2-(5-[1,3]Dioxolan-2-yl-2,4-dimethoxy-phenyl)-boronic acid pinacol ester (CAS 552845-85-9) is a high-purity analytical reference standard with the molecular formula C17H25BO6 and a molecular weight of 336.19 g/mol.
The molecular framework of 2-(5-[1,3]Dioxolan-2-yl-2,4-dimethoxy-phenyl)-boronic acid pinacol ester (C17H25BO6) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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).
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), 2-(5-[1,3]Dioxolan-2-yl-2,4-dimethoxy-phenyl)-boronic acid pinacol ester 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.
