Chemical Structure
Description
The molecular framework of n-(3-Aminophenyl)-1-ethyl-1h-pyrazole-5-carboxamide hydrochloride (C12H14N4OHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
n-(3-Aminophenyl)-1-ethyl-1h-pyrazole-5-carboxamide hydrochloride (CAS 1185069-63-9), molecular formula C12H14N4OHCl and molecular weight 266.73 g/mol, is a CATO reference standard with documented purity and traceability.
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), n-(3-Aminophenyl)-1-ethyl-1h-pyrazole-5-carboxamide hydrochloride 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.
