4 Pharmacology and Biochemistry
4.1 Absorption, Distribution and Excretion

The absorption and excretion of (14)C-benzoyl chloride was studied in male and female Holtzman albino rats. Following single oral doses of 9 to 13 mg/kg, benzoyl chloride was rapidly absorbed from the gastrointestinal tract and efficiently eliminated in the urine (90%) and feces (2%) within 48 hours. ... After 72 hours, the total radiocarbon residue in tissues was approximately 1.5% of the dose; fat liver, and kidneys contained the highest residue levels.

Elimination and distribution of (14)C-labeled benzoyl chloride in rats were very similar in many respects to that of benzoic acid.

Wang PY, Evans DW; Biomater, Med Devices, Artif Organs 5 (3): 277 (1977)


Only a small amount of radioactivity was found in the urine and the feces after application of 10 uL labeled benzoyl chloride through a small incision on the dorsal musculature of male Wistar rats, measured over a period of 15 days. Organ distribution of radioactivity 3 days after application of 10 uL labeled benzoyl chloride through a small incision on the dorsal musculature of male Wistar rats: brain< heart< kidneys< lungs< spleen< skin/muscle.

4.2 Metabolism/Metabolites

When 14C-labeled benzoyl chloride was applied to the dorsal musculature of a male Wistar rat through a small incision, only traces of radioactivity were found in the urine and feces. At 3 days post-application, most of the radioactivity remained at the site of application. The benzoyl chloride appeared to react mostly by acylation of nucleophilic groups and very little hydrolyzed to benzoic acid.

/After/ a single oral dose of labelled benzoyl chloride (9-13 mg/kg bw) administered to rats,/ ... over 90% of the metabolites in the urine were identified as benzoic acid and hippuric acid.

4.3 Biological Half-Life

The half-life of the labeled material /(benzoyl chloride)/ in the blood was 1.5 hours.
