Description

Guanidine carbonate (CAS 593-85-1 ) is a stable salt form of guanidine used across chemical synthesis, personal care, and industrial processing. Its controlled alkalinity and reactivity make it a preferred source of guanidine. This material is often selected in applications where the free base or hydrochloride form is less practical to handle. In personal care formulations, it functions as a pH adjuster and active ingredient in hair products. It reacts with hair proteins to alter structure in straightening and relaxer products. Pharmaceutical and fine chemical manufacturers use it as a guanidylating agent and intermediate in the synthesis of active compounds. These compounds include antidiabetic and antimicrobial agents. In polymer and resin production, it acts as a catalyst or curing agent precursor, particularly in epoxy and melamine-based systems for industrial use. Food-grade applications include its use as a buffering agent in select formulations where alkaline pH control is required. The product is supplied as a white crystalline powder for various manufacturing needs. It is available in technical and pharmaceutical grades, with purity levels typically ranging from 98% to 99%+. Quality standards may align with USP or FCC requirements depending on the specific application. Packaging options span from small laboratory quantities to bulk industrial supply. Moisture-controlled packaging is standard given the product's sensitivity to humidity and environmental factors during storage. Contact us for supply of Guanidine carbonate Request Quote
