Pyridine in Bulk

Pyridine is a basic nitrogen heterocycle that acts as solvent, base and acid scavenger in one, which is why it appears throughout agrochemical and pharmaceutical synthesis. It mops up the hydrogen chloride generated in acylation and sulphonylation reactions while keeping everything in solution. BulkFineChem supplies industrial grade pyridine to agrochemical manufacturers, API producers and fine chemical units across India.

Specification

Purity and water content are stated on the batch Certificate of Analysis. Anhydrous grade is available where the reaction demands it.

• CAS No. 110-86-1
• HSN Code 29333100
• Purity 99 percent minimum
• Appearance: clear colourless to pale yellow liquid, strong unpleasant odour
• Packing: 200 kg MS drums

Applications

Because it is expensive relative to common solvents, pyridine is usually recovered and recycled in continuous processes.

• Base and acid scavenger in acylation and sulphonylation
• Intermediate in herbicide and insecticide manufacture
• Solvent and catalyst in API synthesis
• Precursor for pyridine derivatives and vitamin chemistry
• Denaturant in industrial alcohol

Safety, Handling and Compliance

Pyridine is flammable, toxic by several routes and has an exceptionally penetrating odour that persists on skin and clothing.

• Flash point around 20 degrees C; keep away from ignition sources
• Use only with effective local exhaust ventilation
• Hygroscopic; keep drums sealed to protect anhydrous grade
• Avoid contact with strong acids and oxidisers
• SDS issued on request

FAQs

Questions buyers commonly ask about pyridine.

• Is anhydrous grade available? Yes, specify your maximum water limit when enquiring.
• Can pyridine be recovered? Yes, most continuous processes distil and reuse it.
• Why is the odour so persistent? It is detectable at very low concentrations and absorbs into skin and fabric.
• Can I get a sample? Yes, trial quantities can be arranged.
• What documents are provided? GST invoice, batch CoA, SDS and TREM card.
