Chemical Structure

2-[3-(chloromethyl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1073353-44-2 chemical structure

Description

The occurrence of 2-[3-(chloromethyl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-[3-(chloromethyl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1073353-44-2) is a high-purity analytical reference standard with the molecular formula C13H18BClO2 and a molecular weight of 252.54 g/mol.

2-[3-(chloromethyl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C13H18BClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-[3-(chloromethyl)phenyl]-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.
