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.
CATO supplies 5-(2-aminoethyl)-2,3-dihydro-1,3,4-oxadiazole-2-thione hydrochloride (CAS 139601-75-5), a certified reference material (molecular formula C4H7N3OSHCl, MW 181.64 g/mol) for analytical method development and quality control.
5-(2-aminoethyl)-2,3-dihydro-1,3,4-oxadiazole-2-thione hydrochloride (C4H7N3OSHCl) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
