[4-[5-(4-Dimethylaminophenyl)-1,5-diphenyl-penta-2,4-dienylidene]-1-cyclohexa-2,5-dienylidene]-dimethyl-azanium trifluoromethanesulfonate CAS 100237-71-6

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.

[4-[5-(4-Dimethylaminophenyl)-1,5-diphenyl-penta-2,4-dienylidene]-1-cyclohexa-2,5-dienylidene]-dimethyl-azanium trifluoromethanesulfonate (CAS 100237-71-6), molecular formula C33H33N2CF3O3S and molecular weight 606.70 g/mol, is a CATO reference standard with documented purity and traceability.

[4-[5-(4-Dimethylaminophenyl)-1,5-diphenyl-penta-2,4-dienylidene]-1-cyclohexa-2,5-dienylidene]-dimethyl-azanium trifluoromethanesulfonate (C33H33N2CF3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
