Description
CATO supplies 2-Fluoro-5-nitrobenzoic acid 7304-32-7 AS00992 BUTTPARK 32\01-76 RARECHEM AL BO 0445 TIMTEC-BB SBB028509 (CAS 7304-32-7), a certified reference material (molecular formula C7H10FNO4, MW 191.16 g/mol) for analytical method development and quality control.
The molecular framework of 2-Fluoro-5-nitrobenzoic acid 7304-32-7 AS00992 BUTTPARK 32\01-76 RARECHEM AL BO 0445 TIMTEC-BB SBB028509 (C7H10FNO4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
