3,4-dihydroxy-3-cyclobutene-1,2-dione

We are engaged in manufacturing, exporting and supplying excellent quality 3,4-Dihydroxy-3-cyclobutene-1,2-dione to our valuable clients. Also known as the square acid, funk acid, 3,4-dihydroxy-3-cyclobutene-1,2-dione. Melting point> 300 a (293 a decomposition). White granular crystals, with strongly acidic, its pKl = 1.5; pK2 = 3.5. Ferric chloride aqueous solution and produce a deep purple. It may be bromine and potassium permanganate oxidation, and phenylhydrazine no response. With a carboxylic acid similar nature, may form salts with bases, can produce an ester, acid chlorides, amides and mixed anhydride. It can be used as acylating agent, and Fu activated aromatic acylation reaction. And an active double bond, methyl lively reaction to produce new compounds with specific properties. With 1,1,2,2-tetrafluoro-3,3,4,4-tetrachloro cyclobutane or full-chloro-1,3-butadiene as raw materials. For synthetic organic photoconductor, liquid crystal display materials, laser writing and recording material electrophotographic photoreceptors material intermediates.
