Chemical Structure
Description
The molecular framework of 2-(5,6-Dihydroimidazo[1,2-a]pyrazin-7(8h)-yl)propanoic acid (C9H13N3O2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2-(5,6-Dihydroimidazo[1,2-a]pyrazin-7(8h)-yl)propanoic acid (CAS 1270666-82-4) is a high-purity analytical reference standard with the molecular formula C9H13N3O2 and a molecular weight of 195.22 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.
