Chemical Structure

17B(H),21B(H)-22-Hydroxyhopane CAS 1721-59-1 chemical structure

Description

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.

17B(H),21B(H)-22-Hydroxyhopane (CAS 1721-59-1), molecular formula C30H52O and molecular weight 428.73 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 17B(H),21B(H)-22-Hydroxyhopane (C30H52O) 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 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).

CATO manufactures 17B(H),21B(H)-22-Hydroxyhopane 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.
