Chemical Structure
Description
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.
1-[(5-sulfanyl-1,3,4-oxadiazol-2-yl)methyl]pyrrolidin-2-one (CAS 160758-18-9) is a high-purity analytical reference standard with the molecular formula C7H13N3O2S and a molecular weight of 203.26 g/mol.
1-[(5-sulfanyl-1,3,4-oxadiazol-2-yl)methyl]pyrrolidin-2-one (C7H13N3O2S) contains an amide group, a sulfone group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
