Description
As a certified reference material (CRM), 2-[4-(5-Ethyl-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-(2-methoxyphenyl)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.
CATO supplies 2-[4-(5-Ethyl-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-(2-methoxyphenyl)acetamide (CAS 1775402-99-7), a certified reference material (molecular formula C22H25N5O5, MW 439.46 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-Ethyl-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-(2-methoxyphenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 439.46 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
