Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Chloro-2-(4-chlorophenyl)-2h,4h,5h,6h-cyclopenta[c]pyrazole (CAS 1490558-04-7), a certified reference material (molecular formula C12H10Cl2N2, MW 253.13 g/mol) for analytical method development and quality control.
The molecular framework of 3-Chloro-2-(4-chlorophenyl)-2h,4h,5h,6h-cyclopenta[c]pyrazole (C12H10Cl2N2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 3-Chloro-2-(4-chlorophenyl)-2h,4h,5h,6h-cyclopenta[c]pyrazole 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.
