AI Overview
-PEG-CO-
tBu (
-Amino-
-tert butyl propionate poly(ethylene glycol)) is a linear, heterobifunctional PEG linker featuring a reactive amine and a protected carboxylic acid (t-butyl ester). It is used in bioconjugation for attaching PEG chains, with the protected carboxylic acid deprotected under acidic or basic conditions.
Key Aspects of
-PEG-CO-$O$tBu:
- Structure: Linear PEG with an amine () at one terminus and a tert-butyl ester protected carboxyl () at the other.
- Applications: Commonly used as a crosslinking reagent, in PEGylation, and as a reagent for peptide synthesis.
- Molecular Weight: Available in various molecular weights, including 2K, 5K, 10K, 20K, and 40K Da.
- Chemical Properties: Typically supplied as HCl or TFA salts to maintain stability of the amine group.
- Solubility: Polyethylene glycols are generally soluble in water, methanol, ethanol, and dichloromethane.
