Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-[3-Chloro-5-(trifluoromethyl)-2-pyridinyl]-4-methoxy-N-methylbenzenesulfonohydrazide.
CATO supplies N-[3-Chloro-5-(trifluoromethyl)-2-pyridinyl]-4-methoxy-N-methylbenzenesulfonohydrazide (CAS 339276-30-1), a certified reference material (molecular formula C14H13ClF3N3O3S, MW 395.78 g/mol) for analytical method development and quality control.
N-[3-Chloro-5-(trifluoromethyl)-2-pyridinyl]-4-methoxy-N-methylbenzenesulfonohydrazide (C14H13ClF3N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
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.
