Preparation

(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.

Properties and Applications

red light yellow.
