Chemical Structure
Description
CATO supplies 3-Chloro-2-[(E)-2-[(4-nitrophenyl)methylidene]hydrazin-1-yl]-5-(trifluoromethyl)pyridine (CAS 338795-26-9), a certified reference material (molecular formula C13H8ClF3N4O2, MW 344.68 g/mol) for analytical method development and quality control.
3-Chloro-2-[(E)-2-[(4-nitrophenyl)methylidene]hydrazin-1-yl]-5-(trifluoromethyl)pyridine (C13H8ClF3N4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 3-Chloro-2-[(E)-2-[(4-nitrophenyl)methylidene]hydrazin-1-yl]-5-(trifluoromethyl)pyridine 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.
