Property and Stability of 3-Methylpyridine Powder

1. Chemical property is similar to pyridine, it is alkaline and can generate salt with inorganic acid and organic acid. It can form addition compounds with inorganic salts and halogenated alkanes. When hydrogenated, it can produce 3-methylpiperidine or pyridine depending on the reaction conditions. When oxidized, it produces pyridine-3-carboxylic acid (nicotinic acid, C5H4N-CO2H) or pyridine.
2.  Health hazard Invasion route: inhalation, ingestion, transdermal absorption. Health hazard: Exposure to this product may cause fatigue, general weakness, drowsiness, etc. In severe cases, neurological symptoms, such as unsteady gait, transient loss of consciousness, etc.　Toxicological information and environmental behavior Toxicity: It is a low toxicity category.
