Mometasone Furoate EP Impurity B
A corticosteroid related substance, Mometasone Furoate EP Impurity B carries the impurity designation of the mometasone furoate monograph. Its formula is C28H31ClO8S and its molecular weight is 563.06, and it is a white to off-white solid. Mometasone furoate is a synthetic glucocorticoid used in topical and inhaled preparations, and impurities of this class arise from synthesis as well as from degradation of the furoate ester and the chlorinated steroid core. Reference material of this kind lets a laboratory identify and, where required, quantify the impurity in drug substance and drug product, and demonstrate that the separation in use is fit for purpose during method validation. The stated storage condition is -20 C +/- 5 C and transport is with ice packs. Available pack sizes span 1 mg to 500 mg.
