Notes: Stearic acid glycidyl ester-d5 is intended for use as an internal standard for the quantification of stearic acid glycidyl ester by GC- or LC-MS. Stearic acid glycidyl ester is an esterized form of stearic acid (Item No. 10011298) containing a glycidyl group. It induces the formation of subcutaneous sarcomas and pulmonary tumors in mice when administered at a doses of 0.005-10 mg/animal and induces the formation of breast carcinomas at 0.1 mg/animal.{65249} However, serum levels of stearic acid glycidyl ester are decreased in patients with prostate cancer compared to patients with benign prostatic hyperplasia and are negatively correlated with total cholesterol, LDL, and apolipoprotein B (ApoB) levels.{65250}
