Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(5-Methyl-1,3,4-oxadiazol-2-yl)ethanamine (CAS 781612-35-9) is a high-purity analytical reference standard with the molecular formula C5H9N3O and a molecular weight of 127.14 g/mol.
2-(5-Methyl-1,3,4-oxadiazol-2-yl)ethanamine (C5H9N3O) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
