2-[4-(5-Methyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H,9H-pyrimido[1,6-a]azepin-2-yl]-N-(5-methyl-1,2-oxazol-3-yl)acetamide CAS 1775346-41-2 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.

CATO supplies 2-[4-(5-Methyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H,9H-pyrimido[1,6-a]azepin-2-yl]-N-(5-methyl-1,2-oxazol-3-yl)acetamide (CAS 1775346-41-2), a certified reference material (molecular formula C18H20N6O5, MW 400.39 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 2-[4-(5-Methyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H,9H-pyrimido[1,6-a]azepin-2-yl]-N-(5-methyl-1,2-oxazol-3-yl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 400.39 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).

As a certified reference material (CRM), 2-[4-(5-Methyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H,9H-pyrimido[1,6-a]azepin-2-yl]-N-(5-methyl-1,2-oxazol-3-yl)acetamide 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.
