4-Bromophenacyl-trifluoromethanesulfonate is a human urine metabolite that can be used as a diagnostic marker for propionylcarnitine deficiency. It is formed by the reaction of propionylcarnitine with trifluoromethanesulfonic acid, which is catalyzed by dehydrogenase enzymes. The presence of 4-bromophenacyl-trifluoromethanesulfonate in urine can also be used to diagnose magnesium oxide deficiency and acidemia, which may be due to homogenates (a type of enzyme) or a hydroxylase deficiency.

3-Mercapto-1,2-propanediol is a sulfhydryl compound that has anti-tumor properties. It has been shown to induce apoptosis in leukemia cells and to inhibit the growth of myeloma cells. 3-Mercapto-1,2-propanediol has also been shown to induce redox potentials in cancer cells and prevent the formation of disulfide bonds in the cytoskeleton. The molecular pathogenesis of cancer is thought to be related to oxidative stress, which may be prevented by 3-mercapto-1,2-propanediol. This drug has also been shown to block transfection experiments with pemetrexed in a model system and human serum.

2,2-Dimethylvaleric acid is a fatty acid that can be synthesized from 2,2-dimethylolpropane. It has been shown to reduce blood pressure in mice by inhibiting the synthesis of certain fatty acids. The mechanism of action may be due to the inhibition of messenger RNA (mRNA) and protein synthesis in the central nervous system. 2,2-Dimethylvaleric acid has also been shown to have neurotrophic effects on cultured cells and is an effective antioxidant. This compound has been used as a control for diode experiments in optical systems.

Bicyclohexyl is used as process media or solvent in many industries including chemicals, petrochemicals, polymers, coatings, photography. And it is also used to produce 1-fluorobicyclohexyl at temperature of -75°C. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

1-Hydroxycyclopropane-1-carboxylic acid is a five-membered ring compound that has been shown to be an optical isomer of cyclopropane-1,1-dicarboxylic acid. The synthesis of 1-hydroxycyclopropane-1-carboxylic acid was achieved by the reaction of acetone with chloroacetyl chloride in the presence of sodium methoxide in methanol and resulted in the formation of six stereoisomers. The E and Z isomers are known to be active as receptor ligands. The sample preparation for 1-hydroxypentane-1,5-dicarboxylic acid was carried out by dissolving it in dichloromethane. This compound can be used as potential drugs for treatment of fatty acids oxidation or metabolism disorders.

11-Mercaptoundecanoic acid (11MUA) is a fluorescence probe that reacts with the amide group of proteins. It has been used to study HIV-1 infection and the early stages of human immunodeficiency virus (HIV) replication. 11MUA can be detected by fluorescence spectrometry and gives a strong, selective signal in human serum. This compound is also used as a model system for studying protease activity and electrochemical impedance spectroscopy. 11MUA is stable in solution and can be detected at very low levels, making it an excellent probe for protein degradation studies. The reaction solution containing 11MUA can be prepared using trifluoroacetic acid (TFA), which facilitates the formation of esters from carboxylic acids, or by adding TFA to an acyl chloride derivative of 11-mercaptoundecanoic acid.
