Description
CATO manufactures 3-Chloro-2-(3-chloro-4-methylphenyl)-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.
3-Chloro-2-(3-chloro-4-methylphenyl)-2h,4h,5h,6h-cyclopenta[c]pyrazole (CAS 1481510-25-1) is a high-purity analytical reference standard with the molecular formula C13H12Cl2N2 and a molecular weight of 267.15 g/mol.
3-Chloro-2-(3-chloro-4-methylphenyl)-2h,4h,5h,6h-cyclopenta[c]pyrazole (C13H12Cl2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
