Compared with other compounds in its class, the molecular weight of 141.59 g/mol gives (2r,3r)-2-Aminobutane-1,3-diol hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2r,3r)-2-Aminobutane-1,3-diol hydrochloride (CAS 79474-65-0), molecular formula C4H11NO2HCl and molecular weight 141.59 g/mol, is a CATO reference standard with documented purity and traceability.
(2r,3r)-2-Aminobutane-1,3-diol hydrochloride (C4H11NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
