Pentaethylene Glycol Monomethyl Ether (mPEG5-OH) is a fascinating organic intermediate that plays a significant role in various scientific and industrial applications. NINGBO INNO PHARMCHEM CO.,LTD. is pleased to provide insights into the detailed chemical properties and diverse uses of this compound, often sought after for its unique molecular structure and reactivity.

Chemically defined as C11H24O6, with a molecular weight of 252.3, mPEG5-OH is characterized by its five repeating ethylene oxide units capped with a methyl ether group at one end and a hydroxyl group at the other. This bifunctional nature makes it a valuable building block. The terminal hydroxyl group (OH) is particularly important as it allows for further chemical modifications and conjugations, making it a versatile reagent in complex synthesis pathways. The methyl ether end provides a non-reactive cap, ensuring that reactions primarily occur at the hydroxyl terminus.

The compound typically appears as a colorless to light yellow liquid, with a specified assay of ≥98.0%, indicating high purity essential for precision in research and manufacturing. Its physical properties, such as a density of approximately 1.08 and a boiling point around 110 °C, are critical parameters for handling and process design. The refractive index, ranging from 1.4480 to 1.4520, is another key characteristic used for quality control and identification.

The applications of mPEG5-OH are extensive and continue to expand. In the field of polymer chemistry, it is instrumental in creating grafting polymer compounds and developing new materials. The hydrophilic nature of the PEG chain can impart improved flexibility, water solubility, and biocompatibility to the resulting polymers. This makes mPEG5-OH a sought-after component for advanced materials research, including the development of hydrogels and modified surfaces.

Furthermore, mPEG5-OH serves as a critical support in peptide synthesis and ligand research. Its incorporation can enhance the solubility and stability of synthesized peptides, facilitating their purification and application in areas like drug delivery and diagnostics. The ability to buy mPEG5-OH of high quality from suppliers like NINGBO INNO PHARMCHEM CO.,LTD. ensures that these advanced research efforts can proceed without compromise.

In functional coatings, mPEG5-OH can be used to modify surfaces, imparting properties such as reduced friction, improved wettability, or anti-fouling characteristics. This versatility underscores its importance across multiple sectors, from biomedical engineering to industrial manufacturing.

For those in need of this specialized chemical, understanding its properties is key to unlocking its full potential. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing reliable access to Pentaethylene Glycol Monomethyl Ether, supporting innovation and progress in the scientific community.
