5-Oxo-7a-(p-tolyl)hexahydropyrrolo[2,1-b]thiazole-3-carboxylic acid (CAS 1008704-37-7), molecular formula C14H15NO3S and molecular weight 277.34 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H15NO3S, 5-Oxo-7a-(p-tolyl)hexahydropyrrolo[2,1-b]thiazole-3-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 277.34 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.
