(2R,2'R)-3,3'-Disulfanediylbis(2-amino-3-methylbutanoic acid) CAS 113626-33-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,2'R)-3,3'-Disulfanediylbis(2-amino-3-methylbutanoic acid).

(2R,2'R)-3,3'-Disulfanediylbis(2-amino-3-methylbutanoic acid) (CAS 113626-33-8) is a high-purity analytical reference standard with the molecular formula C10H20N2O4S2 and a molecular weight of 296.41 g/mol.

The molecular framework of (2R,2'R)-3,3'-Disulfanediylbis(2-amino-3-methylbutanoic acid) (C10H20N2O4S2) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
