Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(Pyridin-2-yl)-1H-pyrazol-5-amine (CAS 92352-29-9), molecular formula C8H8N4 and molecular weight 160.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 3-(Pyridin-2-yl)-1H-pyrazol-5-amine 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.
