Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 5-oxo-1,2,3,5-tetrahydroimidazo[1,2-a]pyridine-8-carboxylate.
CATO supplies Ethyl 5-oxo-1,2,3,5-tetrahydroimidazo[1,2-a]pyridine-8-carboxylate (CAS 439118-88-4), a certified reference material (molecular formula C10H12N2O3, MW 208.21 g/mol) for analytical method development and quality control.
Ethyl 5-oxo-1,2,3,5-tetrahydroimidazo[1,2-a]pyridine-8-carboxylate (C10H12N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
