General description
N-(2-Hydroxyethyl)iminodiacetic acid (HEIDA) is a biodegradable and strong metal chelating agent, similar to nitrilotriacetic acid (NTA).
Application
N-(2-Hydroxyethyl)iminodiacetic acid (HEIDA) can be used in the following processes:
- HEIDA can be used as a metal chelating agent for Fe(III) ion. The presence of HEIDA improves the Fenton′s destruction performance of PCE (perchloroethylene) existing as dense non-aqueous phase liquid (DNAPL) in soil slurry systems.
- Oxorhenium(V) complexes with HEIDA are used for the carboxylation of ethane by CO, with potassium peroxodisulfate (K2S2O8)/trifluoroacetic acid (TFA), to afford propionic and acetic acid in good yield.
- Vanadium complexes with HEIDA are used for the peroxidative hydroxylation of benzene and oxidation of mesitylene.

A ras oncogene-amplified recombinant BHK-21 cell line (ras-rBHK-IgG) has been established, and was shown to hyperproduce the recombinant IgG chimeric human monoclonal antibody (hMAb) AE6F4, which recognizes lung cancer cells. We found that the ras-rBHK-IgG cell could be easily cultured
