Methoxytrityl-S

Methoxytrityl-S (Mmt-S) Uniform PEG Thiolation Reagents are PEG-based molecules that incorporate a thiol (-SH) group protected with a methoxytrityl (Mmt) group.

The Mmt protecting group allows for controlled, selective deprotection under mild acidic conditions, enabling stepwise thiol conjugation strategies. These reagents are ideal for applications in drug delivery, surface modification, and bioconjugation, where thiol groups must be unmasked at a specific stage without affecting other sensitive functional groups.
