Chemical Structure
Description
(2R,3S)-2,3-Diaminobutanoic acid dihydrochloride (CAS 648922-13-8), molecular formula C4H10N2O2HCl and molecular weight 154.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2R,3S)-2,3-Diaminobutanoic acid dihydrochloride (C4H10N2O2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
