1,2,4,5-Tetrabromobenzene is a brominated organic compound that forms a palladium complex. It has been studied by chemical ionization with an atmospheric pressure photoionization detector (APPI) and molecular modeling. The debromination reaction of 1,2,4,5-tetrabromobenzene was observed to take place in the liquid phase at room temperature. The detection limit for this reaction was found to be between 0.1 and 5 ppm. The most common form of 1,2,4,5-tetrabromobenzene is the monoclinic polymorph; however it can also exist as a trigonal system or as a hexagonal system when heated above its phase transition temperature. This compound is soluble in water and mercury chloride solutions but insoluble in ethers or chloroform.

2-Bromo-1,3-diethylbenzene is a reactive intermediate that can be used for the synthesis of styrene derivatives. It is also used as an anesthetic agent and has been shown to have cognition-enhancing properties. This compound reacts with electrophiles to form monoadducts, which are useful for protein targetting. The pharmacophore of 2-bromo-1,3-diethylbenzene consists of vinyl groups and halides. Radiation induces substitution reactions on the vinyl groups. Pharmacophores are important in drug design because they help identify specific chemical features that are necessary for binding to a particular protein target or protein targets.

1-Bromo-2-chloro-3-fluorobenzene is a halide of fluorine and chlorine. It is used in the production of biphenyls and fluoroarenes. 1-Bromo-2-chloro-3-fluorobenzene has anticarcinogenic properties in animal studies, but it can be toxic to humans. Exposure to 1-bromo-2,3 difluorobenzene may lead to neurological, respiratory, hepatic, ocular, and gastrointestinal toxicity. This compound also has been shown to affect the liver enzymes as an enzyme inducer and is believed to be carcinogenic in animals.

1,4-Dimethoxy-2-fluorobenzene is a synthetic molecule that belongs to the class of halides. It is used as a ligand in X-ray crystallography and has been shown to have anti-cancer properties. 1,4-Dimethoxy-2-fluorobenzene can be prepared by reacting primary amines with chloroformates in the presence of bases at temperatures between -20 °C and 100 °C.

2-Bromo-1,3,5-triisopropylbenzene is an ethylene acetal that is prepared by the catalyzed reaction of aryl chlorides and anhydrous zinc bromide in the presence of triethylamine. The selectivities of this method are high because it can produce mainly a single isomer. The stereoselectivity is also high because the reaction proceeds with the formation of only one stereoisomer. The mechanism for this reaction involves a nucleophilic substitution of the halogenated aryl chloride with the trialkylborane, which generates two different products. This product has been used in the synthesis of biphenyls and nitro compounds.

4-Toluenesulfonylmethylisonitrile is a potent antagonist of the malonic acid receptor that has been shown to be reactive. It is synthesized by reacting methyl ketones with trifluoroacetic acid and nitrogen gas in the presence of a catalyst. The reaction mechanism has been studied using gravimetric analysis and the thermodynamic data have been calculated for fatty acids. 4-Toluenesulfonylmethylisonitrile can be used to make esters.

4-Acetamidobenzenesulfonyl azide (4ABS) is a low detection reagent that can be used for the determination of 4-acetamidobenzoic acid. It reacts with the amine group in 4-acetamidobenzoic acid to form a sulfonamide intermediate and releases an azide ion. The linear calibration curve was obtained using vibrational spectroscopy and has a detection sensitivity of 0.03 ppm. This method can also be used to determine the functional groups present in dopamine, which have been shown to affect electrochemical impedance spectroscopy measurements.

4-Chlorobenzenethiol is a chemical compound that contains a fatty acid. It is an intramolecular hydrogen donor with the ability to form a disulfide bond. The compound also has high stability and can be used in organic synthesis reactions involving reactive sulfur groups. 4-Chlorobenzenethiol reacts with sodium carbonate to produce sodium thiocarbonate and chloroform, which are then reacted with phosphorus pentoxide for oxidation. The reaction mechanism is similar to that of the Diels-Alder reaction and the model system involves dinucleotide phosphate. 4-Chlorobenzenethiol can be reacted with hydrochloric acid or trifluoroacetic acid as an oxidizing agent.

1-Bromo-4-iodobenzene is an aryl halide that can be synthesized by the cross coupling of ethyl formate and hydrochloric acid. This compound is useful in analytical applications, such as chromatographic methods, due to its high solubility in organic solvents. It is also used in synthetic procedures for the preparation of other aryl halides. 1-Bromo-4-iodobenzene has been used to synthesize calcium carbonate via the Suzuki coupling reaction with sodium salts, which are nucleophiles. The carbonyl group on this molecule reacts with the nucleophile, forming an alkyl group and a metal salt. Transfer reactions involving these salts can produce other products with different functional groups.
