HO-PEG20-t-butyl ester
This product is a heterobifunctional PEG reagent featuring a terminal hydroxyl group and a t-butyl ester as an acid-labile protecting group. The long PEG20 chain provides excellent solubility, flexibility, and spacing, making it especially valuable for orthogonal conjugation, bioconjugation, and drug delivery.
Key Features and Benefits:
-
Hydroxyl Group: Serves as a versatile handle for further derivatization.
-
t-Butyl Ester: Acid-labile protection enables controlled deprotection.
-
PEG20 Spacer: Provides high solubility, hydrophilicity, and extended spacing.
-
Orthogonal Reactivity: Supports stepwise, multifunctional synthesis.
-
High Purity: Ensures reliable results in sensitive applications.
Applications:
-
Bioconjugation: Introduces hydroxyl and protected ester handles to biomolecules.
-
Drug Delivery: Provides long PEG scaffolds for improved pharmacokinetics.
-
Probe Development: Builds multifunctional imaging and diagnostic tools.
-
Synthetic Chemistry: Useful intermediate for orthogonal synthetic schemes.
Storage and Handling:
-
Storage: Store at –20 °C in a tightly sealed, moisture- and light-protected container.
-
Handling: Use anhydrous solvents (e.g., DMF, DMSO); deprotect t-butyl ester under acidic conditions.
This product combines hydroxyl functionality with a protected ester in a PEG20 scaffold, specifically offering high solubility and flexibility for advanced conjugation.
