Indication of any immediate medical attention and special treatment needed
Absorption, Distribution and ExcretionThe pharmacokinetics of chlorendic anhydride was evaluated in 4 male and 8 female Holzman's albino rats that ingested 14C-chlorendic anhydride via gavage in a single dose of 3.65 (Group 1: 2 females), 4.00 (Group 2: 4 females), 5.55 (Group 3: 2 females) or 3.62 mg/kg (Group 4: 4 males). Blood was drawn from females treated with 4 mg/kg at 1, 4, 8, 17, 24, 48, 72 and 96 hr after dosing. Urine and feces were collected daily in the Group 1, 3 and 4 rats. Animals were sacrificed 17, 96, 192 and 192 hr, respectively, after treatment, and selected tissues were excised. Regardless of sex, the primary route of excretion was the feces, 70% of the administered dose being eliminated within the first 72 hr. Only 10% of the administered dose was eliminated in the urine. After 192 hr, the maximum residues present in any tissue were <0.1 mg/kg, with the exception of the fat (0.121 mg/kg) and liver (0.296 mg/kg). The blood concentration of chlorendic anhydride peaked 1 hr after dosing and was significantly decreased by 96 hr. The absorption of chlorendic anhydride followed the two-compartment open model. The first compartment was suggested to consist of the blood and selected tissues which equilibrated rapidly, while the second compartment consisted of the fat which was slow in equilibrating and considered a deep reservoir.
Extinguishing media
In case of fire in the surroundings, use appropriate extinguishing media.

Possibility of hazardous reactions
Nonflammable
Conditions to avoid
no data available
Incompatible materials
Chlorendic anhydride will react almost quantitatively with excess methanol to form monomethyl chlorendate

Disposal methods
ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
