Discontinued product5-Fluoro-2-nitrobenzoyl chloride
CAS:5-Fluoro-2-nitrobenzoyl chloride is a conformationally locked macrocyclic compound that has been synthesized by solid phase synthesis. It is found in two conformational states and can be made to switch between these two states by applying a force to the molecule. This conformation can be controlled by changing the side chain of 5-fluoro-2-nitrobenzoyl chloride, which can be done experimentally. The conformational behavior of this macrocycle was studied using molecular dynamics simulations and it was found that there are four possible conformations for the molecule. The conformations with different side chains were found to have different energies, which could be used as a measure of their relative stability.

Discontinued product4-chloropyridine-3-sulfonyl chloride
CAS:4-Chloropyridine-3-sulfonyl chloride is a thrombin inhibitor that has been discovered through the use of in vitro screening methods. It is a small molecule with lipophilic properties and oral bioavailability. This compound inhibits thrombin by binding to the active site of the enzyme, which prevents the formation of an enzyme-thrombin complex. The discovery was made using a pharmacophore-based approach and further modifications were made to improve its potency and increase its lipophilicity. This compound also exhibits an acceptable level of bioavailability in vivo, which may be due to its high solubility in water.Formula:C5H3Cl2NO2SPurity:Min. 95%Molecular weight:212.1 g/molRef: 3D-IBA26344

Discontinued product1-Bromo-1-methylcyclohexane
CAS:1-Bromo-1-methylcyclohexane is a monomolecular gas that is used as an intermediate in organic synthesis. It reacts with halides to form cyclopentyl derivatives. This reaction has been shown to be faster than the corresponding reaction of 1-bromocyclohexane with chlorides or bromides. The rate of this reaction may be due to the polarizability and conformational changes of the molecule upon substitution by a methyl group. 1-Bromo-1-methylcyclohexane is also an ionizing reagent, which means it can cause electrophilic reactions to occur on other molecules. It has been found that the solvent effect on this product can affect its reactivity, with solvents such as water having more of an effect than solvents such as benzene. 1-Bromo-1-methylcyclohexane has been shown to interact with other compounds in both transfer and complex
