Part of speech: noun

Definitions

1. A colorless, oily organic compound, a methyl derivative of piperidine, used as a chemical intermediate and solvent
2. An alkaloid-type heterocyclic amine, a methylated form of piperidine, employed in the manufacture of other chemicals

Etymology: Pipecoline is a chemical name built from pieces of older chemical names, not from a single root. It is a methyl derivative of piperidine, a six-membered ring containing nitrogen. The "pipe-" comes from piperidine, which the Scottish chemist Thomas Anderson named around 1850 after piperine, the compound that gives black pepper its heat. That name traces back to Latin "piper," meaning pepper, which in turn came from Sanskrit "pippali." The "-coline" ending follows the pattern of picoline, a methylpyridine that Anderson had earlier isolated from coal tar and bone oil in the 1840s. Its first part echoes Latin "pix," meaning pitch, a nod to the tarry sources it came from. Chemists formed pipecoline by analogy with picoline, combining the piperidine stem with that suffix. The name is a systematic pattern in chemistry rather than an everyday word with a colorful backstory.
