4-Amino-3-nitrophenol is a reactive aminophenol that can be synthesized from hydrogen sulfate and diethyl ester. It is used in the synthesis of amines and other chemicals, as well as in analytical methods for determining the concentration of nitrates, nitrites, and aminophenols. 4-Amino-3-nitrophenol has been shown to have photocatalytic activity.

WST-1 is a water soluble cell permeable dye.  Upon NADH-dependent enzymatic cleavage by cellular mitochondrial dehydrogenases, formazan is released, which can be quantified by colorimetric detection at 450 nm.

Glycerin rosin ester is a polyunsaturated, hydrogenated, fatty acid that is used as a cross-linking agent. It is a mixture of glycerin and calcium stearate with traces of choroidal neovascularization. Glycerin rosin ester is used in the production of pharmaceutical preparations to increase the viscosity and stability of the formulation. Glycerin rosin ester has been shown to have a low thermal expansion coefficient, which allows it to be used as a hydrogen bond. This product also has an allergic effect on skin and can cause irritation if touched or inhaled. The transport rate for this product is 0.5 kilometers per hour at 20 degrees Celsius.

3'-Amino-2'-hydroxyacetophenone is a synthetic compound that reacts with salicylaldehyde and hydrochloric acid to form an aromatic hydrocarbon. The reaction vessel used is made of glass and contains potassium dichromate, copper complex, and nitro. This product can be produced in acidic conditions with the addition of phosphotungstic acid and chloride. 3'-Amino-2'-hydroxyacetophenone can also be produced by reacting mercuric chloride, which is an oxidizing agent, with an aromatic hydrocarbon. This product has a rotator.

3,3',5,5'-Tetraiodo-L-thyronine sodium hydrate is a synthetic thyroid hormone that is used to treat hypothyroidism and myxedema coma. It is also used as an ingredient in pharmaceuticals. 3,3',5,5'-Tetraiodo-L-thyronine sodium hydrate has been shown to be effective in the treatment of hypothyroidism and myxedema coma. The drug exhibits a high degree of bioequivalence with levothyroxine sodium tablets.
MRP2/ABCG2 transport proteins are expressed at high levels in the liver and gut epithelium and play a role in the absorption of 3,3',5,5'-tetraiodo-L-thyronine sodium hydrate from the small intestine into blood circulation. This drug binds to sorbitol and d-mannitol through hydrogen bonding interactions. These interactions may be responsible for

Phytosterols are a group of plant-derived sterols that have been shown to have cholesterol-lowering activity in humans. The cholesterol-lowering effect is due to the ability of phytosterols to bind with cholesterol receptors and inhibit the absorption of dietary cholesterol. Phytosterols are absorbed from the small intestine into the blood, where they are converted into bile acids and eliminated in stool. Phytosterols also have anti-inflammatory properties, which is thought to be due to their ability to inhibit prostaglandin synthesis. Phytosterols may also protect against atherosclerosis by inhibiting LDL oxidation and reducing inflammatory cell recruitment. The following products are designed for use as pharmaceuticals:

2,2'-Biphenol is a phenolic compound that is used in the synthesis of polymers. The thermal expansion coefficient of 2,2'-biphenol can be measured by DSC and found to be ˜6.5 × 10−4/°C. The UV absorption spectrum of 2,2'-biphenol shows three bands at wavelengths of 290 nm, 320 nm, and 370 nm. 2,2'-Biphenol has been shown to adsorb onto biological surfaces through an adsorption mechanism. It has been observed that this adsorption occurs via x-ray crystal structures and kinetic measurements have shown that the adsorption process is rate-limited by intramolecular hydrogen bonding between the protonated phenolic hydroxyl group and the aromatic ring. The activation energies for protonation and desorption have been determined to be ˜30 kJ/mol and ˜30 kJ/mol respectively. Ac
