Dodecyl Trimethy Lammonium Bromide
Aqueous Solubility: Demonstrates high water solubility, producing clear transparent solutions suitable for diverse aqueous-based applications.
Alkaline Characteristics: Forms weakly basic aqueous solutions with pH values typically ranging from 8 to 9, ideal for specific chemical processes requiring mild alkaline conditions.
Hygroscopic Nature: Exhibits moisture-absorbing properties that can be effectively managed through proper storage and handling protocols to maintain consistent performance.
Crystalline Structure: Presents as colorless crystals in pure form, offering both visual purity and physical stability for processing and storage requirements.
Dodecyltrimethylammonium bromide presents as a white or near-white crystalline powder or solid. In its purified state, the compound forms colorless crystals that exhibit a hygroscopic nature, readily absorbing atmospheric moisture. It demonstrates high aqueous solubility, forming transparent solutions when dissolved in water. The resulting aqueous medium displays weakly alkaline characteristics with pH values typically ranging between 8 and 9, attributable to hydrolytic dissociation of the quaternary ammonium groups.

(1-Dodecyl)trimethylammonium bromide functions as a versatile cationic surfactant and effective emulsifier for rubber and asphalt applications, while also serving as an antistatic agent for synthetic fibers. As an ionic surfactant, it demonstrates particular utility in the preparation of gold nanoparticles through synergistic combination with sodium dodecylsulfate. Additional industrial applications include its use in coating removal formulations and foam stabilization processes. The compound further enables the investigation of micellization behavior in water-dimethylsulfoxide mixed solvents through multiple analytical techniques including conductimetry, density measurements, and small-angle neutron scattering. It also represents a significant biochemical reagent for advanced proteomic studies.
