For businesses in industries ranging from petrochemicals to pharmaceuticals, securing a consistent and high-quality supply of 2-Aminoethanol (MEA) is crucial. As a versatile chemical intermediate, MEA's unique bifunctional nature, possessing both an amine and an alcohol group, makes it indispensable in numerous applications. This guide is designed for procurement managers and R&D scientists seeking to understand the market and sourcing strategies for this vital compound from leading China manufacturers.

Understanding 2-Aminoethanol (CAS 141-43-5)

2-Aminoethanol, commonly known as Monoethanolamine (MEA), is a colorless, viscous liquid with a mild ammonia-like odor. Its chemical formula is C2H7NO, and it is highly soluble in water. Its dual functionality allows it to participate in a wide array of chemical reactions, making it a cornerstone in many industrial processes. Sourcing MEA from a reputable manufacturer ensures you receive a product with consistent purity, typically above 97%, which is essential for demanding applications.

Key Industrial Applications of MEA

The versatility of 2-Aminoethanol is evident in its broad application spectrum:

  • Gas Stream Scrubbing: MEA is widely used in the oil and gas industry to remove acidic gases like carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas and refinery streams. This process, often referred to as gas sweetening, is critical for meeting product specifications and environmental regulations. When looking to buy MEA for these applications, inquire about its suitability for amine treating units.
  • Chemical Intermediates: MEA serves as a fundamental building block in the synthesis of a vast range of chemicals. It's a precursor for ethyleneamines, surfactants, emulsifiers, chelating agents, and various personal care product ingredients. For R&D scientists formulating new products, understanding the reactivity of MEA is key.
  • Pharmaceuticals and Cosmetics: In the pharmaceutical sector, MEA acts as a buffering agent and is used in the preparation of emulsions. It's also a component in certain drug formulations, such as sclerosing agents. In cosmetics, it functions as a pH adjuster and emulsifier. Sourcing pharmaceutical-grade MEA requires strict adherence to quality standards.
  • Detergents and Cleaners: MEA is incorporated into heavy-duty detergents and cleaning formulations to improve their performance, often acting as a neutralizing agent and enhancing emulsification properties.
  • Other Uses: Additional applications include leather softening, corrosion inhibition, and as a raw material in the production of textiles and agricultural chemicals.

Sourcing Strategies and Supplier Selection in China

When seeking to purchase 2-Aminoethanol, partnering with a reputable China manufacturer is often the most cost-effective strategy. Look for suppliers who:

  • Maintain High Purity Standards: Verify that the manufacturer can consistently supply MEA with the required purity levels (e.g., 97% min) and provides detailed Certificates of Analysis (CoA).
  • Offer Competitive Pricing: Obtain quotes for bulk quantities to understand the market price and negotiate favorable terms. Key pricing factors include volume, packaging, and shipping terms.
  • Demonstrate Reliable Supply and Logistics: A strong supplier will have robust production capacity and efficient logistics to ensure timely delivery, whether you require drum quantities or bulk shipments.
  • Provide Technical Support: Experienced manufacturers can offer guidance on handling, safety, and specific application nuances of 2-Aminoethanol.

By understanding the multifaceted applications and carefully selecting your supplier, you can ensure a stable and high-quality supply of 2-Aminoethanol, empowering your business operations and product development. For those looking to buy 2-Aminoethanol, engaging with established manufacturers in China provides access to both quality and competitive pricing.
