Product Description
2-Bromo-5-hydroxypyrazine (CAS No. 374063-92-0), also known as 5-Bromo-2(1H)-pyrazinone or 2-Hydroxy-5-bromopyrazine, is a brominated nitrogen-containing heterocyclic compound. It has the molecular formula C₄H₃BrN₂O and a molecular weight of 174.983 g/mol.
This compound is typically supplied as a white to light-brown crystalline powder. Its molecular structure contains a bromine substituent and a hydroxyl group (which may exist in tautomeric equilibrium with the corresponding pyrazinone form), making it a useful heterocyclic building block for organic synthesis and pharmaceutical research. The bromine functionality provides opportunities for further molecular modification in selected synthetic pathways.
With a reported density of approximately 1.9 ± 0.1 g/cm³ and a melting point of around 115°C (with decomposition), 2-Bromo-5-hydroxypyrazine has characteristic physical properties relevant to material identification and quality control. Its reported boiling point and vapor pressure are estimated values and should be treated as reference data rather than confirmed experimental specifications.
