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.

2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2yl)-phenol 2-hydroxyphenylboronic acid, pinacol ester 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol 2-Hydroxyphenylboronic acid pinacol ester 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2yl)phenol 2-hydroxybenzeneboronic acid, pinacol ester phenol, 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- 269409-97-4 (CAS 269409-97-4) is a high-purity analytical reference standard with the molecular formula C12H23BO3 and a molecular weight of 226.12 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2yl)-phenol 2-hydroxyphenylboronic acid, pinacol ester 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol 2-Hydroxyphenylboronic acid pinacol ester 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2yl)phenol 2-hydroxybenzeneboronic acid, pinacol ester phenol, 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- 269409-97-4 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2yl)-phenol 2-hydroxyphenylboronic acid, pinacol ester 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol 2-Hydroxyphenylboronic acid pinacol ester 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2yl)phenol 2-hydroxybenzeneboronic acid, pinacol ester phenol, 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- 269409-97-4 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.
