Description
CATO supplies 3-(Methylthio)-1-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)propan-1-amine oxalate (CAS 1820639-45-9), a certified reference material (molecular formula C11H14N4OSC2H2O4, MW 340.35 g/mol) for analytical method development and quality control.
3-(Methylthio)-1-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)propan-1-amine oxalate (C11H14N4OSC2H2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).
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.
