I. [Product Description]
ALD-PEG-SG (Propionaldehyde-Polyethylene Glycol-Succinimidyl Glutarate) is a highly efficient and multi-functional organic intermediate, which combines biocompatibility with controllable reaction activity. It is widely used in the synthesis of pharmaceutical intermediates and the modification of polymer materials. The active aldehyde group and succinimidyl ester group in its molecule can achieve directional coupling and covalent cross-linking respectively. By matching with PEG segments of different molecular weights, the water solubility and steric hindrance effect of the product can be precisely regulated.

II. [Product Details]
    【Appearance】Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid.
    【Stability】Store under refrigeration and avoid repeated freeze-thaw cycles.
    【Solvents】Common organic solvents such as chloroform, dichloromethane, and DMSO.
    【Molecular Weight】(PEG): 2000, 3400, 5000. Other molecular weights can be customized.
    【Storage Conditions】Store in a sealed, dry place at a low temperature below 4°C.
▪ Precautions: ▶ To ensure product stability, please open the package for use only after constant temperature drying!

III. [Application Fields]
    1. Bioconjugation: Through the Schiff base reaction between the aldehyde group and the amino group, achieve the site-specific labeling of biological macromolecules such as proteins and polypeptides.
    2. Surface Modification of Nanomaterials: Use the PEG segment to improve the dispersion and anti-non-specific adsorption properties of nanoparticles.
    3. Cross-linking of Polymer Materials: React the succinimidyl ester group with hydroxyl/amino groups to construct a three-dimensional network structure.
    4. Construction of Functional Carriers: Design pH-responsive linking arms for drug delivery systems.
    5. Development of In Vitro Diagnostic Reagents: Serve as a bridging intermediate between signal molecules and solid-phase matrices.
