Chemical Structure

Methyl (2E)-3-(dimethylamino)-2-{(4Z)-4-[(dimethylamino)methylene]-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl}acrylate CAS 1152430-03-9 chemical structure

Description

CATO supplies Methyl (2E)-3-(dimethylamino)-2-{(4Z)-4-[(dimethylamino)methylene]-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl}acrylate (CAS 1152430-03-9), a certified reference material (molecular formula C18H22N4O3, MW 342.39 g/mol) for analytical method development and quality control.

The molecular framework of Methyl (2E)-3-(dimethylamino)-2-{(4Z)-4-[(dimethylamino)methylene]-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl}acrylate (C18H22N4O3) 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 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.

As a certified reference material (CRM), Methyl (2E)-3-(dimethylamino)-2-{(4Z)-4-[(dimethylamino)methylene]-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl}acrylate 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.
