Ammonium carbonate is an inorganic salt that consists of ammonium ion and carbonate ion. It is a white crystalline solid with a molecular weight of about 166.4 g/mol. Ammonium carbonate is soluble in water, alcohol, acetone, and other organic solvents. It has been used as a buffer solution for pH adjustment and as a source of ammonium ions in analytical chemistry. Ammonium carbonate can be formed by the reaction of sodium carbonate with ammonia gas or liquid ammonia, or the reaction of sodium bicarbonate with ammonia gas or liquid ammonia. The thermal expansion coefficient of ammonium carbonate is higher than those of sodium salts such as sodium chloride and potassium chloride. Electrochemical impedance spectroscopy (EIS) measurements have shown that the reactivity between ammonium carbonate and plasma mass spectrometry is high due to its high values on the electric spectrum graph at low frequencies (1 kHz).

Tetramethylrhodamine isothiocyanate - mixed isomers (TMR-MI) is a fluorescent probe that can be used to study the interactions between cells and particles. TMR-MI binds to DNA and RNA molecules and has been used as a model system for studying enzyme inhibition. TMR-MI has also been shown to inhibit bowel disease in animal models, but it is not specific to any one cell type. This compound has been used extensively in biomedical research, including studies of autoimmune diseases, cancer, and tissue culture. It has also been used as a marker for detecting reactive oxygen species in laser ablation experiments in mitochondria. TMR-MI can be used to enhance the detection sensitivity of analytical chemistry measurements.

2-(Dimethylamino)ethanol is a colorless liquid that has a molecular weight of 78.1 g/mol and a boiling point of 176.1 °C. It can be found in many household products as well as cosmetics, pharmaceuticals, and chemical manufacturing. 2-(Dimethylamino)ethanol is a precursor to acetaldehyde and acetic acid, which are important intermediates in the production of polymers such as nylon. It can also be used to synthesize other chemicals such as dimethylformamide, ethylene glycol, and methyl methacrylate. This chemical reacts with calcium to form insoluble calcium 2-(dimethylamino)ethanolate (Ca(DMAE)). This reaction is reversible and the equilibrium can be shifted by changing the pH or adding another reactant such as hydrogen peroxide or hydroxide ions.

(R)-(-)-2-Amino-1-butanol is an organic compound that is used as a reagent in the synthesis of pharmaceuticals. It has antimycobacterial properties and can be used to treat tuberculosis. The mechanism for its antimycobacterial activity is not fully understood, but it may involve copper complex formation with the mycobacteria. The chloride ion may also play a role in this process by binding to the copper complex and increasing its solubility in water. This compound may react with aminothiols from the host cell, leading to degradation of DNA, RNA, and proteins. (R)-(-)-2-Amino-1-butanol has been shown to have cytotoxic effects on colorectal adenocarcinoma cells and human lung cancer cells in culture. It also inhibits human colon carcinoma cells in culture through the production of organic acids such as formic acid and acetic acid.

<p>(2H-Tetrazol-5-yl)methylamine is a sweetener that has been used as an analog of saccharin. It is not approved for use in the United States. The sweetness of (2H-tetrazol-5-yl)methylamine is due to its interaction with sodium ions, which make it a sodium salt. This compound is not sweet by itself but it does have optical properties that can be used to measure the concentration of sodium ions in solution. The chemical structure of (2H-tetrazol-5-yl)methylamine consists of a tetrazole group, an amine group and two methyl groups.</p>

Gamma-aminobutyric acid (GABA) is a neurotransmitter that inhibits the transmission of nerve impulses in the brain. GABA binds to specific receptors and blocks voltage-dependent calcium channels, which are ion channels that allow the passage of calcium ions into cells. GABA also has a number of other functions, including biochemical properties, its role in brain function and drug interactions. The GABA receptor is found on neurons and is subject to modulation by drugs that interact with GABA receptors. In addition, GABA can react with water vapor to produce hydrogen bonding interactions. This reaction is used in electrochemical impedance spectroscopy as an analytical tool for determining the concentration of free water in a sample.
