Dodecyltrimethylammonium Bromide (CAS 1119-94-4), often abbreviated as DTAB, is a highly functional cationic surfactant that plays a crucial role in various industrial applications. From its utility in sophisticated diagnostic assays to its effectiveness as a catalyst in chemical synthesis, DTAB is a compound valued for its versatility and performance. For industry professionals seeking to source this chemical, understanding its properties and the market landscape is key.

As a cationic surfactant, DTAB is characterized by its amphipathic nature, possessing both a long hydrocarbon chain (dodecyl) and a positively charged quaternary ammonium head group. This structure allows it to interact with various interfaces and to form organized structures like micelles in aqueous solutions. Typically appearing as a white to slightly yellow powder, DTAB has a melting point of approximately 246°C, indicating good stability for handling and storage. Its purity, often specified at 99% or higher, is a critical parameter for its effectiveness in sensitive applications.

One of the primary industrial applications of Dodecyltrimethylammonium Bromide is in the field of diagnostic reagents. It is an integral component in many lysing solutions used for hematological analyses. These solutions are designed to efficiently lyse red blood cells, enabling the accurate measurement of hemoglobin and other intracellular components. The reliability of diagnostic results hinges on the quality of the reagents, making DTAB a vital raw material for manufacturers of medical diagnostic kits. Procuring high-purity DTAB from a dependable manufacturer is therefore essential for this sector.

In the realm of chemical synthesis, DTAB functions as an effective phase transfer catalyst (PTC). This capability is highly sought after in industries that require efficient chemical transformations. By facilitating the reaction between species in different phases, DTAB enhances reaction kinetics and yields, often under milder conditions than would otherwise be possible. This makes it a valuable tool for producing a wide range of organic compounds, from pharmaceuticals to specialty chemicals. If your company is looking to buy DTAB for catalytic applications, exploring options from established suppliers, especially those in China offering competitive pricing, can be advantageous.

Furthermore, DTAB finds use in material science and research as a stabilizing agent in the synthesis of nanoparticles, controlling their size and preventing aggregation. Its surfactant properties are also leveraged in various formulations and interfacial studies.

For industrial procurement, identifying a reliable supplier of Dodecyltrimethylammonium Bromide is crucial. Chinese chemical manufacturers have a significant presence in the global market, offering high-quality DTAB at competitive prices. When making a purchasing decision, it is important to consider factors such as the supplier's production capacity, quality control measures, and their ability to provide consistent product specifications and timely deliveries. Requesting samples and reviewing Certificates of Analysis (CoA) are standard practices to ensure the material meets your exact requirements.

In conclusion, Dodecyltrimethylammonium Bromide (CAS 1119-94-4) is a compound of significant industrial value, particularly in diagnostics and chemical synthesis. Its efficacy as a surfactant and phase transfer catalyst makes it indispensable. By partnering with reputable manufacturers and suppliers, who can offer both quality and competitive pricing, businesses can ensure a stable and efficient supply of this versatile chemical for their operations.
