Product Information

• Name: 4-Methanesulfonyloxybutanol
• Synonyms: Busulfan impurity 4
• Brand: Biosynth
• Description: 4-Methanesulfonyloxybutanol is a chemical substance with the molecular formula CH3SO2CH(CH2OH)CH2OH. It is used as an intermediate in the synthesis of 4-methanesulfonyloxybutanol, which is a potent inhibitor of busulfan-induced leukopenia and myelosuppression. This substance has been shown to be highly effective in preventing busulfan-induced side effects when administered intravenously. 4-Methanesulfonyloxybutanol is chemically synthesized by intramolecular alkylation of butanol, followed by hydrolysis. The reaction product can be detected using an ionization detector in conjunction with gas chromatography. This product is an alkylation agent that reacts with polypropylene to produce polypropylene glycols.
