Molecular Weight: 182.18 g/mol
Inhalation: Move person to fresh air, monitor for respiratory symptoms, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin with soap and water for several minutes, irritation may subside without special intervention
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes, keep eyelids open, seek medical attention if irritation continues
Ingestion: Rinse mouth, seek medical advice if large amounts swallowed, do not induce vomiting unless indicated by a professional
Symptoms: Irritation, redness, possible mild inflammation, rarely more severe effects
Suitable Extinguishing Media: Dry powder, foam, or CO2 extinguishers work best
Unsuitable Extinguishing Media: Direct water stream may cause material to splatter
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, small amounts of organic fumes
Special Protective Equipment: Standard firefighter turn-out gear, self-contained breathing apparatus if heavy smoke present
Specific Hazards: Dust may present minor explosion risk in enclosed spaces, avoid inhaling fumes
Personal Precautions: Gloves, safety glasses, limit dust exposure, avoid breathing dust
Environmental Precautions: Prevent large spills from entering drains or water courses
Cleanup Methods: Gently sweep up, place in appropriate waste disposal bag, wash area with water after solid has been collected, ventilate if indoors
Advice for Non-Emergency Personnel: Keep untrained people from area until cleaning is completed
Handling: Use in a fume hood or with local ventilation, minimize dust generation, avoid contact by using basic laboratory PPE
Storage: Store tightly closed in a cool, dry location, separate from strong acids, oxidizers, and bases; use a chemical storage cabinet where feasible
Special Considerations: Keep container well labeled, away from food and beverages, prevent unintended mixing with incompatible substances
Engineering Controls: Use with local exhaust, maintain clean work surfaces
Eye Protection: Chemical splash goggles recommended
Hand Protection: Nitrile or latex gloves provide an effective barrier
Skin Protection: Laboratory coat or apron
Respiratory Protection: Dust mask or respirator for extended exposure, especially if ventilation is inadequate
Exposure Limits: No government-set occupational exposure limit for this compound, practice sensible laboratory hygiene
Appearance: White to off-white crystalline powder
Odor: No characteristic odor
Melting Point: Around 187–188°C
Boiling Point: Decomposes before boiling
Vapor Pressure: Negligible at standard temperature
Solubility: Slightly soluble in water, more soluble in ethanol or organic solvents
pH: Acidic, value close to 3–4 for saturated aqueous solution
Other: Stable in normal laboratory conditions, not a significant source of vapor emission
Chemical Stability: Remains stable under normal use and storage conditions
Reactivity: Unlikely to react violently with common substances
Incompatible Materials: Strong oxidizers, strong acids or bases may degrade or transform substance
Hazardous Decomposition Products: Heating may produce carbon monoxide, carbon dioxide, and irritating fumes
Routes of Exposure: Skin and eye contact, inhalation of dust
Acute Toxicity: Low toxicity, based on chemical structure and reported case studies
Chronic Toxicity: No reliable evidence for significant chronic effects at laboratory handling levels
Irritation: Mild irritant for mucous membranes and skin, no sustained damage reported
Sensitization: Not identified as a skin or respiratory sensitizer in published literature
Carcinogenicity: Not listed as a carcinogen by NTP, IARC, or OSHA
Persistence and Degradability: Not expected to persist in environment, based on rapid breakdown in water and soil
Bioaccumulation: No evidence for significant accumulation in aquatic organisms
Ecotoxicity: Low toxicity, standard lab waste management recommended to prevent unnecessary release
Mobility in Soil: Limited by low water solubility; most remains localized
Waste Treatment: Collect residue and contaminated materials for disposal by licensed chemical waste company
Method: Do not flush into sewer, avoid disposing with regular solid waste
