4H-benzo[b]imidazo[1,2-d][1,4]oxazine-6-carbaldehyde CAS 876921-41-4

Description

The occurrence of 4H-benzo[b]imidazo[1,2-d][1,4]oxazine-6-carbaldehyde is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4H-benzo[b]imidazo[1,2-d][1,4]oxazine-6-carbaldehyde (CAS 876921-41-4), molecular formula C11H8N2O2 and molecular weight 200.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4H-benzo[b]imidazo[1,2-d][1,4]oxazine-6-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

As a certified reference material (CRM), 4H-benzo[b]imidazo[1,2-d][1,4]oxazine-6-carbaldehyde 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.
