Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E)-3-[3-(3,4-Dimethoxyphenyl)-1-phenyl-1H-pyrazol-4-yl]-2-(3-methoxyphenyl)prop-2-enenitrile.
CATO supplies (2E)-3-[3-(3,4-Dimethoxyphenyl)-1-phenyl-1H-pyrazol-4-yl]-2-(3-methoxyphenyl)prop-2-enenitrile (CAS 956242-10-7), a certified reference material (molecular formula C27H23N3O3, MW 437.49 g/mol) for analytical method development and quality control.
The molecular framework of (2E)-3-[3-(3,4-Dimethoxyphenyl)-1-phenyl-1H-pyrazol-4-yl]-2-(3-methoxyphenyl)prop-2-enenitrile (C27H23N3O3) 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.
CATO manufactures (2E)-3-[3-(3,4-Dimethoxyphenyl)-1-phenyl-1H-pyrazol-4-yl]-2-(3-methoxyphenyl)prop-2-enenitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
