CATO supplies 2-(3-Methyl-4-nitro-1h-pyrazol-1-yl)propanoic acid (CAS 956950-97-3), a certified reference material (molecular formula C7H9N3O4, MW 199.16 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Methyl-4-nitro-1h-pyrazol-1-yl)propanoic acid (C7H9N3O4) is characterized by an amino-acid-derived structure, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
