CAS 2781-02-4
:Tetra(ethylene glycol) dithiol
Description:
Tetra(ethylene glycol) dithiol, with the CAS number 2781-02-4, is a chemical compound characterized by its two thiol (-SH) functional groups and a backbone consisting of four ethylene glycol units. This structure imparts both hydrophilic and thiol-reactive properties, making it useful in various applications, particularly in polymer chemistry and bioconjugation. The presence of thiol groups allows for the formation of disulfide bonds, which can be utilized in cross-linking reactions, enhancing the mechanical properties of materials. Additionally, the ethylene glycol segments contribute to the compound's solubility in water and compatibility with biological systems. Tetra(ethylene glycol) dithiol is often employed in the synthesis of hydrogels, drug delivery systems, and as a coupling agent in the modification of surfaces. Its low toxicity and biocompatibility further enhance its appeal in biomedical applications. Overall, this compound serves as a versatile building block in both organic synthesis and materials science.
