Ezetimibe-d4

Deuterium labelling at four positions distinguishes Ezetimibe-d4 from the cholesterol absorption inhibitor ezetimibe from which it is derived, giving the formula C24H17D4F2NO3 and a molecular weight of 413.45. That small mass difference is enough to separate the labelled and unlabelled species under mass spectrometric detection, which is why the compound is typically used as an internal standard for bioanalytical assays in plasma and other biological matrices. It also supports method development and validation, system suitability assessment and the tracing of losses during sample preparation. The material is a white solid that should be held at -20 °C (±5 °C) and is transported with ice packs. Pack sizes of 1 mg, 5 mg and 25 mg are listed. Availability details, documentation and a quotation can be requested from the supplier.
