3-Benzyloxy-phenyl)hydrazine hydrochloride is a chemical used in the synthesis of other organic compounds. It is a versatile building block that can be used in the preparation of complex compounds and useful intermediates. 3-Benzyloxy-phenyl)hydrazine hydrochloride is an excellent reagent for reactions involving electron-deficient alkenes, alkynes, and cyclic ethers. This compound also has applications as a pharmaceutical intermediate and as an analytical reference standard for chemical analyses.

(4-Iodophenyl)hydrazine hydroiodide is a synthetic compound that has shown anti-viral activity against HIV and cytomegalovirus. It also has anticancer properties and can be used to treat colon cancer. The compound binds to the nucleic acid in a number of ways, including by forming reversible covalent bonds with functional groups on the nucleic acid. These interactions are primarily due to its pyrazole ring and hydrazine moiety. (4-Iodophenyl)hydrazine hydroiodide is structurally similar to phenyldiazenyl, which exhibits photochromism and fluorescence properties. This similarity may account for the observed photochemical changes in the molecule when exposed to light.

3,5-Dimethylphenylhydrazine hydrochloride is a chemical compound that is used as a reagent in biochemistry and molecular biology. It reacts with proteins to form stable covalent bonds. This reaction can be used to modify the active site of an enzyme or to create affinity labels for protein purification. 3,5-Dimethylphenylhydrazine hydrochloride can also react with a pyrrole group on the side chain of phenylalanine residues to form an affinity label that allows it to bind specifically to myoglobin. The modification of myoglobin alters its structure and its ability to bind oxygen, which results in a shift in the wavelength at which it absorbs light.

Dansyl hydrazine is a fluorescent probe that is used in the investigation of energy metabolism. It reacts with α1-acid glycoprotein, which is an important component in blood serum and urine. Dansyl hydrazine can be added to a solution containing water vapor and metabolic disorders to produce a fluorescent signal. This reaction has been shown to be linear over a range of concentrations for both model systems and human serum. Dansyl hydrazine has also been used as an analytical method for dinucleotide phosphate and maduramicin ammonium.
Dansyl hydrazine reacts with k562 cells when it comes into contact with sugar or other biological samples containing antimicrobial agents, producing fluorescent signals.

2-Nitrophenylhydrazine is a drug that is used as an anti-inflammatory agent. It is a nonsteroidal anti-inflammatory drug (NSAID) that acts by blocking the production of prostaglandins in the body, preventing inflammation and pain. 2-Nitrophenylhydrazine can be used to treat conditions such as arthritis, gout, and rheumatoid arthritis. This drug also has the ability to remove organic contaminants from water. 2-Nitrophenylhydrazine binds with fatty acids in wastewater treatment plants, forming an insoluble complex that precipitates out of solution. The compound inhibits the activity of hydrogen bond and methyl ethyl groups, which are needed for the biosynthesis of polyunsaturated fatty acids like phytanic acid and diphenyl ether.
