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 4-(1-Methyl-1H-pyrazol-4-yl)-1H-pyrazol-3-amine.
CATO supplies 4-(1-Methyl-1H-pyrazol-4-yl)-1H-pyrazol-3-amine (CAS 930286-91-2), a certified reference material (molecular formula C7H9N5, MW 163.18 g/mol) for analytical method development and quality control.
The molecular framework of 4-(1-Methyl-1H-pyrazol-4-yl)-1H-pyrazol-3-amine (C7H9N5) is characterized by a nitrile group, an aromatic ring system. 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(1-Methyl-1H-pyrazol-4-yl)-1H-pyrazol-3-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.
