TOXICOLOGICAL INFORMATION
Animal Data
Inhalation 4-hour LC50: 26,200 ppm in rats
Oral ALD : 3725 mg/kg in rats
The compound is not n skin irritant but ie a mild eye
irritant. Toxic effects in rats exposed by inhalation
include central nervous system and anesthetic effects at
high concentrations. Concentrations of 0.3.5% and higher
caused cardiac sensitization in dogs. Various
cardiovascular and circulatory abnormalities have also been
reported in ot.her animals. Changes in the lungs, liver,
brain and spleen were observed in a study of rats exposed by
inhalation to 12 times the TLV. in another study at 25
times the TLV, rats, guinea pigs, and cats exhibited no
microscopic evidence of damage to the heart, lungs, kidney,
liver or spleen. Exposures by ingestion or skin resulted in
