Chemical Structure
Description
As a certified reference material (CRM), N-(4-(5-Ethyl-1,3,4-oxadiazol-2-yl)phenyl)-2,3-dimethoxybenzamide 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.
N-(4-(5-Ethyl-1,3,4-oxadiazol-2-yl)phenyl)-2,3-dimethoxybenzamide (CAS 946275-80-5) is a high-purity analytical reference standard with the molecular formula C19H19N3O4 and a molecular weight of 353.37 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, N-(4-(5-Ethyl-1,3,4-oxadiazol-2-yl)phenyl)-2,3-dimethoxybenzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 353.37 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.
