<p>N-Cyanopiperidine is a cyclohexane ring with a trifluoroacetic acid group. It is used in the synthesis of pharmaceutical preparations and has been shown to be stable in low-energy environments, such as when mixed with glycol ethers or chlorides. N-Cyanopiperidine is also used as an intermediate for the preparation of other compounds, such as metal carbonyl complexes and derivatives. N-Cyanopiperidine can be synthesized by reacting anhydrous hydrogen cyanide with piperidinium chloride in the presence of metal hydroxides. This reaction mechanism is known to produce two products: 1) a stable complex with a metal ion, and 2) a reaction product that contains the desired product and hydrogen cyanide.</p>

<p>3-Cyanocinnamic acid is a reactive, unreactive, and stepwise cycloaddition compound. It can participate in photochemical reactions with other compounds to form photodimers. 3-Cyanocinnamic acid has an optimal reaction temperature of 100°C and a reaction time of 5 minutes. The diradical nature of 3-cyanocinnamic acid makes it sensitive to UV light, and the photochemical reactions are simulated by quantum mechanics calculations. Photodimerisation simulations show that 3-cyanocinnamic acid is capable of forming photodimers with 2-cyanocinnamic acid or 4-cyanocinnamic acid at room temperature.</p>

<p>2-(4-tert-Butyl-phenoxy)acetonitrile is a high quality, reagent, complex compound that is useful as a building block in the synthesis of fine chemicals and speciality chemicals. 2-(4-tert-Butyl-phenoxy)acetonitrile can be used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals. It has a CAS number of 50635-24-0. This chemical is also useful for research purposes.</p>

<p>2-Cyanoacetamide is an organic compound that is used in pharmaceutical preparations. It reacts with malonic acid to form a dioxime, which is a precursor of various drugs. The optimum concentration for the reaction to occur is at 10% (w/v). The reaction mechanism has not been fully elucidated and it involves the transfer of nitrogen from an amide group to a carbonyl group. 2-Cyanoacetamide has shown anti-angiogenic effects in mice by inhibiting the expression of Mcl-1 protein, which is involved in the regulation of apoptosis and inflammation. This drug also has biological functions as a precursor for dopamine, which helps regulate motor and cognitive functions.</p>

<p>2-Hydroxy-4-nitrobenzonitrile is a nitrile derivative that has an antibacterial activity. This compound interacts with the pyochelin, a siderophore in Pseudomonas aeruginosa. The antibiotic inhibits the uptake of pyochelin by the bacteria and causes cell death by inhibiting the synthesis of proteins necessary for bacterial growth. 2-Hydroxy-4-nitrobenzonitrile can be used as a potential stabilizer for materials such as polystyrene and polyurethane which are susceptible to degradation by hydrolysis or oxidation. In addition, this compound is also useful in gram-negative bacterium due to its ability to inhibit their growth by binding to their ribosomes. The conformational studies have been shown to be important for understanding the biological properties of this molecule.</p>
