Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-((3,5-Dichlorophenyl)amino)-4-methylthiazole-5-carboxylic acid (CAS 928003-05-8), a certified reference material (molecular formula C11H8Cl2N2O2S, MW 303.16 g/mol) for analytical method development and quality control.
2-((3,5-Dichlorophenyl)amino)-4-methylthiazole-5-carboxylic acid (C11H8Cl2N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-((3,5-Dichlorophenyl)amino)-4-methylthiazole-5-carboxylic acid 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.
