Chemical Structure
Description
Ethyl 2-Amino-4-(1-pyrazolyl)benzoate (C12H13N3O2) 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 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).
Ethyl 2-Amino-4-(1-pyrazolyl)benzoate (CAS 1375064-68-8), molecular formula C12H13N3O2 and molecular weight 231.25 g/mol, is a CATO reference standard with documented purity and traceability.
