I have several simple dye synthesis for you to review and comment for safety and practicality. The dyes are mostly anthraquinone dyes, and the basics of the synthesis methodology is mostly described in expired patents. The precursors are mostly stock precursors with CAS numbers. The synthesis methods are mostly simple 1 and 2 step methods. The precursor chemicals have a significant cost, which is why we want you to review them first. The next project will be to actually synthesize the dyes, with another freelancer project.
