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 2-(benzyloxy)-1-oxo-2,6-diazaspiro[3.5]nonane-6-carboxylate.
tert-Butyl 2-(benzyloxy)-1-oxo-2,6-diazaspiro[3.5]nonane-6-carboxylate (CAS 1799438-99-5), molecular formula C19H26N2O4 and molecular weight 346.42 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl 2-(benzyloxy)-1-oxo-2,6-diazaspiro[3.5]nonane-6-carboxylate (C19H26N2O4) contains a flavonoid core, 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).
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.
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.
