Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, {4-[(2,2-Dimethylpropoxy)sulfonyl]-3-methylphenyl}boronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
{4-[(2,2-Dimethylpropoxy)sulfonyl]-3-methylphenyl}boronic acid (CAS 2377608-71-2), molecular formula C12H19BO5S and molecular weight 286.15 g/mol, is a CATO reference standard with documented purity and traceability.
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-[(2,2-Dimethylpropoxy)sulfonyl]-3-methylphenyl}boronic acid 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.
