Chemical Structure
Description
Structurally, (2-Ethyl-5-((tetrahydro-2H-pyran-2-yl)oxy)phenyl)boronic acid (C13H19BO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, 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 250.10 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).
(2-Ethyl-5-((tetrahydro-2H-pyran-2-yl)oxy)phenyl)boronic acid (CAS 852946-95-3) is a high-purity analytical reference standard with the molecular formula C13H19BO4 and a molecular weight of 250.10 g/mol.
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.
