Chemical Structure
Description
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.
3-Cyclopropyl-1-(2,4,6-trichlorophenyl)-1H-pyrazol-5-amine (CAS 175137-50-5) is a high-purity analytical reference standard with the molecular formula C12H10Cl3N3 and a molecular weight of 302.59 g/mol.
The molecular framework of 3-Cyclopropyl-1-(2,4,6-trichlorophenyl)-1H-pyrazol-5-amine (C12H10Cl3N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 3-Cyclopropyl-1-(2,4,6-trichlorophenyl)-1H-pyrazol-5-amine 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.
