Chemical Structure
Description
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.
4-(4-Methylbenzoyl)-1-oxa-4-azaspiro[4.5]decane-3-carboxylic acid (CAS 1214025-94-1), molecular formula C17H21NO4 and molecular weight 303.35 g/mol, is a CATO reference standard with documented purity and traceability.
4-(4-Methylbenzoyl)-1-oxa-4-azaspiro[4.5]decane-3-carboxylic acid (C17H21NO4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
