2-(4-Bromo-5-methylthiophen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1310404-98-8 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-(4-Bromo-5-methylthiophen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.

2-(4-Bromo-5-methylthiophen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1310404-98-8) is a high-purity analytical reference standard with the molecular formula C11H16BBrO2S and a molecular weight of 303.02 g/mol.

The molecular framework of 2-(4-Bromo-5-methylthiophen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C11H16BBrO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 2-(4-Bromo-5-methylthiophen-2-yl)-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.
