Chemical Structure
Description
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.
CATO supplies 1-(3,4-Dihydroxyphenyl)-2-(methylsulfanyl)ethan-1-one (CAS 104692-98-0), a certified reference material (molecular formula C9H10O3S, MW 198.24 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3,4-Dihydroxyphenyl)-2-(methylsulfanyl)ethan-1-one (C9H10O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), 1-(3,4-Dihydroxyphenyl)-2-(methylsulfanyl)ethan-1-one 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.
