2-(2-Chloro-4-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1416722-82-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 268.54 g/mol gives 2-(2-Chloro-4-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2-Chloro-4-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1416722-82-1), molecular formula C13H18BClO3 and molecular weight 268.54 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2-Chloro-4-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C13H18BClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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 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-(2-Chloro-4-methoxyphenyl)-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.
