Riboflavin sodium phosphate

Riboflavin sodium phosphate (CAS 130-40-5 ), also known as FMN and approved as E106 in the EU, is the water-soluble salt form of Vitamin B2 designed for applications where standard riboflavin's limited aqueous solubility creates formulation challenges. Its superior solubility makes it the preferred B2 source for liquid systems, injectables, and fortified beverages where dissolution uniformity is critical. In pharmaceutical manufacturing, it is the standard choice for parenteral nutrition solutions. It is also used in injectable vitamin preparations, where complete solubility is a regulatory and formulation requirement. Food and beverage producers use it to fortify liquid products including energy drinks, infant formula, and dairy alternatives. This ingredient provides consistent, measurable B2 content across various applications. As E106, it also functions as a yellow colorant in food products, delivering both nutritional value and pigmentation in a single ingredient. In cosmetic formulations, it supports antioxidant claims and provides natural yellow coloration to serums and topical nutrient products. Riboflavin sodium phosphate is supplied as an orange-yellow crystalline powder or granules. It is available in USP , BP , and Ph. Eur. grades for pharmaceutical use, and food-grade specifications compliant with FCC standards for nutrition and food applications. Purity levels are typically stated on a dried basis, with assay specifications varying by grade. This ensures that the product meets the rigorous demands of both the pharmaceutical and food industries globally. Contact us for supply of Riboflavin sodium phosphate Request Quote
