Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 269.25 g/mol gives 3-(4-Nitrophenyl)-3-phenylacrylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(4-Nitrophenyl)-3-phenylacrylic acid (CAS 17683-99-7), a certified reference material (molecular formula C15H11NO4, MW 269.25 g/mol) for analytical method development and quality control.
The molecular framework of 3-(4-Nitrophenyl)-3-phenylacrylic acid (C15H11NO4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-(4-Nitrophenyl)-3-phenylacrylic 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.
