Ethyl 4-hydroxypyrazolo[1,5-a]pyridine-3-carboxylate CAS 55899-22-4

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ethyl 4-hydroxypyrazolo[1,5-a]pyridine-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
