Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including aBB (20R)-Cholestane (Technical).
CATO supplies aBB (20R)-Cholestane (Technical) (CAS 69483-47-2), a certified reference material (molecular formula C27H48, MW 372.67 g/mol) for analytical method development and quality control.
Owing to an aromatic ring system, aBB (20R)-Cholestane (Technical) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures aBB (20R)-Cholestane (Technical) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
