Chemical Structure

2-(4-((4-Bromophenoxy)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 2246545-69-5 chemical structure

Description

Structurally, 2-(4-((4-Bromophenoxy)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C19H22BBrO3) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 389.09 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2-(4-((4-Bromophenoxy)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2246545-69-5), molecular formula C19H22BBrO3 and molecular weight 389.09 g/mol, is a CATO reference standard with documented purity and traceability.

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.
