In the realm of chemical synthesis, particularly for advanced applications in pharmaceuticals, biotechnology, and materials science, the selection of high-quality reagents is non-negotiable. Fmoc-NH-PEG4-Propionic Acid, identified by CAS number 557756-85-1, stands out as a key component for sophisticated bioconjugation and peptide synthesis projects. For procurement managers and research scientists, understanding the properties of this linker and its sourcing from reliable manufacturers, especially those based in China, is critical for project success.

Fmoc-NH-PEG4-Propionic Acid, also known as 1-(9H-Fluoren-9-yl)-3-oxo-2,7,10,13,16-pentaoxa-4-azanonadecan-19-oic acid, is a specialized linker. Its structure comprises a polyethylene glycol (PEG) chain of moderate length, functionalized with an Fmoc-protected amine at one end and a carboxylic acid at the other. The Fmoc group offers a convenient method for controlled deprotection under mild basic conditions, revealing a reactive primary amine for subsequent conjugation. The PEG chain contributes hydrophilicity, which is essential for improving the solubility and bioavailability of attached molecules, while the carboxylic acid provides a reactive site for forming amide bonds with amines.

When you decide to buy Fmoc-NH-PEG4-Propionic Acid, prioritizing quality is paramount. Reputable manufacturers, including those in China, typically offer this product with a purity of 95% or higher. This high purity minimizes undesired side reactions, ensuring the integrity of your synthesized peptides or bioconjugates. Procuring from a trusted CAS 557756-85-1 supplier in China often provides a competitive advantage, balancing cost-effectiveness with consistent quality and reliable supply chains.

The applications for this versatile linker are broad. In peptide synthesis, it is used to create modified peptides with enhanced solubility or to introduce specific functional groups. For bioconjugation, it serves as an ideal linker to attach drugs to antibodies (Antibody-Drug Conjugates or ADCs), label proteins, or immobilize molecules onto surfaces for biosensing. The flexibility offered by the two distinct reactive ends makes it adaptable to numerous conjugation strategies. When researching peptide synthesis PEG linker price, consider the value it brings in terms of improved experimental outcomes and reduced purification challenges.

For organizations requiring larger volumes, partnering with a manufacturer that can ensure scalability and consistent batch-to-batch quality is crucial. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to meeting these needs, offering both standard catalog products and custom synthesis services.
