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 2-[(5Z)-5-[(4-Methylphenyl)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]acetic acid.
CATO supplies 2-[(5Z)-5-[(4-Methylphenyl)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]acetic acid (CAS 82158-68-7), a certified reference material (molecular formula C13H11NO3S2, MW 293.36 g/mol) for analytical method development and quality control.
The molecular framework of 2-[(5Z)-5-[(4-Methylphenyl)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]acetic acid (C13H11NO3S2) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-[(5Z)-5-[(4-Methylphenyl)methylidene]-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]acetic 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.
