Product description
Product overview
Methylglycinediacetic acid trisodium salt (MGDA-3Na) solid is a new biodegradable complexing agent. The product is an off-white powder or granules, available in two variants: powder (content ≥84%) and granules (content ≥80%), pH (1% solution) 11.0-12.0. Molecular formula C₇H₁₁NO₆·3Na, molecular weight 271.11, CAS 164462-16-2. MGDA is derived from natural amino acid glycine, offering excellent complexing ability and complete biodegradability, making it an ideal substitute for traditional complexing agents such as EDTA and NTA.
