Chemical Structure
Description
The occurrence of 1-(Pyridin-2-yl)-1h-pyrazol-5-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(Pyridin-2-yl)-1h-pyrazol-5-amine (CAS 89977-46-8) is a high-purity analytical reference standard with the molecular formula C8H8N4 and a molecular weight of 160.18 g/mol.
The molecular framework of 1-(Pyridin-2-yl)-1h-pyrazol-5-amine (C8H8N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
