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 2-(((1,4-dioxaspiro[4.4]nonan-2-yl)methyl)amino)-2-oxoacetate.
Ethyl 2-(((1,4-dioxaspiro[4.4]nonan-2-yl)methyl)amino)-2-oxoacetate (CAS 1206988-06-8) is a high-purity analytical reference standard with the molecular formula C12H19NO5 and a molecular weight of 257.28 g/mol.
Ethyl 2-(((1,4-dioxaspiro[4.4]nonan-2-yl)methyl)amino)-2-oxoacetate (C12H19NO5) 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.
