2,5-Diisopropylimidazo[4,5-d][1,3]oxazin-7(1H)-one CAS 62948-76-9

Description

As a certified reference material (CRM), 2,5-Diisopropylimidazo[4,5-d][1,3]oxazin-7(1H)-one 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.

2,5-Diisopropylimidazo[4,5-d][1,3]oxazin-7(1H)-one (CAS 62948-76-9), molecular formula C11H15N3O2 and molecular weight 221.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,5-Diisopropylimidazo[4,5-d][1,3]oxazin-7(1H)-one (C11H15N3O2) 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.
