2,4-Dibromo-5-methoxyaniline is an analog of 2,4-diaminopyridine. It is a synthetic compound that can be prepared by catalytic reduction of the corresponding bromide. The yields are between 60 and 90%. It is used as a precursor to make other compounds such as methoxybenzene and 4-bromo-2,6-dimethoxyphenol. The compound has two methoxy groups and two hydroxy groups that can be substituted with dialkoxy or alkoxy groups. This compound also undergoes debromination to form 2,4-dibromo-5-(hydroxymethyl)aniline. 2,4-Dibromo-5-(hydroxymethyl)aniline can be oxidized to form aniline or reduced to form dihydroxybenzene (1,3).

7-Chloroquinoline-4-carbaldehyde is an intermediate in the synthesis of quinolines. It is a functionalized, hydroxylated compound that can be used as an antiproliferative reagent. 7-Chloroquinoline-4-carbaldehyde has been shown to inhibit the growth of leukemia cells, prostate cancer cells and breast cancer cells. The hydroxyl group on this molecule reacts with electrophiles to form covalent adducts and undergoes substitution reactions with amino groups. This molecule also has an aryl group that can be modified to create bioisosteres.

4-Benzylphenylmethanol is a natural compound that belongs to the class of amines. It is found in pyrethrum, which is derived from plants of the genus Chrysanthemum. 4-Benzylphenylmethanol has been used as a supplement for insect control, usually as an additive to natural pyrethrins. This substance has been shown to be effective against insect species such as the German cockroach, the fruit fly, and the mosquito. 4-Benzylphenylmethanol also has insecticidal properties by preventing insects from breaking down the chemical bonds in their cell membranes. This allows for more rapid death of insects and lessens their ability to regenerate cells after contact with this substance.

5-Nitro-1,3-benzoxazole-2-carbonitrile is a chemical compound that inhibits the uptake of drugs into cells. It is a selective inhibitor of the enzyme adenosine transporter (AT) which prevents the uptake of adenosine and other compounds into cells. The inhibition is reversible under conditions where ATP levels are low. 5-Nitro-1,3-benzoxazole-2-carbonitrile has been shown to be stable when exposed to human serum and can be used for sample preparation prior to analysis with high performance liquid chromatography (HPLC). This agent has also been shown to inhibit theophylline uptake in human erythrocytes, making it a useful tool for studying drug interactions. 5NBB also inhibits caffeine uptake in microspheres and can be used as an analytical reagent for determining caffeine content in beverages.

2-Hydroxy-2-phenylbutanoic acid is a ligand that can bind to metal ions. It has a molecular electrostatic potential of -0.07 and a low vibrational frequency of 0.01. It has been shown that this ligand can be immobilized on surfaces where it can be used for the determination of amino acids, expressed proteins, and chiral compounds. This ligand has been shown to have good binding affinity for metal ions which makes it a useful tool in immobilization studies. 2-Hydroxy-2-phenylbutanoic acid is an amide that contains two hydroxy groups, one phenyl group, and one carboxylic acid group. It is also chiral due to its asymmetric carbon atom which means that there are two different forms of the molecule, one being levorotary (R) and the other being dextrorotary (S). The functional theory shows that 2-hydroxy-2

1-Chloro-4-(iodomethyl)benzene (1CI) is a chlorinating agent that is used to produce aliphatic chlorinated compounds. It can be used for the alkylation of alcohols, as well as the chlorination of halides. 1CI has been shown to react with benzene in a synergistic manner when irradiated. In addition, it can be used for the preparation of iodides by reacting with sodium or potassium iodide in the presence of an alcohol and a catalyst. 1CI reacts with chloride ions to produce cyclic compounds in the microwave region. The reaction requires an electron transfer agent, such as copper chloride or silver nitrate, and yields are dependent on the type of alcohol used, which can be either aliphatic or cyclic.
