Do Benzocaine hydrochloride and Benzocaine HCl refer to the same substance?

Yes. Both names indicate the hydrochloride salt form of benzocaine and correspond to the same chemical identity and CAS registration.

Is Benzocaine hydrochloride used as an industrial pharmaceutical intermediate rather than a finished dosage form?

It is typically used as an intermediate in pharmaceutical formulation and processing, not as a finished consumer-ready product.

Benzocaine hydrochloride CAS 23239-88-5

Benzocaine hydrochloride is the hydrochloride salt form of benzocaine, classified as a pharmaceutical formulation intermediate used in controlled drug manufacturing processes. As an ionized aromatic ester compound (CAS 23239-88-5), it is applied where improved solubility or handling characteristics are required during formulation and processing, while retaining the structural functionality of the parent molecule in downstream pharmaceutical systems. Industrial supply is provided with competitive factory pricing, options for customized specifications, and complete documentation including MSDS, TDS, COA, supporting bulk supply for regulated production environments.
