(2e)-3-[3-(3-nitrophenyl)-1-phenyl-1h-pyrazol-4-yl]prop-2-enoic acid CAS 381214-35-3

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 (2e)-3-[3-(3-nitrophenyl)-1-phenyl-1h-pyrazol-4-yl]prop-2-enoic acid (CAS 381214-35-3), a certified reference material (molecular formula C18H13N3O4, MW 335.31 g/mol) for analytical method development and quality control.

The molecular framework of (2e)-3-[3-(3-nitrophenyl)-1-phenyl-1h-pyrazol-4-yl]prop-2-enoic acid (C18H13N3O4) is characterized by a flavonoid 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).

As a certified reference material (CRM), (2e)-3-[3-(3-nitrophenyl)-1-phenyl-1h-pyrazol-4-yl]prop-2-enoic acid 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.
