| Hazard Information | Back Directory | [General Description]
White, crystalline or flaky solid with an almond-like odor. Mp:161-2°C (sublimes) Density 1.28 g cm-3 (at 25°C). Insoluble in water. Soluble in benzene and in acetone. Used as an intermediate in the manufacture of polyurethane paints and varnishes, pharmaceuticals, and agricultural chemicals. | [Reactivity Profile]
m-PHTHALODINITRILE is a combustible solid. Emits toxic fumes of NOx and CN-when heated to decomposition. Incompatible with strong oxidizing agents. | [Description]
1,3-Dicyanobenzene appears as white, crystalline or flaky solid with an almond-like odor. mp: 161-162 °C (sublimes) Density 1.28 g/cm3 (at 25 °C). Insoluble in water. Soluble in benzene and in acetone. Used as an intermediate in the manufacture of polyurethane paints and varnishes, pharmaceuticals, and agricultural chemicals. | [Chemical Properties]
off-white to light brown solid | [Uses]
An intermediate in the manufacture of
paints, varnishes, and agricultural chemicals. | [Definition]
ChEBI: Isophthalonitrile is a nitrile. It is functionally related to an isophthalic acid. | [Health Hazard]
m-Phthalodinitrile is a skin
irritant in animals.In humans there have been no reports of
adverse effects. The probable reason for lack
of systemic effects is that aromatic, unlike
aliphatic, nitriles do not liberate cyanide in the
body. | [Flammability and Explosibility]
