Description
As a certified reference material (CRM), 3-(1H-Indol-2-yl)-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.
3-(1H-Indol-2-yl)-1H-pyrazol-4-amine (CAS 784193-36-8), molecular formula C11H10N4 and molecular weight 198.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(1H-Indol-2-yl)-1H-pyrazol-4-amine (C11H10N4) 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 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.
