Description
As a certified reference material (CRM), 4-(2-Methoxy-2-oxoethyl)phenylboronic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-(2-Methoxy-2-oxoethyl)phenylboronic Acid (CAS 454185-96-7), molecular formula C9H11BO4 and molecular weight 193.99 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2-Methoxy-2-oxoethyl)phenylboronic Acid (C9H11BO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
