Note to Physician: Treat symptomatically, monitor for irritation or sensitization
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Specific Hazards Arising from Chemical: Combustible material; may give off carbon monoxide, carbon dioxide when heated or combusted
Firefighter Protection: Wear self-contained breathing apparatus and protective clothing; avoid inhalation of combustion products
Further Advice: Remove containers from fire zone if feasible, prevent fire water runoff from entering sewers or watercourses
Personal Precautions: Use chemical-resistant gloves, goggles, and a lab coat; ventilate area; avoid breathing dust or vapors
Environmental Precautions: Prevent spillage from entering drains, waterways, or soil; contain spill using inert absorbent material
Clean-up Methods: Collect material using recommended PPE, sweep up gently to avoid dust, dispose of in accordance with regulations; clean contaminated surfaces with plenty of water and detergent
Safe Handling: Handle in a fume hood or well-ventilated area; use personal protection suggested by risk assessment; avoid all unnecessary exposure; keep away from sources of ignition
Storage Requirements: Store in tightly closed containers, cool, dry conditions; segregate from incompatible substances like acids, strong oxidizers; avoid direct sunlight and temperature extremes; label storage area clearly
Occupational Exposure Limit: No established OELs; work with substance in accordance with general chemical hygiene practices
Engineering Controls: Use fume hood, local exhaust ventilation, and mechanical ventilation as needed
Personal Protective Equipment: Chemical safety goggles, gloves made of nitrile, PVC, or other appropriate material, long-sleeved lab coat, appropriate footwear; for large-scale or poorly ventilated work, a respirator suitable for organic vapors and particulates
Hygiene Measures: Do not eat, drink, or smoke during use; wash hands and face before breaks and after finishing tasks
Appearance: White to off-white crystalline solid
Odor: Faint aromatic odor
Melting Point: 57–61°C
Boiling Point: Data not widely available, estimated above 200°C
Solubility: Soluble in organic solvents (ethanol, acetone), slightly soluble in cold water
Relative Density: Approximately 1.15–1.20 g/cm³
pH: Neutral (solution in water)
Vapor Pressure: Not significant at room temperature
Flash Point: Not established, not expected to present high flammability at ambient temperature
Chemical Stability: Stable under standard conditions and recommended storage
Conditions to Avoid: Avoid heat, open flame, and incompatibility with strong acids or oxidizers
Incompatible Materials: Strong acids, bases, oxidizing agents; vigorous reaction possible if mixed
Decomposition Products: May emit toxic fumes of carbon monoxide, carbon dioxide upon thermal decomposition
Polymerization: No hazardous polymerization expected
Acute Toxicity: Oral and dermal toxicity not fully evaluated, expected low toxicity; no major systemic effects at typical exposure levels
Skin Contact: May cause mild irritation, redness or dryness, no data on sensitization
Eye Contact: Likely to irritate; excessive exposure may result in redness, pain
Chronic Exposure: No data suggesting mutagenicity, carcinogenicity, or reproductive toxicity; repeated high exposure not recommended
Exposure Symptoms: Irritation to eyes, skin, and upper respiratory tract if exposed to dust or vapor; symptoms typically resolve upon removal from exposure
Aquatic Toxicity: No specific data; based on structure, unlikely to be highly toxic to aquatic organisms in small quantities
Persistence and Degradability: Organic structure expected to degrade over time by natural processes, but rate not quantified
Bioaccumulation: Low potential for bioaccumulation anticipated, no log Kow data available
Mobility in Soil: Moderate to low mobility expected; insoluble in water reduces risk of runoff contamination
Environmental Precautions: Prevent material from entering surface waters, groundwater, or soil
Waste Disposal: Dispose of unused product, contaminated packaging, and cleanup materials through licensed chemical waste contractor; follow local, state, and federal regulations
Methods: Incineration in approved facility preferred for large quantities; small amounts dissolved in suitable flammable solvent can be combusted in a chemical fume hood with proper care
Empty Container Warning: Containers may contain trace residues; treat them with the same care as unused chemical
