DSPE-PEG8-Mal is a DSPE–polyethylene glycol conjugate functionalised with a maleimide group, supplied at a minimum purity of 95 % for biochemical laboratory applications. Registered under CAS number 2112737-94-5, the compound has the empirical formula C₆₄H₁₁₉N₂O₁₉P and a molar mass of 1251,6 g/mol. The combination of a DSPE lipid moiety, a PEG8 spacer and a terminal maleimide provides a defined amphiphilic linker architecture for research use. It is CAS number, empirical formula and molar mass are stated to support precise weighing, solution preparation and experimental documentation. This biochemical is available from manufacturer Carl ROTH among specialty reagents intended for life-science and bioconjugation-related work. DSPE-PEG8-Mal thus offers clearly specified molecular identity in a format suited to focused laboratory studies.
