Chemical Structure
Description
CATO supplies 2-Ethoxy-4-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (CAS 1801514-52-2), a certified reference material (molecular formula C15H21BO5, MW 292.14 g/mol) for analytical method development and quality control.
Structurally, 2-Ethoxy-4-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (C15H21BO5) 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 292.14 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
