Tentagel S SH

Tentagel S SH is a specialized polymer-based material often utilized in the field of chemistry, particularly for applications involving solid-phase peptide synthesis (SPPS). Its name derives from its structure: a ′tentacle′ polymer gel that contains a thiol group (SH). The SH in the name specifically indicates the presence of a sulfur atom bonded to a hydrogen atom, which is a functional group known for its reactivity. This resin is a type of cross-linked polystyrene and polyethylene glycol (PEG) copolymer. The polystyrene forms the solid ′backbone′ of the resin, while the PEG chains, or ′tentacles′, extend from this backbone. These PEG chains are responsible for the high solvation properties of Tentagel resins, which allow reactions to occur at nearly the same rate as in solution phase. The sulfur-containing thiol group in Tentagel S SH is particularly useful because it can form strong covalent bonds with other molecules, making it an excellent choice for linking to a wide variety of compounds. The resin beads are usually swollen in solvents like dichloromethane or dimethylformamide for use in chemical reactions.
