3-[(2-aminoethyl)amino]pyrrolidine-2,5-dione dihydrochloride CAS 2059937-65-2

Description

Compared with other compounds in its class, the molecular weight of 193.63 g/mol gives 3-[(2-aminoethyl)amino]pyrrolidine-2,5-dione dihydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-[(2-aminoethyl)amino]pyrrolidine-2,5-dione dihydrochloride (CAS 2059937-65-2), molecular formula C6H11N3O2HCl and molecular weight 193.63 g/mol, is a CATO reference standard with documented purity and traceability.

3-[(2-aminoethyl)amino]pyrrolidine-2,5-dione dihydrochloride (C6H11N3O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

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.
