Chemical Structure
Description
CATO supplies (5E)-5-(2,3-Dichlorobenzylidene)-2-mercapto-1,3-thiazol-4(5H)-one 2729AF 90407-17-3 C10H5Cl2NOS2 (CAS 90407-17-3), a certified reference material (molecular formula C10H5Cl2NOS2, MW 290.19 g/mol) for analytical method development and quality control.
The molecular framework of (5E)-5-(2,3-Dichlorobenzylidene)-2-mercapto-1,3-thiazol-4(5H)-one 2729AF 90407-17-3 C10H5Cl2NOS2 (C10H5Cl2NOS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 (5E)-5-(2,3-Dichlorobenzylidene)-2-mercapto-1,3-thiazol-4(5H)-one 2729AF 90407-17-3 C10H5Cl2NOS2 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.
