Chemical Structure

4-(Bis(methylthio)methylene)-2-phenyloxazol-5(4H)-one CAS 3161-47-5 chemical structure

Description

The occurrence of 4-(Bis(methylthio)methylene)-2-phenyloxazol-5(4H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(Bis(methylthio)methylene)-2-phenyloxazol-5(4H)-one (CAS 3161-47-5), molecular formula C12H11NO2S2 and molecular weight 265.35 g/mol, is a CATO reference standard with documented purity and traceability.

4-(Bis(methylthio)methylene)-2-phenyloxazol-5(4H)-one (C12H11NO2S2) 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.

As a certified reference material (CRM), 4-(Bis(methylthio)methylene)-2-phenyloxazol-5(4H)-one 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.
