1,4-Dibromobutane

1,4-Dibromobutane_110-52-1_High-Purity Organic Synthesis Intermediate

Core Product Parameters:

1,4-Dibromobutane (also known as Tetramethylene dibromide), CAS: 110-52-1, molecular formula C₄H₈Br₂, molecular weight 215.92. This product is a colorless to light yellow transparent liquid at room temperature and serves as an important dihaloalkane. Due to the presence of two reactive bromine atoms and a specific four-carbon chain structure, it exhibits high reactivity and is widely used as an organic synthesis intermediate and cyclization reagent.

Specifications and Quality Control:

We provide high-purity 1,4-dibromobutane with a standard specification of ≥99.0% (GC). Through multi-stage distillation processes and strict quality control, the product features low color, low moisture, low acid value, and low free bromine content. Each batch is analyzed by gas chromatography (GC) to ensure stable and reliable quality, meeting diverse needs from laboratory research to industrial production.

Main Application Fields:
