Description

Compared with other compounds in its class, the molecular weight of 211.22 g/mol gives 2-Phenylpyrazolo[1,5-a]pyrazin-4(5H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Phenylpyrazolo[1,5-a]pyrazin-4(5H)-one (CAS 1255784-04-3), molecular formula C12H9N3O and molecular weight 211.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Phenylpyrazolo[1,5-a]pyrazin-4(5H)-one (C12H9N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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