Sodium Monochloroacetate (CAS 3926-62-3) is the sodium salt of chloroacetic acid, a white crystalline powder supplied in Technical Grade, and it acts as an alkylating agent that introduces the carboxymethyl group into organic molecules, polymers and natural fibers for CMC, surfactant and agrochemical production. The chemical is a cornerstone for the production of Carboxymethyl Cellulose (CMC) , a vital thickener used in food, pharmaceuticals, and oil drilling. Its high water solubility and reactivity make it an efficient reagent for synthesizing a wide array of surfactants and amphoteric compounds. In the agrochemical sector, SMCA is a key intermediate for various herbicides and plant growth regulators. Its consistent chemical profile ensures high-yield reactions in industrial processes, while its stable salt form offers safer handling than the parent monochloroacetic acid.
