4-Methyl-3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-7-boronic Acid Pinacol Ester CAS 1489264-77-8 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 4-Methyl-3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-7-boronic Acid Pinacol Ester.

4-Methyl-3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-7-boronic Acid Pinacol Ester (CAS 1489264-77-8), molecular formula C15H20BNO4 and molecular weight 289.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Methyl-3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-7-boronic Acid Pinacol Ester (C15H20BNO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-Methyl-3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-7-boronic Acid Pinacol Ester 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.
