Acute Toxicity: Oral LD₅₀ (rat): not available; based on similar compounds, may cause moderate toxicity if ingested
Skin Corrosion/Irritation: May cause redness and irritation with prolonged or repeated exposure
Serious Eye Damage/Irritation: Dust or direct contact can cause irritation, tearing, redness
Respiratory Effects: Dust inhalation may trigger mild respiratory irritation
Ingestion Effects: Gastrointestinal discomfort, nausea possible; no reported severe toxic effects in small accidental doses
Dermal Toxicity: Low absorption expected unless damaged skin
Mutagenicity and Carcinogenicity: No comprehensive studies available; handle as a potentially harmful chemical until further data
Chronic Toxicity: No chronic tests reported; use prudent safety practices
Medical Conditions Aggravated by Exposure: Individuals with preexisting respiratory conditions may react to dust
Aquatic Toxicity: Not well studied; likely low water solubility decreases acute hazard but potential bioaccumulation cannot be ruled out
