What is Vat Brown 3 (131-92-0) used for?

Vat Brown 3 is an odorless brown to dark brown powder that is a type of vat dye. It is insoluble in water and ethanol but slightly soluble in xylene for bordeaux red solution. In concentrated sulfuric acid, it forms a dark wine red color, which dilutes to a red light brown with flocks. Alkaline reduction leuco body results in a red color, while acid reduction leuco produces a yellow brown color. Vat Brown 3 is a light brittle dye with poor affinity to cotton, making it less used in cotton dyeing.InChI:InChI=1/C42H23N3O6/c46-37-24-14-7-8-15-25(24)38(47)34-33(37)30(44-42(51)22-12-5-2-6-13-22)20-28-23-18-19-27-32(35(23)45-36(28)34)40(49)26-16-9-17-29(31(26)39(27)48)43-41(50)21-10-3-1-4-11-21/h1-20,45H,(H,43,50)(H,44,51)
