5-((2-Chlorobenzyl)thio)-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carbaldehyde (CAS 321533-90-8) is a high-purity analytical reference standard with the molecular formula C13H10ClF3N2OS and a molecular weight of 334.74 g/mol.
5-((2-Chlorobenzyl)thio)-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carbaldehyde (C13H10ClF3N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 5-((2-Chlorobenzyl)thio)-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carbaldehyde 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.
