U+9170 "酰" CJK Unified Ideograph-# Unicode Character

U+9170 "酰" CJK Unified Ideograph-# is a Chinese character that primarily signifies a chemical compound, specifically a type of acyl group or acid radical, often used in organic chemistry to denote the radical derived from an acid, such as acetic acid. This ideograph, composed of the semantic radical for "wine" or "fermented liquid" on the left and the phonetic component "先" on the right, appears in modern Chinese technical terminology, including compound words like "酰氯" for acyl chloride and "酰胺" for amide. Its usage is thus specialized, serving as a key component in the written language of chemistry rather than in everyday vocabulary.
