Ethyl 5-(4-((1,4-dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)-5-oxopentanoate CAS 898782-07-5 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-(4-((1,4-dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)-5-oxopentanoate.

Ethyl 5-(4-((1,4-dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)-5-oxopentanoate (CAS 898782-07-5), molecular formula C21H29NO5 and molecular weight 375.46 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 5-(4-((1,4-dioxa-8-azaspiro[4.5]Decan-8-yl)methyl)phenyl)-5-oxopentanoate (C21H29NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
