3-(5-amino-3-methyl-1H-pyrazol-1-yl)benzoic acid (CAS 872407-85-7), molecular formula C11H11N3O2 and molecular weight 217.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(5-amino-3-methyl-1H-pyrazol-1-yl)benzoic acid (C11H11N3O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
