Description
Disodium molybdate dihydrate (CAS 10102-40-6, EC 600-158-6) is an inorganic molybdenum salt supplied as Na2MoO4·2H2O. It carries no assigned E-code and is commonly referenced under the trade names Sodium Molybdate 2H2O and Sodium Molybdate Dihydrate. It falls within the Salts & Minerals category and is classified under HS code 28417000.
In water treatment, it functions as an anodic corrosion inhibitor, forming a protective oxide layer on ferrous metal surfaces to suppress rust formation. In agriculture and animal feed, it serves as a molybdenum micronutrient source, correcting deficiencies that impair nitrogen fixation in legume crops. It also acts as an antimicrobial agent and pigment fixative in textile and leather processing.
Disodium molybdate dihydrate is available in technical and feed-grade specifications and is subject to REACH registration requirements within the EU. Standard packaging includes 25 kg bags and bulk formats. Buyers should verify grade suitability against relevant national feed or industrial standards prior to procurement.
