一般描述
碘是一种深灰色固体，会升华成紫色气体。对于固体，碘分子具有高蒸汽压（0.31 mmHg at 25 °C）化学上，碘是亲电的，可参与亲电取代反应，如碘化有机化合物。这种亲电行为是由于碘原子具有高电负性和较大的尺寸，这使得它成为相对弱的氧化剂。我们合成的高纯度碘含有少于100 ppm的痕量金属杂质。
应用
高纯度碘在制药、化学和电子工业领域有多种用途。在半导体和电子工业中，高纯度碘用于生产半导体，它作为掺杂剂制造p型半导体和LCD显示器。在生命科学行业，高纯度碘用于生产X-射线造影剂，它可增强医学成像时特定器官的可见度。碘还在各种医疗应用中被用作消毒剂、抗真菌剂和防腐剂。其独特的特性使其成为各种高科技应用中的重要元素，在这些应用中，其高纯度是必不可少的。
特点和优势
我们99.99%纯度的碘适用于制药，化学和电子工业，这些纯度最重要的领域。
