Chemical Structure
Description
Methyl 4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-2-carboxylate (CAS 307307-82-0) is a high-purity analytical reference standard with the molecular formula C9H12N2O2 and a molecular weight of 180.20 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Methyl 4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.20 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Methyl 4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
