2,4-Dichloroaniline is an organic compound that is used in analytical chemistry for the preparation of samples. 2,4-Dichloroaniline reacts with p-hydroxybenzoic acid to form a diazonium salt. This reaction takes place at room temperature and produces a deep violet color. The detection sensitivity of this reaction is 0.1 µg/mL. The glucuronide conjugate of 2,4-dichloroaniline has been detected in human urine samples and can be used as a marker for exposure to this chemical. 2,4-Dichloroaniline also inhibits protein synthesis by binding to amines or by affecting the availability of the amino acids required for protein synthesis. The hydrochloric acid present in stomachs converts 2,4-dichloroaniline into phenylglyoxylic acid, which is then excreted in the urine as its glucuronide conjugate

2-Chloro-5-fluoropyridine-3-carboxylic acid is an intermediate in the synthesis of fluorine compounds used in the industrial process. It can be synthesized by chlorinating 5-fluoropyridine with chlorine gas and a catalyst such as platinum, or by hydrogenating 2-chloro-5-pyridinecarboxylic acid. This chemical is used to manufacture other chemicals such as ethylene oxide, tetrafluoroethylene, and hexafluoroethane.

2-(2-Chlorophenyl)ethanol is a chemical used to synthesize aldehydes and fatty acids. It is also used to validate the purity of products, such as bulk drugs. 2-(2-Chlorophenyl)ethanol can be found in solvents, impurities, and chlorobenzene. It is not recommended for use at temperatures above 50°C or below -10°C. This chemical should not be left in contact with plastic or rubber tubing for extended periods of time because it may cause discoloration or cracking. 2-(2-Chlorophenyl)ethanol is not radioactive, but it may become so after irradiation.

Betaine hydrochloride is a betaine prodrug that is metabolized by the body to form glycine and choline. Betaine hydrochloride has been shown to have anti-inflammatory properties, which may be due to its ability to inhibit surfactant sodium dodecyl (SDS) from activating enzymes such as polymerase chain reaction (PCR). Betaine hydrochloride also has been shown to improve disease activity in bowel disease patients and can be used as a dietary supplement for individuals with low levels of choline.

3',5'-Difluoroacetophenone is a synthetic compound that belongs to the tetradentate class of ligands. It is used as a fluorescent probe for metal ions and has been shown to have thermodynamic, systematic, and biomolecular enhancement properties. 3',5'-Difluoroacetophenone has also been used as a fluorescent probe in fluorescence resonance energy transfer (FRET) experiments. 3',5'-Difluoroacetophenone binds to metal cations, such as copper(II) ions. When this compound is protonated, it emits a strong fluorescence signal that can be detected by fluorophore-acceptor probes. This chemical can be orally taken and excreted in urine after metabolism by the liver and kidneys.

5-Chloro-1H-indol-3-ylamine (5CI) is a chemical that has been shown to have antitubercular and antifungal properties. It is a potent inhibitor of mycobacterium tuberculosis, inhibiting the growth of mycobacterium tuberculosis at concentrations as low as 10 micrograms per milliliter. 5CI also has antibacterial activity against various strains of bacteria and antimicrobial activity against various strains of fungi. 5CI was shown to be more active than isoniazid in inhibiting the growth of Mycobacterium tuberculosis.
