Product Name:2,3,5,6-Tetrachloropyridine
English Name:2,3,5,6-Tetrachloropyridine
CAS No.:2402-79-1
Aliases:2,3,5,6-Tetrachloropyridine
Molecular Formula:C5HCl4N
Physical Properties:White to off-white crystalline powder. Melting point approximately 90–92°C, boiling point approximately 254°C, relative density 1.65 (20°C), flash point >110°C. Insoluble in water, readily soluble in ethanol, acetone, benzene, chloroform and other organic solvents. Stable under normal temperature and pressure; avoid contact with strong oxidants.
Uses:This product is an important fine chemical intermediate, mainly used in the synthesis of fluoropyridine pesticides (such as herbicides and insecticides) and pharmaceutical intermediates. It can be converted into 2,3,5,6-tetrafluoropyridine by fluorination for further synthesis of highly effective and low-toxicity pesticides; it is also used in the preparation of pyridine-based ligands and other specialty fine chemicals.
Technical Specifications:
Assay (GC) ≥98.0%
Appearance: white to off-white crystalline powder
Melting point: 89.0–93.0°C
Water content: ≤0.5%
Residue on ignition: ≤0.1%
