Chemical Structure
Description
The molecular framework of 6-(Ethoxycarbonyl)-5,7-dimethylpyrazolo[1,5-a]pyrimidine-2-carboxylic acid (C12H13N3O4) 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).
6-(Ethoxycarbonyl)-5,7-dimethylpyrazolo[1,5-a]pyrimidine-2-carboxylic acid (CAS 312708-27-3) is a high-purity analytical reference standard with the molecular formula C12H13N3O4 and a molecular weight of 263.25 g/mol.
