Mycophenolate EP Impurity B
Impurity control for mycophenolic acid, an immunosuppressant used in transplant medicine, depends on having the individual related substances at hand. Mycophenolate EP Impurity B is one of those substances, a white to off-white solid of formula C17H20O6 and molecular weight 320.34. Laboratories obtain it to identify the corresponding peak in related-substance chromatograms, to test resolution and system suitability, and to prepare calibration solutions when the impurity is determined quantitatively. Working with the isolated substance also allows its response behaviour to be examined directly rather than inferred from the parent compound. Pack sizes listed for this item span 1 mg to 1 g, with 5 mg, 10 mg, 15 mg, 20 mg, 25 mg, 50 mg, 100 mg and 110 mg among the options. Store at 2 C to 8 C and ship at room temperature. Ask for a quotation and the supporting documents.
