Chemical Structure

Mesurol Phenol Sulfoxide CAS 22454-92-8 chemical structure

Description

As a certified reference material (CRM), Mesurol Phenol Sulfoxide 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.

Mesurol Phenol Sulfoxide (CAS 22454-92-8) is a high-purity analytical reference standard with the molecular formula C9H12O2S and a molecular weight of 184.26 g/mol.

Mesurol Phenol Sulfoxide (C9H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
