m-PEG9-Tos(m-PEG9-Tos) is a compound whose chemical formula is C22H38O7S. It is a white solid powder, soluble in some organic solvents, such as methanol, ethanol and dimethylformamide.
m-PEG9-Tos can be used as a functional modifier of polymer materials, which is commonly used in biomedical and drug delivery fields. It is a soluble polyethylene glycol derivative with good biocompatibility, which can improve the solubility and stability of the drug and prolong the blood half-life of the drug in the body.
The preparation method of m-PEG9-Tos is generally obtained by the reaction of ethylene glycol and p-Toluenesulfonyl chloride. Specifically, ethylene glycol and p-Toluenesulfonyl chloride are reacted under alkaline conditions, sufficiently stirred at an appropriate temperature, and finally the product is obtained by crystallization or filtration.
Pay attention to safety issues when using m-PEG9-Tos. It may be irritating to the eyes, skin and respiratory tract, so wear appropriate protective measures such as gloves, goggles and masks during operation. If external contact to the skin or eyes, should immediately rinse with plenty of water, and medical treatment.
