CATO supplies (7β,17β)-3-Methoxy-7-methyl-estra-1,3,5(10)-trien-17-ol (CAS 153063-86-6), a certified reference material (molecular formula C20H28O2, MW 300.44 g/mol) for analytical method development and quality control.
The molecular framework of (7β,17β)-3-Methoxy-7-methyl-estra-1,3,5(10)-trien-17-ol (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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
