Product description:Light yellow powder, absorbing water after the formation of crystal water color deepened, slightly soluble in water to form a pale yellow to yellow solution. When water recrystallization, containing a molecular crystal water. 91.5 ℃ melting point (102 ℃). Benzene, recrystallization, excluding water of crystallization, melting point of 98 ~ 100 ℃ (117 ℃). Above the boiling point of 360 ℃. Soluble in ethanol, benzene, acetone, insoluble in petroleum ether. And iron, copper, cobalt, nickel and 2, 2 '- pyridine to form complexes, and Fe2 + form red complexes, using potassium permanganate oxidation to 2, 2' - 2 pyridyl - 3, 3 'dicarboxylic acid. Can be used for quantitative colorimetric reagent of copper, iron, and can be used as the use of cerium sulfate titration indicator of iron salts; Also can be used for dye of animal fiber.
