Product Overview
Iminodiacetic acid (CAS 142-73-4) is a versatile organic dibasic acid and chelating agent, also named Diglycine. It appears as white crystalline powder with stable chemical properties. Featuring two carboxyl groups and one imino group in the molecular structure, it presents excellent metal ion chelating capacity. Our product is produced by advanced synthesis and recrystallization technology, with high purity, low impurities and stable batch consistency. It is widely used in water treatment, electroplating, chemical analysis, pesticide and pharmaceutical industries. This product is only for legal industrial production and scientific research, not for human oral consumption.
