Safe Handling: Minimize dust generation, avoid contact with skin, eyes, and clothing, use only with adequate ventilation
Hygiene Practices: Wash hands thoroughly after use, remove contaminated clothing and wash before reuse
Storage Requirements: Store in a tightly sealed container, keep in a cool, dry, well-ventilated area away from incompatible materials
Incompatible Substances: Strong bases, strong oxidizers, strong acids
Storage Temperature: Room temperature, avoid direct sunlight, do not freeze
Occupational Exposure Limits: No established international limits
Engineering Controls: Use enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, lab coat, dust mask or respirator (for significant dust)
Hygiene Measures: Do not eat, drink, or smoke during use, wash hands before breaks and after handling, maintain good laboratory hygiene practices

Conditions to Avoid: Excessive heat, direct sunlight, strong oxidizing or reducing agents
Incompatible Materials: Strong acids, strong bases, oxidizers
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, possible organic vapors at high temperatures
Acute Toxicity: Data for oral, dermal, and inhalation routes not extensively published; low acute toxicity expected from analogy to related compounds
Skin Corrosion/Irritation: Possible mild irritation after prolonged contact
Serious Eye Damage/Irritation: May cause serious eye irritation, especially as a dust
Respiratory Sensitization: Dust inhalation may irritate the mucous membrane
Germ Cell Mutagenicity: No evidence found in standard screening
Carcinogenicity: Not classified as carcinogen by IARC or other authorities
Reproductive Toxicity: No data indicating hazard under normal handling
Target Organs: Eyes, skin, respiratory tract
Ecotoxicity: Data not widely available; low environmental hazard expected for small-scale laboratory releases due to low solubility and natural degradation pathways
Persistence and Degradability: Likely to degrade slowly in natural environments; non-volatile solid that breaks down over time
Bioaccumulation Potential: Not expected based on molecular structure, low potential for aquatic accumulation
Mobility in Soil: Limited mobility, binds to soil particles
Other Adverse Effects: None anticipated based on chemical characterization and limited available ecotoxicological data
