m-PEG3-Ms
This product is a monofunctional PEG linker with a methoxy end group, a PEG3 spacer, and a mesyl group. The mesyl group is an excellent leaving group, specifically enabling nucleophilic substitution for custom PEG derivatives in synthesis and bioconjugation.
Key Features and Benefits
-
Mesyl Group: Highly reactive leaving group for substitution with thiols, amines, or alkoxides.
-
PEG3 Spacer: Provides solubility and compact molecular spacing.
-
Methoxy End-Cap: Ensures stability and minimizes nonspecific interactions.
-
Reactive Intermediate: Serves as a precursor for functionalized PEG-based linkers.
-
High Purity: Guarantees reproducible performance in sensitive workflows.
Applications
-
Organic Synthesis: Generates functional PEG derivatives via mesyl substitution.
-
Bioconjugation: Builds PEGylated linkers for proteins, peptides, or probes.
-
Drug Delivery: Prepares PEG scaffolds for improved solubility and circulation.
-
Material Science: Introduces PEG functionality into polymers and nanostructures.
Storage and Handling
-
Storage: Keep at –20 °C in a sealed, light- and moisture-protected container.
-
Handling: Use anhydrous solvents such as DMF or DMSO to maintain reactivity.
This product integrates a mesyl leaving group with a PEG3 chain, specifically providing a compact and reactive intermediate for linker synthesis, drug delivery, and bioconjugation.
