New Products for Chemical Synthesis

Photo-Controlled Amino Acids
Photo-activated amino acids are versatile building blocks for incorporation into peptides, proteins, or small-molecule tools for photoaffinity labeling. Upon irradiation with UV light, a covalent bond is formed with nearby proteins, useful for probing cellular mechanisms, elucidating protein-protein interactions, or developing assays for target ID/validation. Fmoc-protected and unprotected versions are available.

New Catalysts from Umicore
We have added new palladium, platinum, and rhodium homogeneous catalysts form Umicore. This collection covers a variety of reactions: Suzuki-Miyaura Cross Coupling, Buchwald-Hartwig Amination, Mizoroki-Heck Coupling, hydrogenation, carbonylation, oxidation, hydrosilylation, and metathesis. Here we feature two of these catalysts, Umicore Hoveyda-Grubbs Catalyst M71 SIPr and Umicore Grubbs Catalyst M1b (C801), which are useful for alkene metathesis, cross metathesis, ring-closing metathesis, and self-metathesis.
