Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-Butyl-3-fluoro-N-(5-pyridin-4-yl-[1,3,4]-thiadiazol-2-yl)-benzamide (CAS 834892-59-0) is a high-purity analytical reference standard with the molecular formula C18H17FN4OS and a molecular weight of 356.42 g/mol.
N-Butyl-3-fluoro-N-(5-pyridin-4-yl-[1,3,4]-thiadiazol-2-yl)-benzamide (C18H17FN4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
