Description
Compared with other compounds in its class, the molecular weight of 279.10 g/mol gives 5-Formyl-2-(2-morpholinoethoxy)phenylboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Formyl-2-(2-morpholinoethoxy)phenylboronic acid (CAS 2377611-16-8), molecular formula C13H18BNO5 and molecular weight 279.10 g/mol, is a CATO reference standard with documented purity and traceability.
5-Formyl-2-(2-morpholinoethoxy)phenylboronic acid (C13H18BNO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
