Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N1-Allyl-N2-(2-(o-tolyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-yl)oxalamide (CAS 899993-75-0), a certified reference material (molecular formula C17H18N4O2S, MW 342.42 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N1-Allyl-N2-(2-(o-tolyl)-2,6-dihydro-4H-thieno[3,4-c]pyrazol-3-yl)oxalamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
