Core Product Parameters:

1,4-Dichlorobutane, also known as tetramethylene dichloride, CAS: 110-56-5, has the molecular formula C4H8Cl2 and a molecular weight of 127.01. This compound is a colorless transparent liquid at room temperature and is an important dichloroalkane. Due to the presence of two chlorine atoms and a specific four-carbon chain structure, it exhibits high reactivity and selectivity, making it widely used as a pharmaceutical intermediate and organic synthesis building block.

Specifications and Quality Control:

We provide high-purity 1,4-dichlorobutane products, with a standard specification of ≥99.0% (GC). Through multi-stage distillation processes and strict quality control, our products feature low color, low moisture, and low impurity content. Each batch is analyzed via gas chromatography (GC) to ensure stable and reliable product quality, meeting diverse needs from laboratory research to industrial production.
