Etymology of QUINOLDINE

The word quinoldine is derived from the chemical compound it represents, which is called quinoline. The term quinoline originated from the German word chinolin, which was introduced by the German chemist August Wilhelm von Hofmann in 1848. The German term chinolin was inspired by the Latin word China (meaning China) due to the compound's initial isolation from coal tar, which was known as China tar at the time. Quinoldine, on the other hand, is a derivative of quinoline and its name reflects the addition of the suffix -dine.
