Chemical Structure
Description
The molecular framework of (R)-1-(Pyridin-2-yl)ethanamine (2S,3S)-2,3-dihydroxysuccinate (C4H6O6C7H10N2) is characterized by an amino-acid-derived structure, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(R)-1-(Pyridin-2-yl)ethanamine (2S,3S)-2,3-dihydroxysuccinate (CAS 1821811-36-2) is a high-purity analytical reference standard with the molecular formula C4H6O6C7H10N2 and a molecular weight of 272.26 g/mol.
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.
