2-(4-Bromo-3-chloro-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 2096341-75-0

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-Bromo-3-chloro-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2096341-75-0), molecular formula C13H17BBrClO2 and molecular weight 331.44 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H17BBrClO2, 2-(4-Bromo-3-chloro-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 331.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-Bromo-3-chloro-5-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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.
