2-((3-Cyano-6-phenyl-4-(p-tolyl)pyridin-2-yl)thio)-N-(3-nitrophenyl)propanamide CAS 332128-03-7

Description

2-((3-Cyano-6-phenyl-4-(p-tolyl)pyridin-2-yl)thio)-N-(3-nitrophenyl)propanamide (CAS 332128-03-7), molecular formula C28H22N4O3S and molecular weight 494.56 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-((3-Cyano-6-phenyl-4-(p-tolyl)pyridin-2-yl)thio)-N-(3-nitrophenyl)propanamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 494.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 2-((3-Cyano-6-phenyl-4-(p-tolyl)pyridin-2-yl)thio)-N-(3-nitrophenyl)propanamide 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.
