Diethyl 3,3'-disulfanediyl(2r,2'r)-bis(2-aminopropanoate) CAS 583-89-1

Description

Compared with other compounds in its class, the molecular weight of 296.41 g/mol gives Diethyl 3,3'-disulfanediyl(2r,2'r)-bis(2-aminopropanoate) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diethyl 3,3'-disulfanediyl(2r,2'r)-bis(2-aminopropanoate) (CAS 583-89-1), molecular formula C10H20N2O4S2 and molecular weight 296.41 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Diethyl 3,3'-disulfanediyl(2r,2'r)-bis(2-aminopropanoate) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.41 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.

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.
