(2,3-Dihydro-4h-benzo[b][1,4]oxazin-4-yl)(1h-pyrazol-4-yl)methanone CAS 1306392-20-0

Description

(2,3-Dihydro-4h-benzo[b][1,4]oxazin-4-yl)(1h-pyrazol-4-yl)methanone (CAS 1306392-20-0), molecular formula C12H11N3O2 and molecular weight 229.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2,3-Dihydro-4h-benzo[b][1,4]oxazin-4-yl)(1h-pyrazol-4-yl)methanone (C12H11N3O2) is characterized by an amino-acid-derived structure, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
