In the dynamic field of chemical sciences, efficiency, accuracy, and reliability are cornerstones of progress. Tetramethylammonium sulfate (CAS 14190-16-0) is a compound that embodies these principles, serving a dual purpose as both a powerful phase transfer catalyst in organic synthesis and a critical reagent in High-Performance Liquid Chromatography (HPLC). For R&D scientists, formulators, and procurement managers, understanding the value of this chemical and how to source it effectively from China is key to operational success.

Tetramethylammonium sulfate is a water-soluble, white crystalline powder with the CAS number 14190-16-0. Its chemical structure, a tetramethylammonium cation paired with a sulfate anion, confers unique properties that make it highly useful in diverse chemical applications. As a phase transfer catalyst (PTC), it facilitates reactions by transferring reactive anions from an aqueous phase into an organic phase, or vice versa. This is particularly advantageous in reactions involving polar and non-polar reactants that are not mutually soluble. By bridging this solubility gap, Tetramethylammonium sulfate dramatically speeds up reaction rates, improves yields, and often allows for the use of milder conditions, leading to more sustainable and cost-effective synthesis processes.

The practical applications of Tetramethylammonium sulfate in organic synthesis are broad and impactful. It is instrumental in reactions such as halogen replacement, where it promotes the substitution of halide ions. It also plays a significant role in oxidation and reduction (REDOX) reactions, essential for modifying molecular structures. Furthermore, its utility in N-alkylation, a fundamental process for introducing alkyl groups to nitrogen atoms, is widely recognized. The generation of dichlorocarbene, a key intermediate for cyclopropanation and other valuable carbon-carbon bond-forming reactions, is another critical application where this catalyst proves indispensable. When researchers seek to buy chemical intermediates that enable these complex transformations, Tetramethylammonium sulfate, with its guaranteed purity of 98% or more, is a top choice.

Complementing its role in synthesis, Tetramethylammonium sulfate also serves as a high-performance liquid chromatography (HPLC) analysis reagent. In HPLC, it can function as an ion-pairing agent, enhancing the retention and separation of ionic or polar compounds on the chromatographic column. This improves the resolution and accuracy of analytical results, making it a vital tool for quality control and research laboratories. The consistent purity offered by manufacturers is crucial for ensuring reliable analytical performance. Therefore, when you need to buy Tetramethylammonium sulfate for analytical purposes, prioritizing suppliers with stringent quality assurance is paramount.

For organizations looking to procure Tetramethylammonium sulfate, the Chinese chemical market offers a compelling sourcing option. China boasts a mature chemical manufacturing sector capable of producing high-purity compounds at competitive price points. Reputable manufacturers and suppliers provide Tetramethylammonium sulfate that meets international quality standards, often accompanied by comprehensive documentation like Certificates of Analysis. Procurement professionals should actively seek out these suppliers, focusing on their production capacity, quality control measures, and logistical capabilities. Inquiring about bulk purchase options, with minimum order quantities typically around 25kg, and requesting a price quote are essential steps in securing a cost-effective and reliable supply chain.

In conclusion, Tetramethylammonium sulfate (CAS 14190-16-0) is a multifaceted chemical that significantly benefits both organic synthesis and analytical chemistry. Its effectiveness as a phase transfer catalyst and its utility as an HPLC reagent highlight its importance. By partnering with trusted Tetramethylammonium sulfate manufacturers and suppliers in China, businesses can access a high-purity, cost-effective solution for their diverse chemical needs. Reaching out for a quote is the initial step to integrating this valuable compound into your operations.
