U+6C30 "氰" CJK Unified Ideograph-# is a Chinese character (漢字) that represents the chemical term for cyanogen (CN)2, a toxic gas, and more commonly refers to the cyanide group (CN) in compounds, often used in words like 氰化物 (cyanide) or 氰酸 (cyanic acid). It is composed of the radical 气 (qi, meaning gas or air) on the left, indicating its association with gaseous substances, and the phonetic component 青 (qing, meaning blue or green) on the right, which also contributes to its pronunciation. This character is primarily used in modern Chinese, Japanese, and Korean contexts for scientific and chemical terminology, and it appears in the Unicode Standard under the CJK (Chinese, Japanese, and Korean) Unified Ideographs block, with its official reading in Mandarin Chinese being qíng. Despite its niche usage, 氰 plays a crucial role in accurately naming hazardous and industrially important cyanide-based chemicals across East Asian languages.
