U+781C "砜" CJK Unified Ideograph-# Unicode Character

U+781C "砜" CJK Unified Ideograph-# is a Chinese character used in modern and classical Chinese writing, where its primary meaning relates to a type of chemical compound, specifically a sulfone, which is an organic sulfur compound containing a sulfonyl group bonded to two carbon atoms. The character is composed of a "stone" radical on the left, indicating its connection to mineral or chemical substances, and a phonetic component on the right that hints at its pronunciation, which in Mandarin is "fēng." Although less common in everyday vocabulary, "砜" appears in scientific and technical contexts, particularly in chemistry, where it denotes compounds used in pharmaceuticals and industrial applications, such as in the production of certain antibiotics or high-performance polymers like polysulfones. This character thus bridges traditional character construction with modern scientific nomenclature, reflecting the adaptability of the Chinese writing system.
