U+5DF0 "巰" CJK Unified Ideograph-# Unicode Character

U+5DF0 "巰" CJK Unified Ideograph-# is a rare Chinese character used in specialized or historical contexts, primarily recognized for its chemical meaning, where it denotes a mercapto or thiol group (sulfur-containing compound) in organic chemistry terminology. This character is composed of two radicals: the "巠" component related to threads or classics and the "气" radical associated with air or gas, reflecting its technical application in compound naming.
