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.
(E)-N-Mesityl-4-(5-(4-methylbenzylidene)-4-oxo-2-thioxothiazolidin-3-yl)butanamide (CAS 6605-21-6) is a high-purity analytical reference standard with the molecular formula C24H26N2O2S2 and a molecular weight of 438.61 g/mol.
The molecular framework of (E)-N-Mesityl-4-(5-(4-methylbenzylidene)-4-oxo-2-thioxothiazolidin-3-yl)butanamide (C24H26N2O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
CATO manufactures (E)-N-Mesityl-4-(5-(4-methylbenzylidene)-4-oxo-2-thioxothiazolidin-3-yl)butanamide 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.
