Diethyl 4-oxo-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-2,5-dicarboxylate CAS 459157-16-5

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

Diethyl 4-oxo-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-2,5-dicarboxylate (CAS 459157-16-5) is a high-purity analytical reference standard with the molecular formula C13H16N2O5 and a molecular weight of 280.28 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Diethyl 4-oxo-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-2,5-dicarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.28 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).
