4-amino-1-ethyl-N-[(1-methyl-1H-pyrazol-4-yl)methyl]-1H-pyrazole-5-carboxamide,HCl CAS 1431963-65-3 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-amino-1-ethyl-N-[(1-methyl-1H-pyrazol-4-yl)methyl]-1H-pyrazole-5-carboxamide,HCl.

CATO supplies 4-amino-1-ethyl-N-[(1-methyl-1H-pyrazol-4-yl)methyl]-1H-pyrazole-5-carboxamide,HCl (CAS 1431963-65-3), a certified reference material (molecular formula C11H16N6OHCl, MW 284.75 g/mol) for analytical method development and quality control.

The molecular framework of 4-amino-1-ethyl-N-[(1-methyl-1H-pyrazol-4-yl)methyl]-1H-pyrazole-5-carboxamide,HCl (C11H16N6OHCl) 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 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 4-amino-1-ethyl-N-[(1-methyl-1H-pyrazol-4-yl)methyl]-1H-pyrazole-5-carboxamide,HCl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
