Folic Acid EP Impurity H is a pharmacopoeial related substance of folic acid, the water-soluble B vitamin used in supplements, food fortification and pharmaceutical preparations. It is a pteridine-based compound with the formula C31H31N9O10 and a molecular weight of 689.63, presented as a red powder. Folic acid and its related substances are commonly handled with protection from light and oxidation, so a defined standard is needed to confirm that a separation resolves the impurity from the main peak and from degradation products and to check system suitability before quantitative runs. Laboratories use it in method development, stability-indicating studies and identification of related substances in drug substance and formulated products. Storage at -20 C +/- 5 C is specified, and transport is with ice packs. Available pack sizes span 1 mg to 1 g. Requests for a quotation and the associated analytical file are handled through the form on this page.
Also known as
