It has been isolated from the basic fraction of coal tar and from bone oil. Their chemical properties resemble those of pyridine, although the presence of the methyl groups may prohibit some of the more straightforward reactions. Lutidine is the trivial name used to describe the chemical compounds which are dimethyl derivatives of pyridine. The r,sisomer exists largely in the chair conformation with equatorial methyl groups. The achiral isomer is the predominant isomer produced in this reaction. It is derived from our pyridine chain and has different uses in the pharmaceutical industry.
