Displaying 1 results of Methylated Dimer Impurities Methylated dimer impurities refer to the presence of molecules that have been formed by the dimerization of a drug molecule, with the addition of one or more methyl groups. These impurities can have a negative impact on the quality, safety, and efficacy of the drug product. Therefore, it is important to monitor and control their levels during the drug development process. Strategies for minimizing methylated dimer impurities involve optimizing reaction conditions, employing appropriate purification techniques, and implementing analytical methods for their quantification.
