Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C 14 H 10, consisting of three fused benzene rings. It is a component of coal tar.Anthracene is used in the production of the red dye alizarin and other dyes, as a Scintillator to detect high energy particles, as production of pharmaceutical drugs.
9,10-Dihydroxyanthracene is an organic compound with the formula C 14 H 10 O 2.It is the hydroquinone form of 9,10-anthraquinone (AQ). It formed when AQ is hydrogenated. [1] It is easily dissolved in alkaline solutions and is often called soluble anthraquinone (SAQ).
Heteroarenes are aromatic compounds, where at least one methine or vinylene (-C= or -CH=CH-) group is replaced by a heteroatom: oxygen, nitrogen, or sulfur. [3] Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one ...
The Biopharmaceutics Classification System (BCS) is a system to differentiate drugs on the basis of their solubility and permeability. [1] This system restricts the prediction using the parameters solubility and intestinal permeability. The solubility classification is based on a United States Pharmacopoeia (USP) aperture.
A 3D model of ethylene, the simplest alkene. In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon–carbon double bond. [1] The double bond may be internal or in the terminal position.
This is evidently an alternative definition of Wirtinger derivative respect to the complex conjugate variable: [10] it is a more general one, since, as noted a by Henrici (1993, p. 294), the limit may exist for functions that are not even differentiable at =. [11] According to Fichera (1969, p. 28), the first to identify the areolar derivative ...
The provitamin beta carotene is a terpene derivative called a carotenoid. The steroids and sterols in animals are biologically produced from terpenoid precursors. Sometimes terpenoids are added to proteins, e.g., to enhance their attachment to the cell membrane; this is known as isoprenylation.
