Chemical Structure
Description
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.
3-(Methylthio)-1-(3-(thiophen-2-yl)-1,2,4-oxadiazol-5-yl)propan-1-amine oxalate (CAS 1820649-57-7), molecular formula C10H13N3OS2C2H2O4 and molecular weight 345.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-(Methylthio)-1-(3-(thiophen-2-yl)-1,2,4-oxadiazol-5-yl)propan-1-amine oxalate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 345.39 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
