Cas no 2044704-53-0 (4-Chloropyrazolo[1,5-a]pyridine-2-carboxylic acid)
4-Chloropyrazolo[1,5-a]pyridine-2-carboxylic acid is a heterocyclic compound featuring a pyrazolo[1,5-a]pyridine core substituted with a chlorine atom at the 4-position and a carboxylic acid group at the 2-position. This structure makes it a versatile intermediate in pharmaceutical and agrochemical synthesis, particularly for constructing biologically active molecules. The chlorine substituent enhances reactivity for further functionalization, while the carboxylic acid group allows for derivatization via esterification, amidation, or other coupling reactions. Its rigid fused-ring system contributes to stability and potential binding affinity in target applications. The compound is typically handled under controlled conditions due to its reactive functional groups.
