Amodiaquine-d10 is a quinoline derivative that is used in the treatment of malaria. It has been shown to have a good bioavailability and is not metabolized by the body. Amodiaquine-d10 has a low risk of toxicity, which makes it appropriate for use in patients with an uncomplicated malaria infection. The plasma concentrations are determined through an analysis of the presence of amodiaquine-d10 in plasma samples. The pharmacokinetic study was performed using an ionization interface and a spectrometer. The evaporation technique was used to measure the concentration of amodiaquine-d10 in plasma samples, which were then analyzed using high performance liquid chromatography (HPLC). This technique allows for the measurement of amodiaquine-d10 at low concentrations and can differentiate between drugs that are chemically similar.

YD2-o-C8 is a low light, metal-coordinating organic molecule that has been shown to enhance the performance of perovskite solar cells. It is a multi-walled carbon nanotube with a metal atom at each end. The interactions between the YD2-o-C8 and the perovskite are believed to be due to an electron transfer process that takes place within the perovskite's molecular orbitals. This interaction leads to increased efficiencies in these devices.

Dideuterosulfuric acid is a protonated molecule that is found in the tropone class of organic compounds. It has been shown to have optical properties similar to those of ferrocene, which is why it is often used as a replacement for this compound. Dideuterosulfuric acid has been studied extensively using a kinetic method with the goal of determining its mechanism and rate constants. Hydroxyl groups are found on the molecule's trifluoroacetic acid side chains, which may contribute to its reactivity with chloride ions and nitrogen atoms. Electrophotographic measurements show that hydrogen bonding occurs between molecules in dilute solutions.

Rac-1,2-Bis-palmitoyl-3-chloropropanediol (rac1,2BPC) is a dispersive compound that has been used in the experimental phase of extraction. It has been shown to be efficient in the quantification and screening of fatty acids. Rac1,2BPC has also been used as a spiking agent for food samples to identify contaminants. The recoveries have been validated and linearity has been demonstrated. Rac1,2BPC is an anion that can be quantified by liquid chromatography with wavelength detection at 202 nm.

Alprazolam is a benzodiazepine drug used as an anxiolytic, anticonvulsant, and sedative. It is one of the most commonly prescribed drugs in the United States. Alprazolam-d5 solution is a solution that contains alprazolam labeled with D5. It can be used for wastewater treatment to identify the presence of trifluoroacetic acid (TFA) in wastewater samples. The dispersive solid-phase extraction method was validated for use with this labeled compound by detecting alprazolam-d5 at concentrations of 0.0025 µg/mL or less in urine samples within 10 minutes. Alprazolam-d5 solution has been shown to be stable in acidic pH environments and can be used for detection times up to 2 hours.

7-Hydroxy-4-cholesten-3-one-D7 (7OHCD7) is a metabolite of the bile acid, cholic acid. It is generated by the action of cholesterol 7α hydroxylase on cholesterol in the liver. It is excreted in bile, which is then absorbed back into the body from the gut and used for energy metabolism. 7OHCD7 has been shown to be an inhibitor of histone deacetylases, which are enzymes that regulate gene transcription. This inhibition leads to increased transcriptional regulation and reduced inflammatory responses in bowel disease models. 7OHCD7 has also been shown to increase cholesterol levels and reduce inflammation in humans with metabolic syndrome.
