2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl methanesulfonate (CAS 1245824-39-8), molecular formula C13H19BO5S and molecular weight 298.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl methanesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl methanesulfonate 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.
