반응시간 단축을 위한 표면적 증가 2ml PFA 튜브 사용 Our specially designed flow reactor (meant to be used with our PhotoRedOx Box™) enables scaling of photochemistry reactions by significantly increasing surface area. This flow reactor uses PFA tubing and has volume of 2 ml. PhotoRedOx Flow Reactor™ Description The common limitation to scaling up photoredox chemistry is due to the low penetration of the light in t..

Our BMO kits enable, in three simple steps, synthesis of metabolites directly from the parent drug. HepatoChem has developed a revolutionary way to screen, optimize, and produce metabolites directly from drug candidates. The BMO Kit exploits an optimized panel of catalytic chemical reaction conditions using organometallic catalysts in a multi-well parallel format. This tool mimics the suite of c..

2 sets of Ullmann reaction conditions with CuI, 5 different ligands and 3 bases (K2CO3, K3PO4, and Cs2CO3). 36 reaction vials total. The typical protocol is performed at 0.1 mol/l concentration reaction condition and 1 to 1 ratio substrates in 500 µl selected solvent. Resulting catalyst loading is 10%. 1.1 equivalents of base are preloaded (55 µmol). It is possible to decrease substrate concentr..

Photoredox chemistry has been reported in the literature using a wide range of catalysts and reagents. However, often these reactions are highly substrate, solvent and base specific. In order to facilitate the screening of common photochemistry reactions, HepatoChem has released a series of high-throughput photocatalysis reaction screening kits combining common Iridium, Nickel, ligand and base c..

The Pd Catalyzed Amination Kits are ideal tools for the investigation of cross-coupling reaction conditions. This enables to conveniently screen multiple reaction conditions simultaneously using pre-weighed catalysts and reagents. The kit contains all reagents and supplies to perform the reaction conditions. We offer pre-selected arrays of precatalysts and salts or custom arrays depending on you..
