The occurrence of 2-Hydroxy-4-(4-((3-methyl-4-oxo-2-thioxothiazolidin-5-ylidene)methyl)benzamido)benzoic acid is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Hydroxy-4-(4-((3-methyl-4-oxo-2-thioxothiazolidin-5-ylidene)methyl)benzamido)benzoic acid (CAS 854002-29-2), a certified reference material (molecular formula C19H14N2O5S2, MW 414.45 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-Hydroxy-4-(4-((3-methyl-4-oxo-2-thioxothiazolidin-5-ylidene)methyl)benzamido)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 414.45 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.
CATO manufactures 2-Hydroxy-4-(4-((3-methyl-4-oxo-2-thioxothiazolidin-5-ylidene)methyl)benzamido)benzoic acid 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.
