Chemical Structure
Description
The occurrence of 2-((5-(2-Bromophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(3-methoxy-4-nitrophenyl)acetamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-((5-(2-Bromophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(3-methoxy-4-nitrophenyl)acetamide (CAS 332154-91-3), a certified reference material (molecular formula C17H13BrN4O5S, MW 465.28 g/mol) for analytical method development and quality control.
The molecular framework of 2-((5-(2-Bromophenyl)-1,3,4-oxadiazol-2-yl)thio)-N-(3-methoxy-4-nitrophenyl)acetamide (C17H13BrN4O5S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
