2-(2-Chlorophenyl)-6,7-dihydropyrazolo[1,5-a]pyrazin-4(5H)-one CAS 1557293-41-0

Description

Compared with other compounds in its class, the molecular weight of 247.68 g/mol gives 2-(2-Chlorophenyl)-6,7-dihydropyrazolo[1,5-a]pyrazin-4(5H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2-Chlorophenyl)-6,7-dihydropyrazolo[1,5-a]pyrazin-4(5H)-one (CAS 1557293-41-0) is a high-purity analytical reference standard with the molecular formula C12H10ClN3O and a molecular weight of 247.68 g/mol.

2-(2-Chlorophenyl)-6,7-dihydropyrazolo[1,5-a]pyrazin-4(5H)-one (C12H10ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
