Chemical Structure
Description
As a certified reference material (CRM), 4-Ethyl-3-(3-iodophenyl)-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.
4-Ethyl-3-(3-iodophenyl)-1h-pyrazol-5-amine (CAS 1187561-57-4) is a high-purity analytical reference standard with the molecular formula C11H12IN3 and a molecular weight of 313.14 g/mol.
The molecular framework of 4-Ethyl-3-(3-iodophenyl)-1h-pyrazol-5-amine (C11H12IN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. 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.
