Stable-isotope labelled analogues serve as internal standards in quantitative LC-MS work, and Atorvastatin-d5 Calcium Salt is the pentadeuterated calcium salt form of atorvastatin, the HMG-CoA reductase inhibitor widely prescribed to lower LDL cholesterol. Five deuterium atoms replace hydrogen at defined positions, giving the molecule a mass shift that allows it to be chromatographically co-eluted with the unlabelled analyte while remaining distinguishable in the mass spectrometer. This behaviour supports isotope-dilution quantification, correction for matrix effects and recovery losses, and bioanalytical method validation in plasma or serum. The compound is a white to off-white solid with the formula 2 × C33H29D5FN2O5 · Ca and a molecular weight of 2 × 562.66 plus 40.08. Recommended storage is -20°C ± 5°C and consignments travel with ice packs. Pack sizes on the list run from 0.5 mg up to 100 mg. Ask for a quotation or technical documentation to assess fit with your assay.
