Dodecyltrimethylammonium Bromide (CAS 1119-94-4), commonly known as DTAB, is a positively charged quaternary ammonium salt that functions as a cationic surfactant. This characteristic makes it a highly versatile compound with critical applications in various scientific and industrial fields. For professionals in chemical procurement and research and development, understanding DTAB's properties and its market positioning is key to making informed purchasing decisions. Sourcing this essential chemical from reliable partners is paramount for achieving optimal results.

The molecular structure of DTAB, featuring a twelve-carbon alkyl chain and a trimethylammonium group, dictates its amphipathic behavior. This allows it to effectively interact with surfaces and to form micelles in aqueous solutions, a property that underpins many of its uses. Typically presented as a white to slightly yellow powder, DTAB boasts a high melting point of around 246°C, signifying its stability for various handling and storage conditions. Critically, its high purity, often exceeding 99%, ensures its efficacy in demanding applications such as precise analytical procedures and complex chemical syntheses.

A significant application of Dodecyltrimethylammonium Bromide is in the manufacturing of diagnostic reagents. It is a key ingredient in lysing buffers used in hematology laboratories. These buffers are essential for breaking open red blood cells to measure hemoglobin levels and other cellular components. The accuracy of diagnostic tests relies heavily on the purity and consistency of the reagents used. Therefore, diagnostic kit manufacturers prioritize sourcing DTAB from reputable manufacturers who can guarantee stringent quality control and batch-to-batch consistency. For such buyers, finding a trusted supplier is non-negotiable.

In the realm of organic synthesis, DTAB is widely recognized for its role as a phase transfer catalyst (PTC). This catalytic function is invaluable for accelerating reactions that involve reactants residing in different, immiscible phases, such as aqueous and organic systems. By facilitating the transfer of reactants across phase boundaries, DTAB significantly improves reaction rates, yields, and often the selectivity of the desired product. This makes it a go-to compound for synthesizing complex organic molecules, including pharmaceuticals and fine chemicals. If you are looking to buy this essential catalyst, exploring the offerings from established Chinese manufacturers can provide excellent value, balancing quality with competitive pricing.

Beyond these primary applications, DTAB also finds utility in research for studying interfacial phenomena, in the synthesis of nanoparticles as a stabilizing agent, and in various formulation processes. Its consistent performance and unique chemical properties make it a staple in many laboratories and industrial processes.

For companies in need of Dodecyltrimethylammonium Bromide, identifying a reliable supplier is crucial. China offers a vast chemical manufacturing base, with numerous companies providing DTAB at attractive prices. When selecting a supplier, it is vital to look beyond just the cost. Factors such as product purity, adherence to international quality standards, availability of Certificates of Analysis (CoA), and the supplier's logistical capabilities are equally important. Engaging with suppliers who offer transparent communication and dependable support can streamline the procurement process.

In essence, Dodecyltrimethylammonium Bromide (CAS 1119-94-4) is a cornerstone chemical for industries requiring high-performance surfactants and catalysts. Its application in diagnostics and synthesis underscores its critical importance. By partnering with qualified manufacturers and suppliers, particularly those in China who can offer competitive pricing and assured quality, businesses can secure a vital component for their product development and manufacturing pipelines.
