1,4-Dibromobutane
1,4-Dibromobutane (CAS: 110-52-1) is a colorless to light yellow liquid dihalide used as a four-carbon alkylating and linking agent. It is a key intermediate for pharmaceuticals, agrochemicals, and specialty chemicals, enabling the construction of pyrrolidines, cyclopentane derivatives, and other cyclic structures through double substitution chemistry. It also serves as a building block for quaternary ammonium compounds, phase-transfer catalysts, and functional polymers where a flexible C4 spacer is needed. The liquid is stable under normal conditions and is typically stored and shipped in standard drum packaging. Customers choose it where a bifunctional bromide with predictable, stepwise reactivity is required in synthesis.
• Ring construction: double alkylation builds pyrrolidines, cyclopentanes, and heterocycles used in drug and agro synthesis.
• Pharmaceutical intermediates: a C4 linker for active ingredients and specialty amine compounds.
• Quaternary compounds: a precursor for bis-quaternary ammonium salts and phase-transfer catalysts used in synthesis.
• Polymer chemistry: used as a crosslinking and functionalization agent for resins and membrane materials.
