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-(2-Bromophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(2-methyl-4-nitrophenyl)propanamide (CAS 332154-89-9) is a high-purity analytical reference standard with the molecular formula C18H15BrN4O4S and a molecular weight of 463.31 g/mol.
The molecular framework of 2-((5-(2-Bromophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(2-methyl-4-nitrophenyl)propanamide (C18H15BrN4O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
