Cholesteryl heptadecanoate
Cholesteryl Ester Internal Standard
Cholesteryl heptadecanoate serves as a cholesteryl ester internal standard, facilitating the precise quantification of free cholesterol in cellular samples without the interference of triglyceride hydrolysis. This reagent is particularly useful for the quantitative analysis of cholesteryl esters utilizing gas chromatography (GC) or liquid chromatography mass spectrometry (LC-MS) techniques. Its stability and specificity make it an essential tool for lipidomics research and metabolic studies.
