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.
1-[6-(4-azido-2-nitro-anilino)hexanoyloxy]-2,5-dioxo-pyrrolidine-3-sulfonic acid (CAS 102568-43-4), molecular formula C16H24N6O9S and molecular weight 476.46 g/mol, is a CATO reference standard with documented purity and traceability.
1-[6-(4-azido-2-nitro-anilino)hexanoyloxy]-2,5-dioxo-pyrrolidine-3-sulfonic acid (C16H24N6O9S) contains a flavonoid core, an amide group, a sulfone 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).
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.
