Chemical Structure
Description
The occurrence of Ethyl 2-Chloro-4-(trifluoromethyl)thiazole-5-carboxylate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 2-Chloro-4-(trifluoromethyl)thiazole-5-carboxylate (CAS 72850-52-3) is a high-purity analytical reference standard with the molecular formula C7H5ClF3NO2S and a molecular weight of 259.63 g/mol.
Based on its molecular formula C7H5ClF3NO2S, Ethyl 2-Chloro-4-(trifluoromethyl)thiazole-5-carboxylate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 259.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
