CATO supplies 18-Norcholan-24-oic acid, 3,20-dihydroxy-4,4,8,14-tetramethyl-,g-lactone, (3b,5a)- 35833-72-8 (CAS 35833-72-8), a certified reference material (molecular formula C27H44O3, MW 416.64 g/mol) for analytical method development and quality control.

The molecular framework of 18-Norcholan-24-oic acid, 3,20-dihydroxy-4,4,8,14-tetramethyl-,g-lactone, (3b,5a)- 35833-72-8 (C27H44O3) is characterized by 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 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 18-Norcholan-24-oic acid, 3,20-dihydroxy-4,4,8,14-tetramethyl-,g-lactone, (3b,5a)- 35833-72-8 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.
