Chemical Structure
Description
CATO supplies 9,9'-(Sulfonylbis(4,1-phenylene))bis(3,6-dimethoxy-9H-carbazole) (CAS 1477507-77-9), a certified reference material (molecular formula C40H32N2O6S, MW 668.76 g/mol) for analytical method development and quality control.
Structurally, 9,9'-(Sulfonylbis(4,1-phenylene))bis(3,6-dimethoxy-9H-carbazole) (C40H32N2O6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 26.0, corresponding to approximately 26 ring(s) or double-bond equivalent(s). With a molecular weight of 668.76 g/mol, it falls into the 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).
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.
