Chemical Structure

4, 6-CHOLESTADIENE CAS 27425-93-0 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 4, 6-CHOLESTADIENE.

4, 6-CHOLESTADIENE (CAS 27425-93-0), molecular formula C27H44 and molecular weight 368.64 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4, 6-CHOLESTADIENE (C27H44) is characterized by an aromatic ring system. 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 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.

CATO manufactures 4, 6-CHOLESTADIENE 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.
