General Notes: Remove victim from exposure, safely and promptly
Inhalation: Move to fresh air; seek medical attention if symptoms persist, such as coughing or shortness of breath
Skin Contact: Remove contaminated clothing, wash affected area thoroughly with soap and water; consult a physician for persistent irritation
Eye Contact: Flush eyes immediately with water for at least 15 minutes, lifting eyelids as needed; seek medical attention for lasting discomfort
Ingestion: Rinse mouth with water if victim is conscious; do not induce vomiting unless directed by medical personnel; seek medical advice promptly
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide
Hazardous Combustion Products: Phosphorus oxides, nitrogen oxides, carbon monoxide, and carbon dioxide
Special Protective Equipment: Wear self-contained breathing apparatus and full firefighting turnout gear
Advice for Firefighters: Approach fire from upwind; avoid inhaling gases, fumes, or vapors; use water spray to cool unopened containers; collect contaminated firefighting water separately due to potential environmental impacts
Personal Precautions: Evacuate personnel to safe areas; use suitable protective equipment such as gloves, goggles, and respirators
Environmental Precautions: Prevent further leakage or spillage if safe to do so; avoid discharge into drains and rivers; contain spill to smallest area possible
Methods for Clean-Up: Use absorbent inert material (such as sand or diatomaceous earth) to soak up liquid; collect residues into suitable waste containers for proper disposal as chemical waste
Decontamination: Wash the affected area with copious amounts of water after clean-up; ventilate enclosed areas before reuse
Safe Handling: Operate in a chemical fume hood or in well-ventilated areas; avoid contact with skin, eyes, and clothing; do not eat, drink, or smoke while using
Specific Handling Advice: Keep containers tightly closed; prevent buildup of vapors or fumes; refrain from using near sources of ignition or excessive heat
Storage Requirements: Store in original packaging, away from incompatible substances such as strong acids, bases, and oxidizers; keep in a dry, cool, well-ventilated place.
Incompatibilities: Strong oxidizing substances, mineral acids, moisture exposure can cause decomposition
Control Parameters: No occupational exposure limits have been established specifically for this chemical
Engineering Controls: Use local exhaust ventilation or mechanical ventilation to reduce exposure; maintain eyewash stations and safety showers in work areas
Personal Protective Equipment: Chemical-resistant gloves, lab coat or apron, splash-proof safety goggles or face shield, suitable respiratory protection if ventilation is inadequate
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling, before eating, and after removing protective equipment

pH: Slightly acidic to neutral (approx. pH 5–7 in water)
Melting Point: -30°C (approximate)
Boiling Point: Above 200°C at atmospheric pressure
Flash Point: Often above 150°C, check supplier’s confirmation
Vapor Pressure: Very low at standard temperature
Solubility: Miscible with water and many polar organic solvents
Viscosity: Relatively high compared to typical solvents, value dependent on temperature
Density: Approximately 1.16–1.22 g/cm³ at 20°C
Partition Coefficient (log Kow): Not determined but expected to be low due to polarity
Evaporation Rate: Negligible at room temperature
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Non-reactive in absence of incompatible substances
Possible Dangerous Reactions: Decomposes in contact with strong acids or bases; may form hazardous gases when exposed to high temperatures or incompatible materials
Conditions to Avoid: Heat, flames, sparks, moisture
Incompatible Materials: Strong oxidizing agents, acids, alkalis

Acute Toxicity: Low toxicity reported in animal tests; oral LD50 (rat) > 2000 mg/kg
Skin Irritation: May cause irritation on direct contact
Eye Irritation: Causes eye irritation; redness and tearing can occur
Respiratory System Effects: Inhalation of mists or vapors can cause irritation to nose, throat, lungs
Carcinogenicity: No definitive evidence of carcinogenicity in available literature
Repeated Dose Toxicity: Chronic or extensive exposure may cause mild systemic effects, including liver or kidney stress in animal models
Sensitization: Not classified as a sensitizer based on available data
Mutagenicity & Teratogenicity: No reliable studies identifying genetic or reproductive hazard
Ecotoxicity: Aquatic toxicology studies show possible toxicity to aquatic organisms, especially at higher concentrations or with chronic releases
Persistence and Degradability: Shows moderate persistence; not rapidly biodegradable
Bioaccumulative Potential: Expected to have low potential for bioaccumulation due to high water solubility and low partitioning into fatty tissues
Mobility in Soil: Highly mobile in soil and water; can leach into groundwater
Other Environmental Effects: May disrupt aquatic ecosystem balance if released in significant quantities
Results of PBT and vPvB Assessment: Not identified as persistent, bioaccumulative or toxic based on available data
Waste Disposal Methods: Handle chemical waste in accordance with national and local regulations; do not discharge to wastewater or natural environment; incineration preferred in licensed facilities; collect residues and contaminated materials as hazardous chemical waste
Contaminated Packaging: Empty containers must be triple-rinsed and managed as hazardous waste under local disposal requirements; labels should not be removed until container disposed of or decontaminated
