Description

Compared with other compounds in its class, the molecular weight of 434.59 g/mol gives 11-((5-dimethylaminonaphthalene-1-sulfonyl) amino)undecanoic acid 75805-80-0 AR-1C0297 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

11-((5-dimethylaminonaphthalene-1-sulfonyl) amino)undecanoic acid 75805-80-0 AR-1C0297 (CAS 75805-80-0) is a high-purity analytical reference standard with the molecular formula C23H34N2O4S and a molecular weight of 434.59 g/mol.

11-((5-dimethylaminonaphthalene-1-sulfonyl) amino)undecanoic acid 75805-80-0 AR-1C0297 (C23H34N2O4S) 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).

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.
