Chemical Structure

N-Desethyl-E-Clomiphene CAS 79838-50-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Desethyl-E-Clomiphene.

CATO supplies N-Desethyl-E-Clomiphene (CAS 79838-50-9), a certified reference material (molecular formula C24H24ClNOHCl, MW 414.37 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-Desethyl-E-Clomiphene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 414.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), N-Desethyl-E-Clomiphene 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.
