Chemical Structure
Description
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 6-(2-Hydroxyethyl)pyrazolo[1,5-a]pyrimidine-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-(2-Hydroxyethyl)pyrazolo[1,5-a]pyrimidine-2-carboxylic acid (CAS 712319-12-5), molecular formula C9H9N3O3 and molecular weight 207.19 g/mol, is a CATO reference standard with documented purity and traceability.
