2-(3-Bromo-2-chloro-5-fluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 2409816-97-1 chemical structure

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-Bromo-2-chloro-5-fluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.

2-(3-Bromo-2-chloro-5-fluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2409816-97-1) is a high-purity analytical reference standard with the molecular formula C12H14BBrClFO2 and a molecular weight of 335.40 g/mol.

Structurally, 2-(3-Bromo-2-chloro-5-fluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C12H14BBrClFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, 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 335.40 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
