Picoline
From Wikipedia, the free encyclopedia
Picoline refers to three different methylpyridine isomers, all with the chemical formula C6H7N and a molar mass of 93.13 g mol−1. All three are colourless liquids at room temperature and pressure.
The three compounds are:
- 2-Methylpyridine, α-picoline or ortho-picoline, CAS registry number [109-06-8]
- 3-Methylpyridine, β-picoline or meta-picoline, CAS RN [108-99-6]
- 4-Methylpyridine, γ-picoline or para-picoline, CAS RN [108-89-4]
The CAS number of an unspecified picoline isomer is [1333-41-1]
