Description
As a certified reference material (CRM), 1-[4-Methyl-2-(pyridin-2-yl)-1,3-thiazol-5-yl]ethan-1-one hydrochloride 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.
1-[4-Methyl-2-(pyridin-2-yl)-1,3-thiazol-5-yl]ethan-1-one hydrochloride (CAS 1823188-47-1), molecular formula C11H10N2OSHCl and molecular weight 254.73 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H10N2OSHCl, 1-[4-Methyl-2-(pyridin-2-yl)-1,3-thiazol-5-yl]ethan-1-one hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
