Chemical Structure

3-n-Propyl ether-17α-estradiol CAS CATO-C4X-163615 chemical structure

Description

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 supplies 3-n-Propyl ether-17α-estradiol (CAS CATO-C4X-163615), a certified reference material (molecular formula C21H30O2, MW 314.46 g/mol) for analytical method development and quality control.

The molecular framework of 3-n-Propyl ether-17α-estradiol (C21H30O2) 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).

As a certified reference material (CRM), 3-n-Propyl ether-17α-estradiol 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.
