In the realm of fine chemicals and organic synthesis, certain molecules stand out for their versatility and indispensable role in creating advanced materials and pharmaceuticals. 1,6-Dibromohexane (CAS: 629-03-8) is one such compound, prized for its dual functionality and utility as a robust building block. Understanding its characteristics and applications is essential for researchers and industrial buyers alike.

Chemical Identity and Properties
1,6-Dibromohexane, also known as hexamethylene dibromide, is an aliphatic dibromoalkane with the molecular formula C6H12Br2. Its structure features a six-carbon chain with bromine atoms situated at each terminus. This arrangement provides two reactive sites, making it an effective alkylating agent and a valuable intermediate in many synthetic routes. Typically presented as a colorless to pale yellow liquid, it possesses a density of approximately 1.586 g/mL and a relatively high boiling point of 243°C, indicating good thermal stability under controlled conditions.

Synthesis and Purity Standards
The production of 1,6-Dibromohexane commonly involves the bromination of 1,6-hexanediol, a straightforward reaction yielding the desired dibrominated product. The critical factor for its use in sophisticated applications is purity. Manufacturers strive to achieve assay levels of 99.0% or higher, as confirmed by Gas Chromatography (GC). This high purity is paramount, especially when the compound is used in pharmaceutical synthesis or the development of performance polymers, where even minor impurities can compromise the final product's efficacy and integrity.
