3,4,5-trifluorobenzamide 3,4,5-tris(fluoranyl)benzamide 78324-75-1 A839393 CAS 78324-75-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,4,5-trifluorobenzamide 3,4,5-tris(fluoranyl)benzamide 78324-75-1 A839393 (CAS 78324-75-1), molecular formula C7H4F3NO and molecular weight 175.11 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4,5-trifluorobenzamide 3,4,5-tris(fluoranyl)benzamide 78324-75-1 A839393 (C7H4F3NO) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.

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.
