能溶于醇、醚，水和苯，微溶于氯仿和乙酸。有毒，半数致死量(小鼠，腹腔)12.9mg/kg。有刺激性。有机合成原料。医药方面，用于合成维生素B1、氨蝶呤、氨苯蝶啶等一系列重要药物。染料方面、农药方面及其他方面都有重要的用途。也可用作金的萃取剂。中国现主要用于生产氨苯蝶啶、苄嘧黄隆、1,4,5,8-萘四甲酸、嘧啶系列产品。 丙二腈，一种弱氰基碳酸，是一种反应性超高的多功能化合物。这种结晶脂肪族腈可用作合成杂环化合物和聚合物的合成砌块 应用 丙二腈可用于：碱促进的[1,6]-萘啶水上合成；γ--酮酰胺的合成；特殊杂环药物支架（包括吡啶、1,4-二氢吡啶、苯并吡喃[2,3-b]吡啶和二氢-1,4-二噻吩骨架）的制备 Malononitrile, a weak cyanocarbon acid, is a versatile compound with exceptional reactivity, widely used in condensation reactions. Malononitrile may be used in the base-promoted on-water synthesis of [1,6]-naphthyridines; synthesis of γ-ketoamides;preparation of heterocyclic privileged medicinal scaffolds involving pyridine, 1,4-dihydropyridine, chromeno[2,3-b]pyridine and dihydro-1,4-dithiepine frameworks. Malonitrile, a weak cyanocarbonic acid, is a highly reactive multifunctional compound. This crystalline aliphatic nitrile can be used as a synthetic block for the synthesis of heterocyclic compounds and polymers
