Dodecyltrimethylammonium Bromide (DTAB) is a chemical compound widely utilized for its properties as a cationic surfactant. Its characteristic white powder appearance and high purity, often assaying at 99%, make it a sought-after reagent in both industrial and research settings. Understanding its key properties and where to buy DTAB is crucial for any professional working with this versatile compound.

The molecular formula of DTAB, C15H34BrN, and its CAS number, 1119-94-4, precisely define this chemical entity. As a quaternary ammonium compound, DTAB exhibits excellent surface activity, enabling it to reduce surface tension and form micelles in aqueous solutions. Its hydrophilic head group, the trimethylammonium cation, imparts its cationic nature, while the hydrophobic dodecyl tail provides solubility in non-polar environments. This dual nature is fundamental to its functionality as an emulsifier, dispersant, and solubilizing agent.

The typical specification for DTAB includes a high assay value, ensuring that users receive a product that is predominantly the desired compound, minimizing interference from impurities. The appearance as a white powder is standard, though variations in particle size might exist depending on the manufacturing process. Storage recommendations usually involve keeping it in a dark, dry place at room temperature to maintain its stability and purity over time. For those looking to buy DTAB, verifying these specifications from a reputable supplier is a key step.

When considering purchasing DTAB, factors such as purity, packaging options (commonly 25 kgs/drum), and availability of technical documents like Certificate of Analysis (COA) and Technical Data Sheet (TDS) are important. NINGBO INNO PHARMCHEM CO.,LTD. is a reliable manufacturer and supplier that provides high-purity DTAB, catering to the needs of various sectors. By choosing to buy DTAB from such a source, you ensure the quality and reliability necessary for successful outcomes in your applications, whether they are in complex biochemical research or large-scale industrial production.
