Chemical Structure
Description
The occurrence of pyrazolo[1,5-a]pyridin-3-ol is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies pyrazolo[1,5-a]pyridin-3-ol (CAS 51118-68-4), a certified reference material (molecular formula C7H6N2O, MW 134.14 g/mol) for analytical method development and quality control.
Structurally, pyrazolo[1,5-a]pyridin-3-ol (C7H6N2O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 134.14 g/mol, it falls into the low-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
