U+5576 "啶" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
啶
U+5576 "啶" CJK Unified Ideograph-# is a Chinese character used in modern Mandarin and Japanese, primarily as a phonetic component in chemical terminology, where it represents a suffix for heterocyclic compounds such as pyrimidine. Its structure combines the mouth radical with the phonetic element "定," and in Chinese, it is pronounced as "dìng," while in Japanese, it is read as "tei" or "jō" in certain contexts. Beyond its specialized scientific usage, the character also appears in classical texts and given names, though its primary lexical function remains tied to technical transcription rather than everyday language.
