Description
5-Bromo-2-hydroxy-3-methoxybenzaldehyde may be employed for the following syntheses:ailanthoidol, via Stille coupling6-bromo-8-methoxy-3-(methoxycarbonyl)-2H-chromen-2-onebenzimidazole-based ligand, 2-(1H-benzoimidazol-2-yl)-4-bromo-6-methoxy-phenol (HL)chromogenic reagent, 5-bromo-2-hydroxy-3-methoxybenzaldehyde-p-hydroxy benzoic hydrazone(E)-N-(5-bromo-2-hydroxy-3-methoxybenzylidene)-2-hydroxybenzohydrazide monohydrate
Application
5-Bromo-2-hydroxy-3-methoxybenzaldehyde serves as a versatile building block in medicinal chemistry and heterocyclic synthesis. Its ortho-hydroxy and methoxy substituents enable facile derivatization via Ullmann or Suzuki coupling, while the aldehyde group supports reductive amination, imine formation, and cyclization reactions. Bench-stable and amenable to standard purification methods, it functions reliably in multi-step sequences requiring functional group compatibility and regiocontrol.
