Chemical Structure
Description
The occurrence of 5-[(dimethylamino)methyl]-1,3,4-oxadiazole-2-thiol is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-[(dimethylamino)methyl]-1,3,4-oxadiazole-2-thiol (CAS 33083-43-1), a certified reference material (molecular formula C5H9N3OS, MW 159.21 g/mol) for analytical method development and quality control.
5-[(dimethylamino)methyl]-1,3,4-oxadiazole-2-thiol (C5H9N3OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
