Arsenazo III is a metal-binding dye that has been shown to bind to the cytosolic calcium ion. The binding of Arsenazo III to calcium has been shown to inhibit the voltage-dependent calcium channels, leading to a decrease in cytosolic calcium concentration. This reduction in cytosolic calcium is associated with energy metabolism and human serum titration calorimetry experiments. The binding of Arsenazo III to calcium is also responsible for its light signal. Arsenazo III binds to copper chloride and forms an insoluble precipitate when reacted with acidic solutions. This reaction can be used for analytical purposes as it produces a quantifiable end-point with plasma mass spectrometry.

4-Borono-L-phenylalanine is a boron-containing compound that has been used to study the biological effects of radiation. 4-Borono-L-phenylalanine is an analytical tool for measuring neutron scattering and other physical properties. It has also been used as a biochemical probe in studies of DNA duplexes. 4-Borono-L-phenylalanine is toxic to cells, inhibiting protein synthesis, and it can induce apoptosis in tumor cells. In experimental models, 4-borono-L phenylalanine can be administered orally or intravenously and has shown acute toxicity in animals at doses of up to 1000 mg/kg body weight.

Lithium tetraborate (LiBO) is a compound used in the preparation of samples for laser ablation. It can be synthesized by reacting lithium carbonate with boron nitride in a hydrochloric acid solution at room temperature. Lithium tetraborate is often used as a buffer to increase the pH of the solution and to maintain it at a constant level during reactions. This compound has been studied extensively, and its spectroscopic properties have been well documented. The thermal expansion coefficient of LiBO is high, which makes it suitable for use in radiation experiments. Lithium tetraborate has also been shown to be an effective catalyst for organic synthesis reactions that require high activation energies, such as the synthesis of phenol from benzene and formaldehyde.

Fmoc-O-tert-butyldimethylsilyl-L-serine is a monomer that can be used in the solid-phase synthesis of conjugates. It has been shown to be an efficient method for synthesizing bioconjugates, which are used in chemical biology and biotechnology. Fmoc-O-tert-butyldimethylsilyl-L-serine is also efficient for the synthesis of proteins, small organic molecules, and carbohydrates. This monomer is often used as a building block for peptide synthesis because it can be easily removed from the peptides with trifluoroacetic acid or other acid catalysts.
