Serving as the deuterium-labelled form of a principal atorvastatin metabolite, ortho-Hydroxy Atorvastatin-d5 Calcium Salt is presented as the calcium salt of the ortho-hydroxylated, pentadeuterated acid. It corresponds to a metabolite formed when atorvastatin, the widely prescribed HMG-CoA reductase inhibitor, undergoes hydroxylation, and the label allows that metabolite to be tracked independently of the unlabelled species. Laboratories apply it as an internal standard and reference marker when developing and validating LC-MS/MS methods, when identifying metabolite peaks in biological samples, and when calibrating quantitative assays of atorvastatin and its metabolites. Supplied as a white to off-white solid, it is stored at -20 °C (±5 °C) and transported with ice packs. Available pack sizes are 1 mg, 2 mg, 5 mg, 10 mg, 20 mg, 25 mg, 30 mg, 50 mg and 100 mg. Quotations can be requested.
