Description

1-(5-Aminopyridin-2-yl)-3,5-dimethyl-1H-pyrazole-4-carboxylic acid (CAS 955962-76-2), molecular formula C11H12N4O2 and molecular weight 232.24 g/mol, is a CATO reference standard with documented purity and traceability.

1-(5-Aminopyridin-2-yl)-3,5-dimethyl-1H-pyrazole-4-carboxylic acid (C11H12N4O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
