Chemical Structure
Description
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.
(2-Chloro-4-(3-ethoxypropoxy)phenyl)boronic acid (CAS 279262-80-5) is a high-purity analytical reference standard with the molecular formula C11H16BClO4 and a molecular weight of 258.51 g/mol.
The molecular framework of (2-Chloro-4-(3-ethoxypropoxy)phenyl)boronic acid (C11H16BClO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
