Chemical Structure
Description
As a certified reference material (CRM), Epicholesterol-2,2,3,4,4,6-d6 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Epicholesterol-2,2,3,4,4,6-d6 (CAS 92543-07-2), a certified reference material (molecular formula C27H40D6O, MW 392.69 g/mol) for analytical method development and quality control.
Structurally, Epicholesterol-2,2,3,4,4,6-d6 (C27H40D6O) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 392.69 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
