4,4,5,5-Tetramethyl-2-(2-phenylpropyl)-1,3,2-dioxaborolane (CAS 280559-30-0), molecular formula C15H23BO2 and molecular weight 246.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4,4,5,5-Tetramethyl-2-(2-phenylpropyl)-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.15 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).
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), 4,4,5,5-Tetramethyl-2-(2-phenylpropyl)-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.
