Thovek supplies sodium molybdate dihydrate (Na2MoO4·2H2O, CAS 10102-40-6) as the standard bulk molybdenum source for nutritional and agricultural formulation. At a molecular weight of 241.95 the dihydrate carries 39.66 per cent elemental molybdenum; the anhydrous salt (CAS 7631-95-0, molecular weight 205.92) carries 46.60 per cent for buyers who need a higher-loading, low-moisture input. Molybdenum functions as the metal centre of the pterin-based molybdenum cofactor found in the mammalian molybdoenzymes sulfite oxidase, xanthine oxidoreductase, aldehyde oxidase and mitochondrial amidoxime reducing component. Sodium molybdate (molybdenum VI) is one of the three molybdenum sources permitted in EU food supplements under Annex II of Directive 2002/46/EC, alongside ammonium molybdate and potassium molybdate. Material is offered to Ph. Eur. monograph 1565 specification — content 98.0 per cent to 100.5 per cent calculated on the dried substance, loss on drying 14.0 to 16.0 per cent at 140 °C for three hours (this figure is the water of crystallisation, not a moisture defect), chlorides not more than 50 ppm, phosphates not more than 200 ppm, ammonium not more than 10 ppm and heavy metals not more than 10 ppm. FCC/food grade, feed grade and technical grades are also stocked. The physical form is a white to almost white free-flowing crystalline powder of density 3.78 g/cm³ and melting point 687 °C, freely soluble in water; milled grades to 100 mesh are produced where uniform dispersion in a low-inclusion trace element premix is required. Because molybdenum is dosed in microgram quantities in human nutrition, buyers normally take the salt as a dilute trituration or as part of a trace element premix rather than neat; Thovek can supply both the pure salt and blended carrier premixes to a stated molybdenum assay. Each lot ships with a certificate of analysis covering identification, assay, loss on drying, chlorides, sulfates, phosphates, ammonium, heavy metals by ICP-MS and microbiological limits, together with MSDS, GMP and FSSC certificates, non-GMO and allergen declarations, and halal and kosher certification on request. Exported from India under ITC-HS 28417020.
