Chemical Structure
Description
CATO supplies 2-(3,4-Dichlorophenyl)-4,5-dimethyl-2,3-dihydro-1h-pyrazol-3-imine (CAS 1356744-23-4), a certified reference material (molecular formula C11H11Cl2N3, MW 256.13 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3,4-Dichlorophenyl)-4,5-dimethyl-2,3-dihydro-1h-pyrazol-3-imine (C11H11Cl2N3) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-(3,4-Dichlorophenyl)-4,5-dimethyl-2,3-dihydro-1h-pyrazol-3-imine 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.
