Chemical Structure
Description
The occurrence of 3-Ethoxy-2-methylimidazo[1,2-a]pyrazine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Ethoxy-2-methylimidazo[1,2-a]pyrazine (CAS 659726-97-3) is a high-purity analytical reference standard with the molecular formula C9H11N3O and a molecular weight of 177.20 g/mol.
The molecular framework of 3-Ethoxy-2-methylimidazo[1,2-a]pyrazine (C9H11N3O) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
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.
