Chemical Structure
Description
3,3'-Disulfanediylbis(N-phenylpropanamide) (CAS 1047-89-8) is a high-purity analytical reference standard with the molecular formula C18H20N2O2S2 and a molecular weight of 360.49 g/mol.
Based on its molecular formula C18H20N2O2S2, 3,3'-Disulfanediylbis(N-phenylpropanamide) contains a steroid core, 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 360.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
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.
