mPEG-SS (Methoxypolyglycol succinimide succinate (ester bond)), CAS number 78274-32-5, is a polymer derivative with a special structure and function that is widely used in biomedicine, drug delivery, and materials science.
1. Physical properties
Properties: mPEG-SS is usually a solid or powder, depending on the molecular weight.
Solubility: Has good water solubility and organic solvent solubility.
Storage conditions: It is recommended to avoid light and dry storage at -20℃ to maintain its stability and activity.
2. Application field
Biocoupling: mPEG-SS can be used to modify biomolecules such as proteins, antibodies, peptides, etc. by reacting with amino groups to fix biomolecules to the surface of nanoparticles or biosensors.
Drug delivery: The reductive responsiveness of the disulfide bond enables it to release drugs in a specific cell or tumor environment, improving drug targeting and therapeutic effectiveness.
Biosensors: Can be used to build biosensors with stable chemical connections to sensor elements through their active groups.
Materials science: Can be used to prepare functional polymer materials, such as smart materials and nanomaterials.
Product technical advantage
SINOPEG offers high quality PEG derivatives with novel and diverse product structures, abundant substituting groups, and high end-group substitution rates.
High PEG functional group content - Content up to 99%
Functionalization of PEG is the most difficult of PEG products. The common problem of the main products on the market is that the functional group content is not high. And we master the modification technology, initiation system, unconventional precipitation method and system extraction method and other technologies and processes can easily produce high functional group content products. The functional group content of most products can reach 99%, which is much higher than the 90% or so of rivals.
High quality PEG molecular weight control -PDI <1.05
The single molecule chain of a polymer is usually composed of many small repeating units connected by polymerization. The design and control of the synthesis method has a crucial influence on the length of a single polymer segment and the similarity of the length of multiple polymer segments. Our PEG synthesis technology guarantees very good dispersion (PDI<1.05), while many other companies' products typically have PDI around 1.1.
