Description

The occurrence of (4-(4-(Methylsulfonyl)phenyl)-3-phenylisoxazol-5-yl)methanol is closely related to a flavonoid core, 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-(4-(Methylsulfonyl)phenyl)-3-phenylisoxazol-5-yl)methanol (CAS 219679-59-1), molecular formula C17H15NO4S and molecular weight 329.37 g/mol, is a CATO reference standard with documented purity and traceability.

(4-(4-(Methylsulfonyl)phenyl)-3-phenylisoxazol-5-yl)methanol (C17H15NO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
