Chemical Structure
Description
Structurally, 1142210-76-1 4-(3-{2-[(tert-Butoxycarbonyl)(methyl)amino]-ethyl}-1,2,4-oxadiazol-5-yl)benzoic acid 9417AC C17H21N3O5 (C17H21N3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 347.37 g/mol, it falls into the moderately-high-molecular-weight range. 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).
1142210-76-1 4-(3-{2-[(tert-Butoxycarbonyl)(methyl)amino]-ethyl}-1,2,4-oxadiazol-5-yl)benzoic acid 9417AC C17H21N3O5 (CAS 1142210-76-1), molecular formula C17H21N3O5 and molecular weight 347.37 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
