Products Description
EDTA Double functional reactivity: contains two anhydride groups that can react simultaneously with two amine- or hydroxyl-containing molecules to form crosslinked structures.
Capable of specifically chelating various metal ions for preparing immobilized metal affinity chromatography (IMAC) media.
Contains active anhydride groups, easily grafted with amino and hydroxyl groups, to introduce chelating sites into polymer supports.

FAQ
Q: What is the difference between EDTA dianhydride and common EDTA?
A: EDTA dianhydride has reactive anhydride groups and can be grafted onto polymer carriers, while ordinary EDTA stays free in solution and cannot be immobilized directly.
Q: What is its storage requirement?
A: Keep sealed, dry and cool. It will hydrolyze and lose efficacy when exposed to moisture.
Q: What is the core application of EDTA dianhydride?
A: To prepare IMAC metal chelating chromatography media for recombinant protein separation and purification.
Q: What kinds of products are mainly made with EDTA dianhydride in pharmaceutical industry?
A: It is mainly used for modification of drug carriers and targeted delivery materials, as well as synthesis of medical separation media to realize site-specific metal ion complexation.
