Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(3-methoxyphenyl)-2,3-dihydro-1,3-thiazol-2-one.
4-(3-methoxyphenyl)-2,3-dihydro-1,3-thiazol-2-one (CAS 116269-85-3), molecular formula C10H9NO2S and molecular weight 207.25 g/mol, is a CATO reference standard with documented purity and traceability.
4-(3-methoxyphenyl)-2,3-dihydro-1,3-thiazol-2-one (C10H9NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
