2-(2-(4-Fluorophenyl)-4-oxopyrazolo[1,5-a]pyrazin-5(4H)-yl)-N-hydroxyacetimidamide CAS 1255791-17-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-(4-Fluorophenyl)-4-oxopyrazolo[1,5-a]pyrazin-5(4H)-yl)-N-hydroxyacetimidamide.

2-(2-(4-Fluorophenyl)-4-oxopyrazolo[1,5-a]pyrazin-5(4H)-yl)-N-hydroxyacetimidamide (CAS 1255791-17-3), molecular formula C14H12FN5O2 and molecular weight 301.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H12FN5O2, 2-(2-(4-Fluorophenyl)-4-oxopyrazolo[1,5-a]pyrazin-5(4H)-yl)-N-hydroxyacetimidamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 301.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.

CATO manufactures 2-(2-(4-Fluorophenyl)-4-oxopyrazolo[1,5-a]pyrazin-5(4H)-yl)-N-hydroxyacetimidamide 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.
