Product Description

 
EDTA-2na for pH Adjuster 139-33-3 E Thylenediamine Tetraacetic Acid Disodium Salt
Ethylenediaminetetraacetic acid is an organic compound with a chemical formula of C10H16N2O8 and a white powder at room temperature and pressure. It is a chelating agent that can be combined with two valence metal ions such as Mg2+, Ca2+, Mn2+ and Fe2+. Because most nucleases and some require Mg2+, they are often used as inhibitors of nuclease and protease, and they can also be used to remove the inhibitory effect of heavy metal ions on enzymes.
