In the diverse landscape of chemical compounds, certain molecules stand out due to their unique structure and broad applicability. Polyethylene Glycol Diamine (PEG diamine), identified by the CAS number 24991-53-5, is one such compound. This versatile chemical, often referred to by its structural formula H2N-PEG-NH2, is a derivative of polyethylene glycol that features amine functional groups at both ends of its polymer chain. Its importance spans multiple fields, from advanced material science to pharmaceutical development, making it a key reagent for researchers and manufacturers worldwide. As a leading supplier from China, we provide access to this critical intermediate.

At its core, PEG diamine is a homobifunctional linker. This means it has identical reactive groups at both ends, enabling it to connect two different molecules or functionalize a surface symmetrically. The PEG backbone itself is a hydrophilic, flexible, and biocompatible polymer, which imparts desirable properties to the resulting conjugates. These properties include enhanced water solubility, increased hydrodynamic size, and a reduced tendency to elicit an immune response, a phenomenon known as pegylation. This makes PEG diamine an indispensable tool for researchers aiming to improve the performance of biomolecules or create novel materials.

The applications of PEG diamine are vast. In bioconjugation, it's used to create antibody-drug conjugates (ADCs), where the PEG linker connects a cytotoxic drug to an antibody targeting specific cells. It's also employed in the synthesis of PEGylated proteins, enhancing their therapeutic half-life and efficacy. In material science, PEG diamine can be used as a crosslinker for hydrogels, creating soft, water-swollen networks suitable for tissue engineering scaffolds or drug delivery matrices. The ability to easily buy this compound from reliable suppliers in China simplifies the procurement process for research institutions and industrial partners.

Understanding the significance of PEG diamine (CAS 24991-53-5) is crucial for any scientist or engineer working with advanced chemical or biological systems.
