Chemical Structure
Description
3-{[3-(dimethylamino)propyl]amino}-1λ6-thiolane-1,1-dione dihydrochloride (CAS 1203372-93-3) is a high-purity analytical reference standard with the molecular formula C9H20N2O2SHCl and a molecular weight of 256.79 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3-{[3-(dimethylamino)propyl]amino}-1λ6-thiolane-1,1-dione dihydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
