88-99-3, Name is Pathalic acid, molecular formula is C8H6O4, Safety of Pathalic acid, belongs to phthalazine compound, is a common compound. In a patnet, author is Zhao, Xiao-Na, once mentioned the new application about 88-99-3.
A highly efficient and recyclable cobalt ferrite chitosan sulfonic acid magnetic nanoparticle for one-pot, four-component synthesis of 2H-indazolo[2,1-b]phthalazine-triones
A highly efficient magnetic CoFe2O4 chitosan sulfonic acid nanoparticle (CoFe2O4-CS-SO3H) was prepared and applied for one-pot, four-component synthesis of 2H-indazolo[2,1-b]phthalazine-triones by condensation of phthalic anhydride, hydrazinium hydroxide, 1,3-cyclohexanedione and aldehydes under solvent-free conditions at 80 degrees C. The magnetic nanocatalyst could be readily recovered by applying an external magnet and recycled several times without significant loss of its catalytic activity.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 88-99-3 help many people in the next few years. Safety of Pathalic acid.
