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-(5-Nitrofuran-2-yl)-1-phenyl-1H-pyrazole-4-carboxamide (CAS 61620-82-4), molecular formula C14H10N4O4 and molecular weight 298.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(5-Nitrofuran-2-yl)-1-phenyl-1H-pyrazole-4-carboxamide (C14H10N4O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
