What is Sodium chloroacetate?
Sodium chloroacetate (CAS 3926-62-3), also sold as Monoxone and abbreviated SMCA, is the sodium salt form of chloroacetic acid; a reactive intermediate and biocidal agent.
Where is Sodium chloroacetate used?
- Pharmaceutical manufacturing: synthesis of carboxymethyl derivatives and API intermediates
- Agrochemicals: selective herbicide intermediate for chloroacetic acid-based weed control actives
- Personal care: production of carboxymethyl cellulose (CMC) and betaine-type surfactants for shampoos and skin cleansers
- It serves as a biocidal agent controlling microbial growth in specific process environments.
Commercial specifications
- Purity specifications typically ranging from 97% to 99%+
- Packaging in bags and drums suited to bulk industrial procurement
