Chemical Structure
Description
1,3-Dioxo-octahydroimidazolidino[1,5-a]piperazine-7-carboxamide (CAS 1258639-45-0), molecular formula C7H10N4O3 and molecular weight 198.18 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Dioxo-octahydroimidazolidino[1,5-a]piperazine-7-carboxamide (C7H10N4O3) 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. 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.
