5-Methyl-2-(pyrazin-2-yl)thiazol-4-yl 2,4-difluorobenzoate CAS 338409-35-1

Description

5-Methyl-2-(pyrazin-2-yl)thiazol-4-yl 2,4-difluorobenzoate (CAS 338409-35-1), molecular formula C15H9F2N3O2S and molecular weight 333.31 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H9F2N3O2S, 5-Methyl-2-(pyrazin-2-yl)thiazol-4-yl 2,4-difluorobenzoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 333.31 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.

As a certified reference material (CRM), 5-Methyl-2-(pyrazin-2-yl)thiazol-4-yl 2,4-difluorobenzoate 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.
