N,N'-Methylenebisacrylamide

Updated: 2026-08-05

Overview

N,N'-Methylenebisacrylamide (MBAA) is a widely used crosslinking agent in polymer chemistry, particularly known for its role in polyacrylamide gel electrophoresis. It functions by forming bridges between polymer chains, thereby enhancing the mechanical strength and stability of the resulting gel. MBAA is a derivative of acrylamide and is valued for its ability to create well-defined polymer networks. The compound is commonly employed in laboratories and industrial settings due to its reliability and effectiveness. Its applications extend beyond electrophoresis to include water treatment, adhesives, and coatings, where crosslinking is required to improve material performance.

Physical and Chemical Properties

MBAA is a white crystalline powder with a molecular weight of 154.17 g/mol. It is soluble in water, ethanol, and acetone, making it versatile for various solvent-based applications. The compound decomposes at temperatures between 185-190°C, which is a critical consideration during processing and storage. One of the key properties of MBAA is its ability to form covalent bonds with other polymer chains, creating a three-dimensional network. This property is essential for applications requiring high gel strength and thermal stability. The solubility and reactivity of MBAA make it a preferred choice for researchers and engineers working with polymer matrices.

Main Applications

MBAA is primarily used in polyacrylamide gel electrophoresis (PAGE), where it serves as a crosslinker to stabilize the gel matrix. This application is crucial in molecular biology for separating proteins and nucleic acids based on size. The compound's ability to form uniform gels ensures accurate and reproducible results in laboratory experiments. In addition to electrophoresis, MBAA is utilized in water treatment processes to create flocculants that remove impurities. It is also found in adhesives and coatings, where crosslinking improves durability and resistance to environmental factors. The versatility of MBAA makes it a valuable component in both scientific and industrial applications.

Safety and Storage

MBAA is classified as harmful if inhaled or ingested, necessitating the use of personal protective equipment (PPE) such as gloves, goggles, and masks. Proper ventilation is essential when handling the compound to minimize exposure to airborne particles. Skin contact should be avoided, as it may cause irritation or allergic reactions. Storage conditions for MBAA include keeping the compound in a cool, dry place away from direct light and moisture. Containers should be tightly sealed to prevent contamination and degradation. It is advisable to store MBAA separately from incompatible substances, such as strong oxidizers, to avoid hazardous reactions.

B2B Procurement Guide

When procuring MBAA, it is important to verify the purity and quality of the product. Suppliers should provide a Certificate of Analysis (COA) detailing the compound's specifications, including purity levels and potential contaminants. Bulk purchases may offer cost advantages, but buyers should ensure proper storage facilities are available to maintain product integrity. Price ranges for MBAA typically vary between $50 and $100 per kilogram, depending on purity and order quantity. It is advisable to compare offerings from multiple suppliers to secure competitive pricing. Additionally, buyers should consider the supplier's reputation, delivery timelines, and compliance with regulatory standards to ensure a smooth procurement process.
