The Uses of N-(2-HYDROXYETHYL)IMINODIACETIC ACID
N-(2-Hydroxyethyl)iminodiacetic Acid (cas# 93-62-9) is a compound useful in organic synthesis.
Definition
ChEBI: N-(2-hydroxyethyl)iminodiacetic acid is an amino dicarboxylic acid that is glycine in which both hydrogens attached to the nitrogen is substituted by a carboxymethyl group and a 2-hydroxyethyl group. It has a role as a chelator. It is an amino dicarboxylic acid and a glycine derivative. It is functionally related to an iminodiacetic acid, a propionic acid and an ethanolamine.
General Description
N-(2-Hydroxyethyl)iminodiacetic acid (HEIDA) is a biodegradable and strong metal chelating agent, similar to nitrilotriacetic acid (NTA).
