2-(5-Iodo-2-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1192050-43-3 chemical structure

Description

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

CATO supplies 2-(5-Iodo-2-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1192050-43-3), a certified reference material (molecular formula C13H18BIO2, MW 344.00 g/mol) for analytical method development and quality control.

Structurally, 2-(5-Iodo-2-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C13H18BIO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine 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 344.00 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
