers to avoid static discharge; use only in well-ventilated areas.
Storage Guidance: Store in cool, dry, well-ventilated locations away from heat sources, direct sunlight, and incompatible materials like strong oxidizers or acids.
Avoid: Sparks, open flames, excessive temperatures; minimize routine handling to reduce exposure likelihood.
Engineering Controls: Fume hoods, local exhaust systems, and explosion-proof electrical fixtures make a big difference.
Personal Protective Equipment (PPE): Nitrile or neoprene gloves, chemical splash goggles, flame-resistant lab coats, and NIOSH/MSHA-approved respirators for high vapor concentrations.
Exposure Limits: No specific OSHA PEL or ACGIH TLV, but best practice sticks to the strictest safety approach—treating vapor or mist as hazardous at low concentrations.
Appearance: Colorless to pale yellow liquid
Odor: Sweet, aromatic, sometimes pungent
Boiling Point: Around 210°C
Melting Point: About -8°C
Flash Point: Circa 90°C (closed cup)
Solubility: Insoluble in water, mixes with most organic solvents
Vapor Pressure: Low at standard conditions
Density: Roughly 1.29 g/cm³ at 20°C
Chemical Stability: Stable at normal storage and handling conditions.
Reactive With: Strong oxidizing agents, acids, and alkalis; reacts exothermically, creating heat and sometimes hazardous byproducts.
Hazardous Decomposition: Chlorinated organic fumes, hydrogen chloride, and phosgene gas can form in a fire or when mixed with some chemicals.
Conditions to Avoid: High temperatures, ignition sources, direct sunlight, or contact with incompatible materials.
Acute Effects: Exposure by inhalation, ingestion, or skin contact typically irritates and may cause headache, nausea, or drowsiness. Larger doses ramp up risk of systemic toxicity, impacting central nervous system, liver or kidneys.
Health Risk Evidence: Studies on animals show organ toxicity at high doses, but existing research lacks long-term human data.
Chronic Effects: Prolonged skin contact may produce dermatitis; repeated high-level exposure possibly brings on organ effects.
Aquatic Toxicity: Very toxic to aquatic life; accidental releases threaten fish, crustaceans, and aquatic invertebrates.
Persistence and Degradability: Biodegrades slowly in soil and water, so environmental persistence is a genuine worry for waste streams.
Bioaccumulation Potential: Has moderate risk of building up in aquatic organisms, so vigilance is needed around waste handling sites.
Soil Mobility: Tends to stick to organic matter; possibility of migration to deeper soils if spilled in large amounts.
Waste Disposal: Follow state and federal guidelines; don’t pour down the drain or dump into regular trash. Specialized chemical disposal contractors render the best option, as they can process and incinerate chlorinated solvents safely.
Contaminated Packaging: Empty containers need triple rinsing before recycling or disposal; leftover residues count as hazardous waste.
UN Number: 2321 (for regulated shipments)
Transport Hazard Class: Flammable liquid, regulated under ADR/RID/IMDG/IATA
Packing Group: III (medium hazard)
Precautions: Keep sealed and upright, secure against movement; avoid heat, sparks, and open flames during shipping. Label containers with proper hazard statements to protect handlers and emergency responders.
Global Listings: Included on major chemical inventory lists such as TSCA (USA), EINECS (EU)
Labelling: GHS hazard pictograms and statements recommended for all containers.
Control Regulations: Workplace exposure rules may vary by state or jurisdiction, so always check national and local regulations. Environmental agencies often require reporting large discharges or accidental releases based on toxicity and persistence profiles.
