General description

Ethoxyacetic acid is biomarker of exposure to widely used industrial chemicals such as alkyl-substituted ethylene glycols and other aliphatic ethers.

Application

Ethoxyacetic acid is metabolite of glycol ether alkoxy acid and was used to evaluate its toxicity in embryonic stem cell test in mouse. It was used in zebrafish embryotoxicity test to study chemical toxicity after exposure of the complete vertebrate embryo during embryogenesis in ovo.

Biochem/physiol Actions

Ethoxyacetic acid induces testicular toxicity in rats in vivo .

A sensitive and specific method for the determination in urine of alkoxyacetic acids, the metabolites of ethylene glycol monoalkyl ethers, was developed by combining the advantages of two previously described methods. The acids were determined gas chromatographically as their pentafluorobenzylesters.
