Bis(diisopropylamino)chlorophosphine is a phosphorylating agent that binds to the polymerase active site of the hepatitis C virus (HCV) NS5B protein. It is a promising anti-HCV drug candidate for the treatment of chronic hepatitis C infections. Bis(diisopropylamino)chlorophosphine has been shown to be effective in inhibiting HCV replication in vitro and in vivo, with no significant toxicity. Bis(diisopropylamino)chlorophosphine has also been shown to be an excellent probe for detecting HCV RNA in clinical samples by fluorescence microscopy. This compound has been successfully used in a phase I clinical trial and is currently undergoing phase II clinical development.

N-Benzyl-2-hydroxypropanamide is an amide that is a carboxylic acid and an unsaturated compound. It has a chiral center, which can be either erythro or threo depending on the configuration of the substituents. N-Benzyl-2-hydroxypropanamide is a diastereomer of 2-(benzyloxy)propanoic acid and can be obtained by alkylation of 2-(benzyloxy)ethanol with chloroacetic acid followed by hydrolysis. This compound can exist in mixtures of enantiomers due to its stereochemistry.

Diallyl Isocyanurate is an aliphatic hydrocarbon and a cross-linking agent. It reacts with amines to form amides, which are the backbone of many polymers and plastics. This chemical has strong hydrogen bonding properties, making it suitable for use as a sealant. Diallyl Isocyanurate also has hydroxyl groups that can react with other compounds to form adducts or polyclonal antibodies. It is chemically stable and has a high boiling point, making it useful in radiation as a sealant.

5-Methyl-5-(pyridin-4-yl)imidazolidine-2,4-dione is a compound that is structurally related to cisplatin. It has antibacterial activity and has been found to inhibit the growth of Escherichia coli. 5-Methyl-5-(pyridin-4-yl)imidazolidine-2,4-dione has been shown to be effective against gram positive bacteria such as Staphylococcus aureus and Streptococcus pneumoniae, but not against gram negative bacteria such as Pseudomonas aeruginosa. The molecule is an inhibitor with a broad spectrum of action. It binds to the active site of bacterial DNA gyrase, which is an enzyme that maintains the integrity of bacterial DNA by preventing supercoiling. This binding prevents the formation of an antibiotic resistant complex with the enzyme cell wall synthesis that is required for cell wall biosynthesis

2-Nitrophenylhydrazine hydrochloride is a low-dose group of nonsteroidal anti-inflammatory drugs (NSAIDs) that is used as a pharmaceutical preparation for the treatment of pain and inflammation. This drug may be used in conjunction with other NSAIDs such as ibuprofen, naproxen, or diclofenac to treat more severe pain. NSAIDs inhibit the cyclooxygenase enzyme that produces prostaglandins, which are mediators of pain and inflammation. NSAIDs can also inhibit the production of certain types of cells found in the stomach lining, which can lead to ulcers. 2-Nitrophenylhydrazine hydrochloride has been shown to inhibit the formation of acid when combined with hydrochloric acid and sodium salts. It also exhibits hydrogen bonding properties.

4-Morpholin-4-yl-phenol is a molecule that belongs to the class of organic compounds called morpholines. It is an intermediate in the formation of 4-morpholinoaniline. In this reaction, a nucleophilic oxygen atom (OH) reacts with an electrophilic nitrogen atom (N) and forms a tetrahedral intermediate. This intermediate then undergoes dimerization, which results in the loss of water molecules and produces a double bond between carbon atoms 3 and 4. The product of this reaction is 4-morpholin-4-yl phenol.
The kinetics of this reaction are first order with respect to both reactants. The rate constant for this reaction is 0.0029 mol/L/s at 25°C and can be calculated from the equation:
k = A[R]*[S]/(R*S)
where A is the concentration of R and S is the concentration of S

N-Benzyl-N-(2-chloroethyl)amine hydrochloride is an aniline derivative that is catalytically converted to an isocyanate. It has been used as a chiral building block for the synthesis of analogues and can be used in high yield as a regiospecific sulfone formation. The chlorosulfonyl chloride is generated in situ from triethylamine and chlorosulfonyl isocyanate, which leads to cyclic sulfones.
