About Cholesterol-d7

Cholesterol-d7 is a stable isotope labelled analogue related to Cholesterol carrying the CAS registry number 83199-47-7. The compound has the formula C27H46O, corresponding to a molecular weight of 393.7 g/mol. Common synonyms include Cholesterol-25,26,26,26,27,27,27-d7 and 7alpha-Hydroxy Cholesterol-D7.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Handle it with standard laboratory precautions and appropriate personal protective equipment.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Cholesterol-d7 in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
