2-(5,5-Dimethyl-1,3,2-dioxaborinan-2-yl)benzoic Acid Ethyl Ester CAS 346656-34-6

Description

2-(5,5-Dimethyl-1,3,2-dioxaborinan-2-yl)benzoic Acid Ethyl Ester (CAS 346656-34-6), molecular formula C14H19BO4 and molecular weight 262.11 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(5,5-Dimethyl-1,3,2-dioxaborinan-2-yl)benzoic Acid Ethyl Ester (C14H19BO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 262.11 g/mol, it falls into the medium-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.
