Lidocain hydrochloride

Lidocaine hydrochloride (CAS 73-78-9) is a synthetic local anaesthetic and antiarrhythmic agent, also known commercially as Xylocaine hydrochloride and Xycaine hydrochloride. It belongs to the amide class of anaesthetics and is classified as a pharmaceutical intermediate with documented activity as a skin protectant and antimicrobial agent.

In pharmaceutical formulations, lidocaine hydrochloride blocks voltage-gated sodium channels in nerve membranes, interrupting pain signal transmission and making it the active ingredient in topical anaesthetic creams, injectable solutions, and wound care products. In personal care applications, it functions as a skin protectant in formulations targeting minor skin irritation and discomfort.

Lidocaine hydrochloride is supplied as a white to off-white solid meeting Ph.Eur. and USP monograph specifications, ensuring suitability for pharmaceutical and cosmetic end uses under REACH compliance. Standard packaging formats for B2B procurement include kilogram-scale quantities, with documentation available to support regulatory submissions across EU markets.
