Description

CAS: 541-59-3 | C8H4AgKN2O4 | 339.10 g/mol

Reacts quantitatively with sulfhydryl groups.Maleimide is used to immobilize the bovine serum albumin-boronic acid conjugates in association with silica beads. Its nanoparticle surface favors the conjugation with cell penetration peptides. It is involved in Rhodium-catalyzed conjugate arylation with arylboronic acids. It is actively involved in Michael additions and Diels-Alder reactions by the addition across the double bond. It acts as crosslinking reagents in polymer chemistry.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
