Chemical Structure
Description
The occurrence of 17B(H)-Hop-21(22)-en-3-one is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 17B(H)-Hop-21(22)-en-3-one (CAS 17152-56-6), a certified reference material (molecular formula C30H48O, MW 424.70 g/mol) for analytical method development and quality control.
The molecular framework of 17B(H)-Hop-21(22)-en-3-one (C30H48O) 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.
As a certified reference material (CRM), 17B(H)-Hop-21(22)-en-3-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
