N,N'-Methylenebisacrylamide, commonly known as MBA or Bis-acrylamide, is a fundamental chemical compound that plays a pivotal role in the field of polymer science. As a highly effective cross-linking agent, it is indispensable for the creation of stable and robust polymer networks. Its ability to bridge polymer chains is particularly vital in applications such as the formation of polyacrylamide gels, a cornerstone of modern biochemical research and diagnostics.

The precise structure of MBA allows it to copolymerize with acrylamide monomers. This process results in the formation of a three-dimensional cross-linked network, which is significantly different from the linear chains that would form from acrylamide alone. This cross-linked structure is what gives polyacrylamide gels their unique properties, including mechanical strength and controlled pore sizes. For researchers and procurement managers in the life sciences sector, understanding the quality and consistency of the MBA they source is paramount. The CAS number for this essential chemical is 110-26-9.

In the context of gel electrophoresis, such as SDS-PAGE (Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis), the concentration of MBA directly influences the pore size of the gel. Higher concentrations of MBA lead to smaller pores, which are ideal for separating smaller proteins. Conversely, lower concentrations create larger pores, suitable for resolving larger protein molecules. Therefore, sourcing high-purity N,N'-Methylenebisacrylamide from a reputable manufacturer is critical for reproducible and accurate experimental results.

Beyond laboratory applications, MBA also finds significant use in various industrial sectors. Its cross-linking capabilities are harnessed in the production of water-based fracturing fluids for oilfield operations, where it enhances stability and plugging efficiency. In water treatment, it aids in the decolorization and purification of water with high organic loads. Furthermore, its role in construction as a component of chemical grouting materials for stable foundations and waterproofing underscores its versatility.

For businesses seeking to purchase N,N'-Methylenebisacrylamide, identifying a reliable China supplier is often a strategic move to secure competitive pricing and consistent quality. Manufacturers specializing in fine chemical intermediates understand the stringent requirements for purity and performance. When looking to buy MBA, whether for bulk industrial use or specialized research, engaging with an established supplier who can provide detailed specifications and reliable delivery is key. Consider your specific application needs and ensure your chosen manufacturer can meet them. The availability of MBA at a competitive factory price from China makes it an attractive option for many global industries.
