Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-((2,6-Dichlorophenyl)amino)thiazol-4(5H)-one (CAS 324578-32-7) is a high-purity analytical reference standard with the molecular formula C9H6Cl2N2OS and a molecular weight of 261.13 g/mol.
The molecular framework of 2-((2,6-Dichlorophenyl)amino)thiazol-4(5H)-one (C9H6Cl2N2OS) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 2-((2,6-Dichlorophenyl)amino)thiazol-4(5H)-one 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.
