Applications
4-Methylpyridine is a classic pyridine heterocyclic fine chemical intermediate. It can undergo oxidation, amination, substitution and condensation reactions, widely used for synthesizing various substituted pyridine derivatives.
It is mainly used as raw material for pharmaceutical intermediates, agrochemical fungicides, herbicides and insecticide intermediates. Also applied in the production of feed additives, dye intermediates, resin curing agents, chemical analytical reagents and organic synthesis solvents.
Safety Information
Flammable liquid; irritating to skin, eyes and respiratory tract. Skin contact may cause irritation and dryness; liquid splashing into eyes causes severe stinging and congestion, rinse immediately with plenty of running water. Inhalation of vapor may cause throat discomfort, dizziness and respiratory irritation. Ingestion leads to gastrointestinal nausea and abdominal pain.
