Chemical Structure
Description
(4-(Ethylsulfonyl)phenyl)methanol (CAS 917396-45-3) is a high-purity analytical reference standard with the molecular formula C9H12O3S and a molecular weight of 200.25 g/mol.
(4-(Ethylsulfonyl)phenyl)methanol (C9H12O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
As a certified reference material (CRM), (4-(Ethylsulfonyl)phenyl)methanol 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.
