Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-NAphthalenesulfonic acid, 6-[2-(2,4-diaminophenyl)diazenyl]-3-[2-[4-[2-[4-[[7-[2-(2,4-diaminophenyl)diazenyl]-1-hydroxy-3-sulfo-2-naphthalenyl]diazenyl]phenyl]amino]-3-sulfophenyl]diazenyl]-4-hydroxy- is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1018.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-NAphthalenesulfonic acid, 6-[2-(2,4-diaminophenyl)diazenyl]-3-[2-[4-[2-[4-[[7-[2-(2,4-diaminophenyl)diazenyl]-1-hydroxy-3-sulfo-2-naphthalenyl]diazenyl]phenyl]amino]-3-sulfophenyl]diazenyl]-4-hydroxy- (CAS 76186-07-7), molecular formula C44H35N13O11S3 and molecular weight 1018.02 g/mol, is a CATO reference standard with documented purity and traceability.
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.
