Chemical Structure
Description
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 supplies 2-(4-Chlorophenyl)-2-oxoethyl 2-methyl-4-(trifluoromethyl)-1,3-thiazole-5-carboxylate (CAS 339026-40-3), a certified reference material (molecular formula C14H9ClF3NO3S, MW 363.74 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-(4-Chlorophenyl)-2-oxoethyl 2-methyl-4-(trifluoromethyl)-1,3-thiazole-5-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 363.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-(4-Chlorophenyl)-2-oxoethyl 2-methyl-4-(trifluoromethyl)-1,3-thiazole-5-carboxylate 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.
