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,4Z)-4-(Benzenesulfonyl)-5-(dimethylamino)penta-2,4-dienenitrile.
CATO supplies (2E,4Z)-4-(Benzenesulfonyl)-5-(dimethylamino)penta-2,4-dienenitrile (CAS 339276-59-4), a certified reference material (molecular formula C13H14N2O2S, MW 262.33 g/mol) for analytical method development and quality control.
(2E,4Z)-4-(Benzenesulfonyl)-5-(dimethylamino)penta-2,4-dienenitrile (C13H14N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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,4Z)-4-(Benzenesulfonyl)-5-(dimethylamino)penta-2,4-dienenitrile 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.
