Skin contact: Remove contaminated clothing, wash affected area thoroughly with soap and water, continue rinsing until medical help arrives.
Inhalation: Move person to fresh air; keep them warm and at rest; seek medical attention for difficulty breathing or persistent symptoms.
Ingestion: Do not induce vomiting; rinse mouth thoroughly with clean water; call poison control center or seek immediate medical help.
Medical attention: Provide product label or safety data to healthcare provider.
Suitable extinguishing media: Dry chemical, carbon dioxide, water spray or alcohol-resistant foam; use the method suited to surrounding fire.
Unsuitable extinguishing media: Strong water jets may spread spilled product.
Specific hazards: Decomposes under heat; may produce toxic fumes including nitrogen oxides, hydrogen chloride.
Protective gear for fire-fighters: Full protective clothing, breathing apparatus with independent air supply.
Advice: Contain contaminated runoff to prevent environmental release.
Personal precautions: Use appropriate protective clothing including gloves, safety goggles, and mask; avoid direct contact or inhalation.
Environmental precautions: Prevent discharge into drains, surface water, or soil. Dike spills with non-combustible absorbents.
Cleanup method: Sweep or scoop up material, place into suitable, closed containers for disposal; wash area with water and detergent.
Ventilation: Ensure adequate air flow to disperse dust or vapor.
Handling: Prevent skin and eye contact, avoid inhaling dust or vapor, do not eat or drink near this material, always wash hands after use.
Storage: Keep container tightly closed in a dry, cool, and well-ventilated space, protect from direct sunlight and incompatible materials such as strong oxidizers.
Special requirements: Use spill trays; label containers clearly.
Engineering controls: Use fume hood or local exhaust to keep airborne concentrations below recommended exposure limits.
Personal protective equipment: Chemical-resistant gloves, safety glasses with side shields, lab coat; use NIOSH-approved respirator if dusty or in poorly ventilated settings.
Exposure limit values: No established OSHA or ACGIH limits, but minimize exposure.
Hygiene measures: Remove contaminated clothing, wash before reuse, maintain clean workplace, have eyewash stations and safety showers nearby.
Appearance: White to pale yellow crystalline solid.
Odor: Slightly sweet, mild characteristic odor.
pH: 4–6 in aqueous solution.
Melting point: 185–190°C.
Boiling point: Not volatile under ambient conditions.
Solubility: Readily soluble in water, slightly soluble in ethanol.
Vapor pressure: Negligible at room temperature.
Density: Approximately 1.3 g/cm³.
Flash point: Not applicable (non-flammable).
Partition coefficient (log Pow): Low, indicates preference for aqueous phases.
Chemical stability: Stable under recommended storage conditions for at least 24 months.
Incompatible materials: Strong oxidizing agents, acids, and bases; may react exothermically.
Hazardous decomposition: Chloride gases, nitrogen oxides and carbon oxides may form during combustion or thermal decomposition.
Polymerization: Not expected under normal conditions.
Reactivity: May react with strong oxidizers with heat or gas evolution.
Acute toxicity: Low toxicity by oral, dermal, or inhalation routes based on available animal data.
Chronic effects: No reliable data for carcinogenicity, mutagenicity, or reproductive toxicity; minimization of exposure avoids unnecessary risk.
Irritation: Contact may produce mild to moderate irritation to skin and mucous membranes.
Sensitization: No evidence of sensitization in limited testing.
Symptoms of exposure: Coughing, shortness of breath, redness and tearing of the eyes, rash on skin.
Aquatic toxicity: May be harmful to aquatic organisms, avoid direct release.
Persistence and degradability: Slowly biodegradable; main concern if large quantities enter waterway.
Bioaccumulation: Low potential, based on structure and behavior in water.
Soil mobility: Moderately mobile in soil due to solubility in water.
Other adverse effects: Take care to prevent release to the broader environment.
Waste treatment methods: Dispose of via licensed chemical waste facility; do not flush down drain or landfill untreated.
Container disposal: Triple rinse containers, puncture or crush before recycling or disposal as hazardous waste.
