2-(4-Methoxy-3-(tosyloxy)benzylsulfonyl)acetic acid (CAS 1005494-37-0), molecular formula C17H18O8S2 and molecular weight 414.45 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Methoxy-3-(tosyloxy)benzylsulfonyl)acetic acid (C17H18O8S2) contains a flavonoid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
