mPEG-NH₂ (aminomodified polyethylene glycol) is a polymer widely used in biomedical and materials science with an amino (-NH₂) functional group at the end of its molecular chain. The hydrophilicity and amino reactivity of polyethylene glycol make it excellent in a variety of applications.

Amino (-NH₂) functional group

Chemical properties:
An amino group is a strongly alkaline functional group capable of accepting protons (H +), giving it the ability to form an ammonia ion (NH + +) in water.
The presence of amino groups makes mPEG-NH₂ highly reactive and able to react with many chemicals, such as aldehydes, ketones, and acids.

Biocompatibility:
The amino functional group is friendly to the organism and can increase the interaction between mPEG-NH₂ and biomolecules and reduce the immune response.

Applications:
Drug delivery: Amino functional groups contribute to drug binding and release, enhancing drug bioavailability.
Modification of biomacromolecules: Amino groups can be used to modify proteins and nucleic acids to improve their stability and function.
Crosslinkers: When synthesizing polymers or materials, amino groups can be used as crosslinkers to enhance the mechanical properties and durability of the material.

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.
