2-(5-Methoxy-2-(p-tolylsulfinyl)phenyl)-4,4-dimethyl-4,5-dihydrooxazole CAS 2185788-98-9 chemical structure

Description

CATO supplies 2-(5-Methoxy-2-(p-tolylsulfinyl)phenyl)-4,4-dimethyl-4,5-dihydrooxazole (CAS 2185788-98-9), a certified reference material (molecular formula C19H21NO3S, MW 343.44 g/mol) for analytical method development and quality control.

2-(5-Methoxy-2-(p-tolylsulfinyl)phenyl)-4,4-dimethyl-4,5-dihydrooxazole (C19H21NO3S) contains a steroid core, 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), 2-(5-Methoxy-2-(p-tolylsulfinyl)phenyl)-4,4-dimethyl-4,5-dihydrooxazole 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.
