For procurement managers and R&D scientists in the chemical and pharmaceutical industries, identifying reliable suppliers of high-quality raw materials is a strategic imperative. N-Ethylmaleimide (CAS 128-53-0) is a specialty organic chemical that plays a crucial role as a versatile intermediate in various synthesis pathways, including peptide synthesis, protein modification, and the development of advanced materials. As a dedicated N-Ethylmaleimide manufacturer and supplier based in China, we understand the critical importance of purity, consistency, and dependable supply. This guide aims to assist you in making an informed decision when looking to buy N-Ethylmaleimide.

The chemical profile of N-Ethylmaleimide makes it a highly reactive and useful compound. Its maleimide ring system is susceptible to nucleophilic addition, particularly by thiol groups. This reactivity is exploited in:

  • Bioconjugation Chemistry: Facilitating the covalent linkage of proteins, antibodies, or peptides to other molecules, such as drugs, dyes, or polymers. The selectivity for cysteine residues is key to site-specific conjugation.
  • Organic Synthesis: Serving as a building block in the creation of complex organic molecules with diverse applications, including pharmaceuticals and agrochemicals.
  • Materials Science: Used in the development of specialty polymers and functional materials that require specific chemical properties.

When procuring N-Ethylmaleimide, several quality parameters must be considered:

  • Purity: The standard purity for N-Ethylmaleimide is often 98% by HPLC. Higher purity levels can lead to fewer side reactions, better yields, and more predictable outcomes in sensitive applications like peptide synthesis or biopharmaceutical development. Ensure your supplier provides detailed Certificates of Analysis (CoA) with each batch.
  • Physical Appearance: N-Ethylmaleimide is typically supplied as an off-white to white solid powder. Variations in appearance could indicate impurities or degradation.
  • CAS Number: Verifying the correct CAS number (128-53-0) is fundamental for ensuring you are obtaining the precise chemical required for your processes.
