2-Chloro-4-methylsulfonylbenzoic acid is a chlorinating agent that can be used to produce triketones from ketones. It is usually used as a hydrogen peroxide scavenger and a chlorinating agent in the food industry. 2-Chloro-4-methylsulfonylbenzoic acid can also be used to produce glyphosate, phosphoric acid solution, and chloride. The chlorinating property of this compound is due to its ability to form hypochlorous acid when it reacts with water. This reaction produces hypochlorite ions that are active against microorganisms by disrupting the cell membrane. 2-Chloro-4-methylsulfonylbenzoic acid can react with organic solvents such as carbon tetrachloride and optimizes the introduction of chlorine into organic compounds.

3,5-Dichlorobenzaldehyde is an organic compound with the formula CHClO. It is a colorless liquid that smells like freshly cut grass. 3,5-Dichlorobenzaldehyde is used in organic synthesis as an electrophile for the preparation of substituted benzoquinones and other heterocycles. It is also used to prepare aromatic amines via aldol condensation with ketones. In addition, it can be used to generate azides from nitroarenes or nitroalkanes in the presence of sodium azide or potassium azide. Finally, it can be used to synthesize molybdenum compounds such as molybdic acid and ammonium molybdate.

2,4-Dinitrobenzoic acid (2,4-DNBA) is a chemical reagent that has been used as a positive control for the detection of hydrogen bonding interactions. It is also used in analytical methods to detect protonation, carboxylate, and hydroxyl groups. This compound can be prepared from picric acid by nitration with nitric acid and then reacting with aniline. The 2,4-DNBA molecule contains two intramolecular hydrogen bonds and four intermolecular hydrogen bonds. 2,4-DNBA is classified as a trifluoroacetic acid derivative.

2,3,4-Trimethoxy-6-methylbenzaldehyde is a synthetic coumarin with antibacterial activity. It is synthesized by the condensation of 3-hydroxyacetophenone and benzaldehyde. 2,3,4-Trimethoxy-6-methylbenzaldehyde has been shown to have antibacterial activity against both Gram-positive and Gram-negative bacteria. This molecule has also been shown to inhibit the growth of Gram negative bacteria in the presence of hydrogen peroxide. The crystal structure of this molecule was determined by XRD analysis and shows that it contains a dihedral angle of about 155°.
