Chemical Structure
Description
2-Ethoxy-4-oxo-4,6,7,8,9,10-hexahydropyrido[1,2-a]azepine-1-carboxylic acid (CAS 1291844-45-5), molecular formula C13H17NO4 and molecular weight 251.28 g/mol, is a CATO reference standard with documented purity and traceability.
2-Ethoxy-4-oxo-4,6,7,8,9,10-hexahydropyrido[1,2-a]azepine-1-carboxylic acid (C13H17NO4) contains a nitrogen-containing heterocyclic scaffold, 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.
As a certified reference material (CRM), 2-Ethoxy-4-oxo-4,6,7,8,9,10-hexahydropyrido[1,2-a]azepine-1-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
