Chemical Structure
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 (Z)-3-(5-chloro-1,3-diphenyl-1H-pyrazol-4-yl)-2-(3,4-dimethoxyphenyl)acrylonitrile (CAS 956189-95-0), a certified reference material (molecular formula C26H20ClN3O2, MW 441.91 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (Z)-3-(5-chloro-1,3-diphenyl-1H-pyrazol-4-yl)-2-(3,4-dimethoxyphenyl)acrylonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 441.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures (Z)-3-(5-chloro-1,3-diphenyl-1H-pyrazol-4-yl)-2-(3,4-dimethoxyphenyl)acrylonitrile 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.
