Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-N-(3-((2,4-dichlorobenzyl)oxy)thiophen-2-yl)hydrazine-1-carboxamide.
CATO supplies 2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-N-(3-((2,4-dichlorobenzyl)oxy)thiophen-2-yl)hydrazine-1-carboxamide (CAS 303147-96-8), a certified reference material (molecular formula C18H12Cl3F3N4O2S, MW 511.73 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H12Cl3F3N4O2S, 2-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-N-(3-((2,4-dichlorobenzyl)oxy)thiophen-2-yl)hydrazine-1-carboxamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 511.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
