Tagdiwala, P. V.; Rangnekar, D. W. published the artcile< Studies on novel pigments>, Formula: C8H4ClN3O2, the main research area is nitroquinoxaline derivative pigment ink; paint pigment nitroquinoxaline derivative.
The reaction of 2-chloro-6-nitroquinoxaline(I) with hydrazine gave 1,2-bis(6-nitroquinoxalin-2-yl)hydrazine (II) [95758-19-3] in 71.4% yield for use as red pigment in printing ink and paint. Similarly the reaction of I with piperazine yielded bright yellow 1,4-bis(6-nitroquinoxalin-2-yl)piperazine (III) [95758-20-6]. Fastness of the pigments to various agents was satisfactory; however, both pigments showed poor fastness when treated with DOP plasticizer. The oil absorption value of II and III was low compared to the com. standard pigments of similar shades.
Paintindia published new progress about Castor oil Role: PRP (Properties). 6272-25-9 belongs to class quinoxaline, and the molecular formula is C8H4ClN3O2, Formula: C8H4ClN3O2.
