U+55B9 "喹" CJK Unified Ideograph-# Unicode Character

U+55B9 "喹" CJK Unified Ideograph-# is a Chinese character used in written Chinese, Japanese, and Korean, though it is most commonly encountered in modern Chinese. It is a compound character that typically functions in transliterations, most notably as the second syllable in the chemical term "喹啉" (kuí lín), which is the Chinese word for quinoline, an aromatic organic compound.
