Chemical Structure

1-Ethyl-3,5-diphenylpyridazin-4(1H)-one CAS 59591-32-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 1-Ethyl-3,5-diphenylpyridazin-4(1H)-one (CAS 59591-32-1), a certified reference material (molecular formula C18H16N2O, MW 276.33 g/mol) for analytical method development and quality control.

The molecular framework of 1-Ethyl-3,5-diphenylpyridazin-4(1H)-one (C18H16N2O) is characterized by a steroid core, an amide group, 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), 1-Ethyl-3,5-diphenylpyridazin-4(1H)-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.
