Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
1398503-83-7 4-(Methoxy-d3)phenylboronic acid (CAS 1398503-83-7), molecular formula C7H6D3BO3 and molecular weight 154.97 g/mol, is a CATO reference standard with documented purity and traceability.
1398503-83-7 4-(Methoxy-d3)phenylboronic acid (C7H6D3BO3) contains deuterium isotope labeling, 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).
As a certified reference material (CRM), 1398503-83-7 4-(Methoxy-d3)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.
