Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[(2E)-2-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-methylhydrazin-1-ylidene}ethyl]-9,10-dihydroanthracene-9,10-dione.
CATO supplies 2-[(2E)-2-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-methylhydrazin-1-ylidene}ethyl]-9,10-dihydroanthracene-9,10-dione (CAS 338961-95-8), a certified reference material (molecular formula C23H15ClF3N3O2, MW 457.83 g/mol) for analytical method development and quality control.
Based on its molecular formula C23H15ClF3N3O2, 2-[(2E)-2-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-methylhydrazin-1-ylidene}ethyl]-9,10-dihydroanthracene-9,10-dione contains a steroid core, an amide 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 457.83 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.
