Import 5-Bromophthalide — Buy in Bulk from Supplier in China

5-bromophthalide (CAS 64169-67-5) is a brominated phthalide derivative with molecular formula C8H5BrO2 and molecular weight 233.03 g/mol. Hebei Hua-chem Group supplies this compound as a white to off-white crystalline powder with demonstrated solubility in organic solvents and stability under standard storage conditions. The brominated aromatic lactone structure positions this material as a reactive intermediate for downstream synthesis rather than a finished active ingredient.

The material is typically manufactured via bromination of phthalide or related ring-closure routes, with standard commercial grades targeting purity levels suitable for pharmaceutical and agrochemical intermediate applications. Typical specifications for this compound class include melting point ranges, HPLC purity minima, and specified limits for related substances and residual solvents. Standard packaging for such specialty brominated intermediates ranges from 25 kg fibre drums to 200 kg steel drums, depending on order volume and customer requirements, with moisture barrier liners to protect hygroscopic properties.

Primary buyers include pharmaceutical API manufacturers, agrochemical formulators, and specialty dye producers who require brominated building blocks for C-N and C-C coupling reactions. The compound serves as a precursor to phthalide-based bioactive molecules and fluorescent materials. For procurement from Hebei Hua-chem Group, buyers should confirm minimum order quantities, available packaging formats, and whether the material is supplied from stock or manufactured to order. The supplier's location in Dongguang County, Hebei Province, offers access to Tianjin Port for international shipment.
