Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies Ethyl (3E)-3-{2-[2,4-dichloro-5-(2-methoxyethoxy)phenyl]hydrazin-1-ylidene}-4,4,4-trifluorobutanoate (CAS 866136-37-0), a certified reference material (molecular formula C15H17Cl2F3N2O4, MW 417.21 g/mol) for analytical method development and quality control.
Ethyl (3E)-3-{2-[2,4-dichloro-5-(2-methoxyethoxy)phenyl]hydrazin-1-ylidene}-4,4,4-trifluorobutanoate (C15H17Cl2F3N2O4) 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.
