Chemical Structure

Cholesterol-3,4-13C2 CAS 78887-48-6 chemical structure

Description

CATO supplies Cholesterol-3,4-13C2 (CAS 78887-48-6), a certified reference material (molecular formula C25[13C]2H46O, MW 388.64 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, Cholesterol-3,4-13C2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 388.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Cholesterol-3,4-13C2 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.
