Description

1,12-Dibromododecane (CAS No. 3344-70-5) is a high-purity, linear aliphatic dibromide with the molecular formula C₁₂H₂₄Br₂. This compound is characterized by its two terminal bromine atoms, making it a versatile bifunctional alkylating agent for organic synthesis and polymer chemistry. It is commonly employed as a key intermediate in the preparation of specialty chemicals, surfactants, and phase-transfer catalysts. With a molecular weight of 328.13 g/mol, it appears as a colorless to pale yellow liquid or low-melting solid under standard conditions. Our product is rigorously tested for purity (typically ≥95-98% by GC) and is supplied with detailed analytical documentation, including ¹H NMR and GC-MS data. Suitable for use in controlled environments, it should be stored in amber glass containers under inert atmosphere at 2-8°C to prevent degradation.
