Gentisic acid is a dihydroxybenzoic acid. It is a derivative of benzoic acid and a minor (1%) product of the metabolic break down of aspirin, excreted by the kidneys. [4] It is also found in the African tree Alchornea cordifolia and in wine. [5]
Dihydroxybenzoic acids (DHBA) are a type of phenolic acids. There are six main compounds, having all the same molecular formula C 7 H 6 O 4. Those are: 2,3-Dihydroxybenzoic acid (2-Pyrocatechuic acid or hypogallic acid) 2,4-Dihydroxybenzoic acid (β-Resorcylic acid) 2,5-Dihydroxybenzoic acid (Gentisic acid) 2,6-Dihydroxybenzoic acid (γ ...
2,5-Dihydroxy-1,4-benzoquinone or 2,5-dihydroxy-para-benzoquinone is an organic compound with formula C 6 H 4 O 4, formally derived from 1,4-benzoquinone by replacing two hydrogen atoms with hydroxyl (OH) groups. It is one of seven dihydroxybenzoquinone isomers. It is a yellow solid [1] with planar molecules [2] that exhibits ferroelectric ...

2,5-Dimethoxybenzaldehyde is an organic compound and a benzaldehyde derivative. One of its uses is the production of 2,5-dimethoxyphenethylamine, also known as 2C-H . 2C-H is used to produce many other substituted phenethylamines such as 2C-B , 2C-I and 2C-C .
Hyaluronic acid plays a very important role in the vocal fold biomechanics. In fact, hyaluronic acid has been described as the extracellular matrix molecule that not only contributes to the maintenance of an optimal tissue viscosity that allows phonation, but also of an optimal tissue stiffness that allows frequency control.

Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [1] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [2]
DOI, also known as 2,5-dimethoxy-4-iodoamphetamine or as 2,5-dimethoxy-4-iodo-α-methylphenethylamine, is a substituted phenethylamine and amphetamine derivative and a member of the DOx family of drugs. It is structurally related to the naturally occurring phenethylamine psychedelic mescaline (3,4,5-trimethoxyphenethylamine).
