Aciclovir EP Impurity P
Aciclovir EP Impurity P is a purine derivative characterized by a 2-amino-9-(2-hydroxyethyl) substituent, representing an incomplete alkylation intermediate in Aciclovir synthesis. It retains the core guanine-like purine scaffold but lacks the terminal methyl group of the parent compound’s cyclopropane side chain, substituting it with a hydroxylated ethylene moiety. This structural deviation arises from premature termination of the cyclopropane ring formation during API synthesis. It functions as an HPLC reference standard for monitoring alkylation efficiency in Aciclovir production.
