Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 392.69 g/mol gives Cholesterol-26,26,26,27,27,27-d6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Cholesterol-26,26,26,27,27,27-d6 (CAS 60816-17-3), a certified reference material (molecular formula C27H40D6O, MW 392.69 g/mol) for analytical method development and quality control.
The molecular framework of Cholesterol-26,26,26,27,27,27-d6 (C27H40D6O) is characterized by deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
