Product Description
3,6-Dibromopyridazine is a brominated nitrogen-containing heterocyclic compound with the molecular formula C₄H₂Br₂N₂ and a molecular weight of 237.88 g/mol. It features two bromine substituents on the pyridazine ring, making it a useful building block for further chemical functionalization and the synthesis of structurally diverse heterocyclic derivatives.
According to available reference data, 3,6-Dibromopyridazine has a melting point of 116–117°C, an estimated boiling point of 327.5 ± 22.0°C, and a reported density of 2.2 ± 0.1 g/cm³. Its estimated vapor pressure is 0.0 ± 0.7 mmHg at 25°C, while the reported flash point is 151.9 ± 22.3°C. These values should be treated as reference data and verified against the supplier's technical documentation and test methods.
Due to its dibrominated pyridazine structure, this compound is particularly useful in organic synthesis, heterocyclic chemistry, and medicinal chemistry research. Its two bromine substituents provide opportunities for selected cross-coupling and substitution reactions, supporting the preparation of functionalized pyridazine derivatives and other nitrogen-containing organic compounds.
For proper storage, keep the product in a tightly sealed container in a cool, dry, and well-ventilated area. Protect it from moisture, excessive heat, and incompatible materials. Follow the supplier's Safety Data Sheet (SDS) for specific storage and handling recommendations.
