Cas no 1334177-84-2 (Hydroxy-PEG8-t-butyl ester)

Hydroxy-PEG8-t-butyl ester is a polyethylene glycol (PEG)-based linker featuring a terminal hydroxyl group and a t-butyl ester moiety. This compound is widely utilized in bioconjugation and pharmaceutical research due to its hydrophilic PEG spacer, which enhances solubility and reduces immunogenicity. The t-butyl ester group provides a stable protecting group for carboxylic acids, enabling controlled deprotection under mild acidic conditions. The hydroxyl terminus allows for further functionalization, making it a versatile intermediate in peptide synthesis, drug delivery systems, and polymer chemistry. Its well-defined molecular weight and high purity ensure reproducibility in applications requiring precise spacer lengths and controlled reactivity.
