Chemical Structure

24(RS)-Hydroxycholesterol-25,26,26,26,27,27,27-d7 CAS 144154-78-9 chemical structure

Description

The occurrence of 24(RS)-Hydroxycholesterol-25,26,26,26,27,27,27-d7 is closely related to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 24(RS)-Hydroxycholesterol-25,26,26,26,27,27,27-d7 (CAS 144154-78-9), a certified reference material (molecular formula C27H39D7O2, MW 409.70 g/mol) for analytical method development and quality control.

The molecular framework of 24(RS)-Hydroxycholesterol-25,26,26,26,27,27,27-d7 (C27H39D7O2) 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.

As a certified reference material (CRM), 24(RS)-Hydroxycholesterol-25,26,26,26,27,27,27-d7 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.
