How to Write 胩 (kǎ) — Meaning “isocyanide”

Think of a 'car' (卡 sounds like 'car') made of flesh (月) that emits weird fumes — this represents isocyanide, a toxic chemical group. The unusual image helps recall both the sound and the meaning.

Write the left radical 月 narrow and slightly taller. For the right part 卡, the top horizontal is short, then the vertical stroke goes down without touching the top horizontal too early, ending with a small bottom horizontal. A common mistake is making the 卡 part too wide or uneven.

胩 has 卡 inside, sounds kǎ, and means isocyanide. 朊 (ruǎn) uses 元 and means protein in biochemistry. 朋 (péng) is two 月 side by side and means friend. Visually, 胩 has a balanced left-right structure with a distinct vertical stroke in the right half.

胩 is a technical character found only in organic chemistry terms like 异胩 (isocyanide) and 胩基 (isocyano group). It is not used in daily life or general vocabulary; learners encounter it in scientific textbooks or specialized chemical discussions.

Common words containing 胩 include: 胩胺 (kǎ àn) — carbylamine; 异胩 (yì kǎ) — isocyanide; 胩基 (kǎ jī) — isocyano group.
