Vitamin D2-d3 is the trideuterated form of ergocalciferol, the plant-derived form of vitamin D, and serves as an isotopically labelled standard for the determination of vitamin D2 in foods, supplements and biological matrices. Adding a known amount of the labelled compound before sample preparation enables isotope dilution quantification, compensating for extraction losses and matrix effects that commonly affect sterol analysis. It is applied in LC-MS/MS method development and validation, calibration and recovery assessment, and in confirming the identity of ergocalciferol in complex nutritional samples. Supplied as a white solid with the formula C28H41D3O and a molecular weight of 399.67, the material requires storage at -80 °C ± 5 °C and shipment with dry ice. Available pack sizes include 1 mg, 10 mg, 50 mg and 100 mg. Further technical details and a quotation can be requested.
