Chemical Structure
Description
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Sodium 6-amino-4-hydroxy-3-((4-(phenyldiazenyl)naphthalen-1-yl)diazenyl)naphthalene-2-sulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 519.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Sodium 6-amino-4-hydroxy-3-((4-(phenyldiazenyl)naphthalen-1-yl)diazenyl)naphthalene-2-sulfonate (CAS 6227-04-9) is a high-purity analytical reference standard with the molecular formula C26H18N5O4SNa and a molecular weight of 519.51 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.
