Chemical Structure
Description
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.
4-(4-Tetrahydropyranyl)phenylboronic Acid Pinacol Ester (CAS 1312479-26-7), molecular formula C17H25BO3 and molecular weight 288.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Tetrahydropyranyl)phenylboronic Acid Pinacol Ester (C17H25BO3) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 4-(4-Tetrahydropyranyl)phenylboronic 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.
