Product Description of 2-Amino-3,5-dichloropyridine CAS#4214-74-8
2-Amino-3,5-dichloropyridine is a common pyridine-series organic compound with the molecular formula C₅H₄Cl₂N₂. The commercial-grade chemical appears as off-white to pale-beige crystalline powder. Its melting-point ranges from 78 °C to 83 °C, and it barely dissolves in water while showing good solubility in many organic solvents. Standard finished goods normally reach a minimum purity of 97.5% tested by HPLC detection. This stable aromatic intermediate is widely adopted for synthesising agro-chemicals, pharmaceutical raw-materials and fine-chemical products. It needs sealed preservation under cool and shaded surroundings, and operators shall avoid direct contact with its powder against skin-and-eye irritation.
