Benzocaine (CAS 94-09-7) Anesthetic API

Benzocaine (CAS 94-09-7) is a classic and reliable anesthetic API, belonging to the ester local anesthetic class. It appears as a white to slightly yellow crystalline powder, produced under strict GMP standards to ensure ≥99% purity and stable anesthetic activity, guaranteeing consistent efficacy in pharmaceutical formulations. By blocking sodium ion channels in nerve endings, it rapidly inhibits pain signal transmission, providing fast-acting and temporary local anesthesia.

This pharmaceutical-grade API complies with global pharmacopoeia standards (USP/EP/BP), making it ideal for pharmaceutical manufacturers, medical device companies, and skincare product developers. It offers excellent formulation compatibility, low systemic toxicity, and clinically validated safety. For those seeking a cost-effective, widely applicable anesthetic raw material for topical pain relief, dental procedures, or minor surgical applications, Benzocaine stands out as a trusted and time-tested solution.
