It is one of several dimethyl-substituted derivatives of pyridine, all of which are referred to as lutidines. It is a colorless liquid with mildly basic properties and a pungent, noxious odor. The compound has few uses. It is produced industrially by extraction from coal tars.Shinkichi Shimizu Nanao Watanabe Toshiaki Kataoka Takayuki Shoji Nobuyuki Abe Sinji Morishita Hisao Ichimura Pyridine and Pyridine Derivatives 2007 10.1002/14356007.a22_399 Biodegradation The biodegradation of pyridines proceeds via multiple pathways.Biochemical Interpretation of Quantitative Structure-Activity Relationships (QSAR) for Biodegradation of N-Heterocycles: A Complementary Approach to Predict Biodegradability Philipp Bodo Hoff Malte Germa Florence Schink Bernhard Beimborn Dieter Mersch-Sundermann Volker Environmental Science & Technology 2007 41 4 1390–1398 10.1021/es061505d 17593747 2007EnST...41.1390P https://nbn-resolving.de/urn:nbn:de:bsz:352-opus-59540 Although pyridine is an excellent source of carbon, nitrogen, and energy for certain microorganisms, methylation significantly retards degradation of the pyridine ring.Sims G.
