Name: Dichloroformylacrylic acid
Common uses: Chemical research, intermediate for synthesis
Physical description: Liquid or crystalline form with a sharp, pungent scent, often clear or pale yellow
Chemical formula: C4H2Cl2O3
Synonyms: No widely accepted common synonyms found in published chemical safety literature
Recommended use: Lab work under controlled conditions, not intended for consumer use
Hazard classes: Corrosive, toxic, irritant
Immediate dangers: Causes serious irritation to skin and eyes on contact, risk of severe burns, possible lung damage if inhaled
Chronic health risks: Long-term exposure may result in respiratory problems, or sensitization of airways
Environmental hazards: Harmful if leaked into water systems or soil
Signal word: Danger
Pictogram guidance: Corrosive and toxic symbols, based on GHS standards
Chemical identity: Dichloroformylacrylic acid (single-ingredient substance)
CAS number: Data not widely documented in public safety literature
Purity: Typically found in high purity for lab application
Impurities: Traces of related chlorinated organic compounds may be present if synthesizing on-site
Skin contact: Remove contaminated clothing, rinse affected skin immediately under running water for at least 15 minutes, apply a sterile dressing and seek medical guidance
Eye contact: Flush eyes with clean water for at least 15 minutes, lift eyelids occasionally, seek prompt medical attention
Inhalation: Move exposed person to fresh air, loosen tight clothing, monitor breathing, consult a healthcare professional right away
Ingestion: Rinse mouth thoroughly, avoid inducing vomiting, get immediate medical assistance
Additional note: Do not delay action – effects can escalate rapidly
Suitable extinguishing media: Use dry chemical, carbon dioxide, or foam; avoid water if runoff will enter waterways
Specific hazards in fire: Produces toxic fumes including phosgene, hydrogen chloride, and carbon oxides on combustion
Protective gear for firefighters: Wear full protective gear including a self-contained breathing apparatus
Advice for surrounding area: Keep bystanders away, cool exposed containers with spray mist not direct stream, ventilate area
Spill precautions: Evacuate the area, ventilate well, avoid direct contact or inhalation
Personal protective equipment: Use chemical splash goggles, gloves, lab coat, and a mask or respirator
Containment methods: Absorb with inert materials like sand or vermiculite
Clean-up: Scoop up and dispose according to hazardous waste regulations, wash area thoroughly
Environmental consideration: Block entry to drains, keep out of soil and water
Handling: Wear appropriate PPE, use only in a chemical fume hood, avoid splashing and spills
Storage: Keep in tightly closed glass or compatible plastic containers at cool temperatures, store away from acids, bases, and reducing agents
Incompatibilities: Makes dangerous gases with strong bases, oxidizers, or moisture
Hygiene: Wash hands before eating or drinking, keep contaminated items out of clean areas
Engineering controls: Chemical fume hood, exhaust ventilation, localized extraction
Eye protection: Chemical splash goggles or full-face shield
Skin protection: Chemical-resistant gloves such as nitrile, lab coats, long pants
Respiratory protection: Use a certified respirator if exposure limits are anticipated to be exceeded or in confined spaces
Limit of exposure: No established OSHA or ACGIH threshold limit values, but great caution is warranted
State: Liquid (can be crystalline at lower temperatures)
Color: Clear to pale yellow
Odor: Acrid, pungent
Melting point: Data not freely available in public records
Boiling point: Data not widely available due to instability near decomposition
Solubility: Reacts with water, miscible with some organic solvents
Vapor pressure and density: Not broadly reported, but expected to be substantial due to volatility
Chemical stability: Unstable with exposure to water, heat, or UV light; decomposes slowly in ambient moisture
Conditions to avoid: Heat, sparks, flames, strong light, contact with water or bases
Incompatible materials: Strong oxidizers, reducing agents, alkalis, acids, some plastics and metals
Hazardous decomposition: Releases phosgene, hydrogen chloride, carbon monoxide under fire or heat stress
Polymerization: May undergo hazardous polymerization if not properly stabilized
Acute toxicity: Harmful by inhalation, ingestion, or skin absorption; likely to cause burns and severe irritation
Lethal dose information: Exact LD50 statistics are not referenced in government toxicological databases, but caution is indicated from case studies
Chronic exposure: Possible pulmonary sensitization, allergic reactions, compromised lung function reported in laboratory animals
Symptoms of exposure: Redness, pain, swelling, difficulty breathing, chemical burns
Aquatic impact: Toxic to aquatic life if released into water bodies
Persistence and degradability: Not expected to degrade quickly in natural environments; likely to bioaccumulate due to chlorinated structure
Mobility in soil: Can migrate in moist soils, presenting contamination risks
Other effects: Alters pH of natural waters and disrupts ecosystems
Safe disposal: Treat as hazardous waste according to local regulations. Incineration preferred in an approved chemical incinerator
Contaminated packaging: Dispose of containers as hazardous waste, do not reuse or recycle in general waste systems
Do not: Release to surface water or public sewer
Shipping name: Dichloroformylacrylic acid, toxic, corrosive organic liquid
Hazard identification: Toxic transport class, may trigger additional hazard labels due to corrosive and environmentally harmful status
Packing group: Group II or III based on degree of hazard, per international transport authority tables
Special precautions: Containers must remain upright, secured, clearly labeled, and protected from impact and heat
Lab safety regulations: Governed by chemical hygiene standards, requires reporting and safe handling documentation
Environmental laws: Subject to local discharge and waste handling controls
OSHA or GHS: Requires written hazard communication, accessible safety data in the workplace
Other requirements: Complete staff training for anyone handling, plus annual reviews and audits as prescribed by chemical safety authorities
