EDTA TETRASODIUM SALT: HYDRATE Structural

What is EDTA TETRASODIUM SALT: HYDRATE?

Chemical properties

white to slightly yellow crystalline powder

The Uses of EDTA TETRASODIUM SALT: HYDRATE

Ethylenediaminetetraacetic acid tetrasodium salt hydrate is used as an inhibitor of metal ligand proteases. It also acts as a chelator of zinc ion in the active site of metalloproteases. It is used as an anticoagulant and also used in the fluorometric determination of beryllium.

The Uses of EDTA TETRASODIUM SALT: HYDRATE

Ethylenediaminetetraacetic acid tetrasodium salt hydrate has been used as an antimicrobial agent during biological ink preparation for use in biopolytronics.

The Uses of EDTA TETRASODIUM SALT: HYDRATE

EDTA is an inhibitor of metalloproteases, at effective concentrations of 1-10 mM. EDTA acts as a chelator of the zinc ion in the active site of metalloproteases, and can also inhibit other metal ion-dependent proteases such as calcium-dependent cysteine proteases. For use as an anticoagulant, disodium or tripotassium salts of EDTA are most commonly used. The optimal concentration is 1.5 mg per ml of blood.

General Description

Ethylenediaminetetraacetic acid is a poylaminocarboxylic acid commonly used as a complexing agent.
