17-Epimethandienone CAS 33526-40-8 chemical structure

Description

CATO manufactures 17-Epimethandienone 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.

17-Epimethandienone (CAS 33526-40-8) is a high-purity analytical reference standard with the molecular formula C20H28O2 and a molecular weight of 300.44 g/mol.

The molecular framework of 17-Epimethandienone (C20H28O2) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
