Chemical Structure

3,5-Dimethyl-1-phenyl-1h-pyrazol-4-amine CAS 21683-30-7 chemical structure

Description

CATO supplies 3,5-Dimethyl-1-phenyl-1h-pyrazol-4-amine (CAS 21683-30-7), a certified reference material (molecular formula C11H13N3, MW 187.24 g/mol) for analytical method development and quality control.

The molecular framework of 3,5-Dimethyl-1-phenyl-1h-pyrazol-4-amine (C11H13N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 3,5-Dimethyl-1-phenyl-1h-pyrazol-4-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.
