CATO supplies 4,4,5,5-Tetramethyl-2-(4-((methylsulfonyl)methyl)phenyl)-1,3,2-dioxaborolane (CAS 1383968-45-3), a certified reference material (molecular formula C14H21BO4S, MW 296.19 g/mol) for analytical method development and quality control.
The molecular framework of 4,4,5,5-Tetramethyl-2-(4-((methylsulfonyl)methyl)phenyl)-1,3,2-dioxaborolane (C14H21BO4S) 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 its high hydrophobicity (logP), 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), 4,4,5,5-Tetramethyl-2-(4-((methylsulfonyl)methyl)phenyl)-1,3,2-dioxaborolane 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.
