Chemical Structure
Description
1-{[2-(2H-1,3-Benzodioxol-5-yl)imidazo[1,2-a]pyridin-3-yl]methyl}piperidine-4-carboxylic acid (CAS 904814-29-5), molecular formula C21H21N3O4 and molecular weight 379.41 g/mol, is a CATO reference standard with documented purity and traceability.
1-{[2-(2H-1,3-Benzodioxol-5-yl)imidazo[1,2-a]pyridin-3-yl]methyl}piperidine-4-carboxylic acid (C21H21N3O4) contains a flavonoid core, 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. 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.
