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 7-(2-Methoxyethyl)-2,5,7-triazaspiro[3.4]octane-6,8-dione hydrochloride.
7-(2-Methoxyethyl)-2,5,7-triazaspiro[3.4]octane-6,8-dione hydrochloride (CAS 2443909-91-7), molecular formula C8H13N3O3HCl and molecular weight 235.67 g/mol, is a CATO reference standard with documented purity and traceability.
7-(2-Methoxyethyl)-2,5,7-triazaspiro[3.4]octane-6,8-dione hydrochloride (C8H13N3O3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
