Mal-PEG4-Lys(TFA)-NH-m-PEG24 CAS:2384191-64-2 is a type of small molecule drug that is composed of several functional groups. The Mal group, also known as maleimide, is a reactive functional group that can be used to conjugate the drug to other molecules, such as proteins or antibodies. The PEG4 group is a type of polyethylene glycol spacer that is used to improve the solubility and stability of the drug in solution. The Lys(TFA) group is a lysine residue that has been protected with a trifluoroacetic acid group, which can be removed under specific conditions to expose the free amino group. The NH group is a free amino group that can be used for further conjugation with other molecules. Finally, the m-PEG24 group is another polyethylene glycol spacer that is used to improve the solubility and stability of the drug in solution.
