Phenylacetic acid mustard is the major metabolite of the cancer chemotherapeutic agent Chlorambucil (HY-13593). Chlorambucil is an alkylating agent with antitumor activity^[1].

IC50: metabolite of Chlorambucil^[1]

Phenylacetic acid mustard (intraperitoneal injection; 0-20 mg/kg; 15 days) shows consistently 1.8-1.9 times greater antitumour potency than CHL, it exhibits an ED₁₅ value of 8.0 mg/kg^[2].
Phenylacetic acid mustard (intraperitoneal injection; 0-20 mg/kg; single dose) cause 50% lethality at the dose 15.9 mg/kg^[2].
