2-Chlorobenzaldehyde might be produced when a moist skin is exposed to the riot control agent CS. CS-hydrolysis to 2-chlorobenzaldehyde and malononitrile occurs both in vitro and in vivo. No quantitative data have thus far been reported with respect to the percutaneous absorption and the cutaneous biotransformation of 2-chlorobenzaldehyde. Percutaneous absorption, biotransformation and elimination of (14)C-labeled 2-chlorobenzaldehyde was investigated in the rat. Following IV (25 uL/kg) and IP (37.5 uL/kg) (14)C-2-chlorobenzaldehyde administration to rats, the plasma radioactivity declined rapidly over a 24 hr period with similar plasma radioactivity-time profiles. Following cutaneous administration (75 uL/kg) in a closed glass-cup on the skin a slow skin penetration occurred as indicated by plasma radioactivity levels. A slow increase in plasma radioactivity was followed by a slow decline of radioactivity in plasma over a 3-day period. Most of the radioactivity was found in the urine with low levels in feces and exhaled air. The cutaneously administered radioactivity was also partly recovered from the glass-cup. For the qualitative and quantitative determination of metabolites in urine, a thin layer chromatography-radioautography method was used. The metabolic patterns of urinary excreted metabolites following cutaneous application and systemic administration of (14)C-2-chlorobenzaldehyde to rats were very similar. No parent compound was recovered from the rat urine. 2-Chlorohippuric acid was the principal urinary metabolite. Quantitatively, the urinary excretion of (14)C-2-chlorobenzyl alcohol following cutaneous application differed substantially from that after the systemic administration. There was no evidence of storage in the skin or skin toxicity of 2-chlorobenzaldehyde following cutaneous application.

Main metabolic pathways of o-chlorobenzylidene malononitrile (CS) in rabbits were estimated quantitatively following iv administration. The products of hydrolysis were o-chlorobenzaldehyde (o-Cbald) and malononitrile. The toxic actions of CS can be ascribed to o-Cbald.

Male adult Wistar rats dosed i.p. with o-substituted benzaldehydes (o-F, o-Cl, and o-Br = V, VI, and VII) excreted mercapturic acids in urine. These acids were identified as N-acetyl-S-(ortho-substituted benzyl)cysteines (I, II, III). The total mercapturic acid excretion as % dose (2.0 mmol/kg, n = 4) was 1.2 +/- 0.4, 6.8 +/- 0.9, and 10.4 +/- 2.0 for V, VI, and VII. p-Cl-benzaldehyde administered in the same dose showed a non-significant urinary thioether excretion. The aim of the investigation was to prove in vivo a postulated metabolic pathway of substituted benzaldehydes via sulfate esters to mercapturic acids. After a single administration of the sodium salts of o- and p-Cl-benzylsulfuric acid a significant increase in mercapturic acid excretion of 21.2 +/- 1.8% and 14.5 +/- 1.2% of dose (2.0 mmol/kg, n = 4) was found. By pretreatment with pyrazole the mercapturic acid excretion increased after administration of o-Cl-benzyl alcohol (IX) whereas a significant decrease was found after administration of o-Cl-benzaldehyde (VI). After simultaneous administration of ethanol with IX and VI an increase in mercapturic acid excretion was observed. After previous administration of pentachlorophenol a significant decrease in urinary mercapturic acid excretion for IX and VI was found. These findings are in accordance with a metabolic pathway of substituted benzaldehydes via benzyl alcohols, subsequently sulfate esters to the corresponding benzylmercapturic acids.
