Chemical Structure

(25R)-Spirost-4-en-3,12-dion CAS 6875-60-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 426.59 g/mol gives (25R)-Spirost-4-en-3,12-dion distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (25R)-Spirost-4-en-3,12-dion (CAS 6875-60-1), a certified reference material (molecular formula C27H38O4, MW 426.59 g/mol) for analytical method development and quality control.

The molecular framework of (25R)-Spirost-4-en-3,12-dion (C27H38O4) 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).

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 (25R)-Spirost-4-en-3,12-dion 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.
