About
The character 苄 (biàn) is a modern phono-semantic compound created for translating Western organic chemistry terms. Its top portion, the grass radical 艹 (cǎo), historically used for plants, was adopted by chemists as the standard semantic indicator for aromatic compounds. The lower portion, 卞 (biàn), serves as a phonetic component approximating the first syllable of "benzyl". With no classical usage, 苄 strictly denotes the benzyl functional group, a benzene ring attached to a methylene group, and appears only in scientific literature and specific chemical compound names.
