1-Phenyl-1H-pyrazol-3-ylamine CAS 1128-56-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Phenyl-1H-pyrazol-3-ylamine.

1-Phenyl-1H-pyrazol-3-ylamine (CAS 1128-56-9), molecular formula C9H9N3 and molecular weight 159.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H9N3, 1-Phenyl-1H-pyrazol-3-ylamine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 159.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 1-Phenyl-1H-pyrazol-3-ylamine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
