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 tert-Butyl 8-oxo-5-oxa-2-azaspiro[3.4]octane-2-carboxylate.
tert-Butyl 8-oxo-5-oxa-2-azaspiro[3.4]octane-2-carboxylate (CAS 1453315-97-3) is a high-purity analytical reference standard with the molecular formula C11H17NO4 and a molecular weight of 227.26 g/mol.
tert-Butyl 8-oxo-5-oxa-2-azaspiro[3.4]octane-2-carboxylate (C11H17NO4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
