Exceptional Solubility and Versatilityn-Dodecyltrimethylammonium bromide dissolves readily in water and alcohol, making it especially valuable for diverse applications in laboratories and industry. Its cationic surfactant properties enhance phase transfer processes, allowing for efficient chemical synthesis, emulsification, and reaction mediation. Its compatibility with custom packaging ensures suitability for different usage needs and operational scales.
Safe Handling and StorageDTAB is supplied as a stable, white crystalline powder, with a shelf life of up to 24 months when stored in a tightly closed container in a cool, dry, and well-ventilated area. Although not classified as regulated for transport, it is important to use personal protective equipment when handling, due to its irritant qualities affecting the skin and eyes. Proper storage maintains product purity and prolongs usability.
Extensive ApplicationsDTAB serves as a key phase transfer catalyst, surfactant, emulsifier, antibacterial agent, and reagent. Its high purity and performance make it an essential component in research, chemical manufacturing, and pharmaceutical preparations. Its ability to facilitate reactions and control interfacial properties makes it particularly beneficial in complex syntheses and formulations.
FAQ's of n-Dodecyltrimethylammonium bromide:
Q: How should n-Dodecyltrimethylammonium bromide (DTAB) be stored for optimal shelf life?
A: DTAB should be stored in a tightly closed container, placed in a cool, dry, and well-ventilated environment. Proper storage helps preserve its purity (99%) and ensures a shelf life of up to 24 months.
Q: What are the main applications of DTAB in laboratory and industrial settings?
A: DTAB is commonly used as a phase transfer catalyst, cationic surfactant, emulsifier, antibacterial agent, and reagent. Its versatility supports chemical synthesis, pharmaceuticals, and research applications.
Q: When should personal protective equipment be used with DTAB?
A: Protective equipment such as gloves and safety goggles should be used whenever handling DTAB, as it is an irritant to skin and eyes. Careful handling minimizes exposure risks.
Q: Where is DTAB typically employed in chemical processes?
A: DTAB is particularly useful in processes that require phase transfer catalysis or stable emulsification. It is widely used in chemical synthesis, laboratories, and manufacturing processes involving interfacial reactions.
Q: What is the process for dissolving DTAB for use as a surfactant?
A: DTAB can be dissolved in water or alcohol at room temperature, as it has excellent solubility in these solvents. For typical applications, a 1% solution is prepared, which results in a pH between 6 and 8.
Q: How does DTAB benefit chemical synthesis operations?
A: DTAB's cationic surfactant nature enhances phase transfer and interfacial reactions, facilitating efficient product formation. Its high purity and stable physical state provide reliable performance in controlled synthesis environments.
