C.I.Solubilised Vat Yellow 1,C.I.70601,CAS 6487-09-8,616.53,C28H14N2Na2O8S2

Molecular Formula:C₂₈H₁₄N₂Na₂O₈S₂

Molecular Weight: 616.53

CAS Registry Number:6487-09-8

Manufacturing Methods : (a) in the presence of pyridine, treated with chlorosulfonic acid C.I. Vat Yellow 1  leuco;
(b) in pyridine using metals (such as copper, iron, zinc, etc.) and sulfur trioxide source (such as sulfur trioxide, chlorosulfonic acid or chlorosulfonic acid ester, etc.) processing C.I. Vat Yellow 1 . In both cases, go through the addition of a base, insolubles were filtered off, the pyridine was removed, and the salting out into the line.
