Chemical Structure
Description
CATO supplies 2,2'-Oxalylbis(N-phenylhydrazine-1-carbothioamide) (CAS 33371-71-0), a certified reference material (molecular formula C16H16N6O2S2, MW 388.47 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H16N6O2S2, 2,2'-Oxalylbis(N-phenylhydrazine-1-carbothioamide) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 388.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
