Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (2-(Cyclopentyloxy)pyrimidin-5-yl)boronic acid (CAS 2225155-04-2), a certified reference material (molecular formula C9H13BN2O3, MW 208.02 g/mol) for analytical method development and quality control.
(2-(Cyclopentyloxy)pyrimidin-5-yl)boronic acid (C9H13BN2O3) contains an amino-acid-derived structure, 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).
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.
