Chemical Structure
Description
As a certified reference material (CRM), 4-Ethyl-2-(2-morpholinoethyl)-6-phenylpyridazin-3(2H)-one hydrochloride 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.
4-Ethyl-2-(2-morpholinoethyl)-6-phenylpyridazin-3(2H)-one hydrochloride (CAS 33147-47-6), molecular formula C18H23N3O2HCl and molecular weight 349.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Ethyl-2-(2-morpholinoethyl)-6-phenylpyridazin-3(2H)-one hydrochloride (C18H23N3O2HCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
