Acute Toxicity: Oral, dermal, and inhalation toxicities not widely reported, but based on class expected LD50 in moderate range
Skin Corrosion/Irritation: May cause irritation with prolonged or repeated exposure
Eye Damage/Irritation: Can cause eye irritation, redness, tearing
Respiratory or Skin Sensitization: Sensitization effects not well documented for this compound
Chronic Effects: Sustained exposure may cause adverse effects on central nervous system, liver, or kidney based on similar drug class properties
Carcinogenicity/Mutagenicity: Long-term effects data scarce; compound not listed by IARC, NTP, OSHA as known carcinogen or mutagen
Other Health Effects: Overexposure may increase risk for CNS depression, symptoms like confusion or dizziness
Ecotoxicity: No direct studies, but compound structure suggests moderate aquatic toxicity
Persistence and Degradability: May persist under some environmental conditions, slow biodegradation likely
Bioaccumulation Potential: Neither highly bioaccumulative nor rapidly eliminated; monitor for long-term presence if discharged
