1-(5-Chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-N-(3,4-dichlorophenyl)methanimine CAS 956205-85-9 chemical structure

Description

CATO manufactures 1-(5-Chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-N-(3,4-dichlorophenyl)methanimine 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.

1-(5-Chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-N-(3,4-dichlorophenyl)methanimine (CAS 956205-85-9) is a high-purity analytical reference standard with the molecular formula C12H7Cl3F3N3 and a molecular weight of 356.56 g/mol.

1-(5-Chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)-N-(3,4-dichlorophenyl)methanimine (C12H7Cl3F3N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
