Description
CATO supplies 4-{[(2-chlorophenyl)methyl]amino}-1-ethyl-1h-pyrazole-3-carboxylic acid (CAS 1006319-25-0), a certified reference material (molecular formula C13H14ClN3O2, MW 279.72 g/mol) for analytical method development and quality control.
The molecular framework of 4-{[(2-chlorophenyl)methyl]amino}-1-ethyl-1h-pyrazole-3-carboxylic acid (C13H14ClN3O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-{[(2-chlorophenyl)methyl]amino}-1-ethyl-1h-pyrazole-3-carboxylic acid 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.
