Carcinogenicity of Epoxides, Lactones, and Peroxy Compounds. V. Subcutaneous Injection in Rats2

Abstract
Twelve epoxides, lactones, and peroxy compounds were tested for carcinogenic activity by subcutaneous injection in rats. Three of these compounds induced sarcomas at the injection site. They are, in order of decreasing activity, glycidaldehyde, β-butyrolactone, and 2,2,4-trimethyl-3-hydroxy-3-pentenoic acid-β-lactone.
