Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3,5-Dichloro-4-ethoxyphenyl)boronic acid.
CATO supplies (3,5-Dichloro-4-ethoxyphenyl)boronic acid (CAS 1107604-10-3), a certified reference material (molecular formula C8H9BCl2O3, MW 234.87 g/mol) for analytical method development and quality control.
(3,5-Dichloro-4-ethoxyphenyl)boronic acid (C8H9BCl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
