Chemical Structure

28-Homocastasterone CAS 83509-42-6 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, 28-Homocastasterone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 478.70 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).

28-Homocastasterone (CAS 83509-42-6) is a high-purity analytical reference standard with the molecular formula C29H50O5 and a molecular weight of 478.70 g/mol.

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 28-Homocastasterone 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.
