Chemical Structure
Description
Structurally, N-(5-(bis(2-methoxyethyl)amino)-2-((5-nitrobenzo[c]isothiazol-3-yl)diazenyl)phenyl)acetamide (C21H24N6O5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 472.52 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
N-(5-(bis(2-methoxyethyl)amino)-2-((5-nitrobenzo[c]isothiazol-3-yl)diazenyl)phenyl)acetamide (CAS 105076-77-5) is a high-purity analytical reference standard with the molecular formula C21H24N6O5S and a molecular weight of 472.52 g/mol.
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.
