Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Isopropoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.

2-(3-Isopropoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 925916-59-2) is a high-purity analytical reference standard with the molecular formula C15H23BO3 and a molecular weight of 262.15 g/mol.

Structurally, 2-(3-Isopropoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C15H23BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 262.15 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
