Decomposition Temperature: Decomposes producing toxic fumes
Chemical Stability: Stable under ordinary storage and handling conditions, product degrades in strong acid or oxidizing environments.
Conditions to Avoid: Exposure to moisture, prolonged heat, and incompatibles like acidic or oxidative chemicals can weaken the material or cause reactions resulting in hazardous decomposition.
Hazardous Reactions: Contact with strong acids may release toxic gases, oxidizers can enhance combustibility.
Polymerization: Not known to polymerize.
Incompatible Materials: Strong oxidizing agents, strong acids.
Decomposition Products: Sulfur dioxide, sodium oxides, carbon dioxide, carbon monoxide, and other sulfur compounds.
Acute Toxicity: Oral LD50 (rat) has been reported in the range of 1,200–1,800 mg/kg; can cause nausea, vomiting, and diarrhea if large amounts are ingested.

Serious Eye Damage: Serious irritation possible, even risk of eye injury from high concentrations or direct splashes.
Respiratory Effects: Inhalation of dust may trigger coughing and upper respiratory discomfort.
Chronic Effects: Long-term repeated exposure may lead to dermatitis, sensitization rare but possible.
Carcinogenicity: Not classified as carcinogenic by IARC, ACGIH, NTP, or OSHA.
Mutagenicity and Reproductive Toxicity: Not expected based on available data.
Aquatic Toxicity: Toxic to aquatic organisms, LC50 (fish, 96h) typically below 1 mg/L in laboratory tests, which means runoff or direct release may damage aquatic ecosystems.
Persistence and Degradability: Biodegradable under aerobic conditions, but degradation rate varies based on environmental factors.
Bioaccumulative Potential: Low potential for bioaccumulation in aquatic organisms.
