Category. v. t. e. Forensic chemistry is the application of chemistry and its subfield, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials found at a crime scene. [1] Specialists in this field have a wide array of methods and instruments to help identify unknown substances.
Friedrich Wöhler. Friedrich Wöhler (German: [ˈvøːlɐ]) FRS (For) Hon FRSE (31 July 1800 – 23 September 1882) was a German chemist known for his work in both organic and inorganic chemistry, being the first to isolate the chemical elements beryllium and yttrium in pure metallic form. He was the first to prepare several inorganic compounds ...
t. e. Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1] Study of structure determines their structural formula.
Bromine test. In organic chemistry, the bromine test is a qualitative test for the presence of unsaturation (carbon-to-carbon double or triple bonds), phenols and anilines. An unknown sample is treated with a small amount of elemental bromine in an organic solvent, being as dichloromethane or carbon tetrachloride. Presence of unsaturation and ...
Isothermal Kovats retention index. The Kovats index applies to organic compounds. The method interpolates peaks between bracketing n -alkanes. The Kovats index of n-alkanes is 100 times their carbon number, e.g. the Kovats index of n - butane is 400. The Kovats index is dimensionless, unlike retention time or retention volume.
The Beilstein database is a database in the field of organic chemistry, in which compounds are uniquely identified by their Beilstein Registry Number.The database covers the scientific literature from 1771 to the present and contains experimentally validated information on millions of chemical reactions and substances from original scientific publications.
Identification of the ring or chain with the maximum number of senior groups. Identification of the ring or chain with the most senior elements (In order: N, P, Si, B, O, S, C). Identification of the parent compound. Rings are senior to chains if composed of the same elements. For cyclic systems: Identification of the parent cyclic ring.
In 1834, Théophile-Jules Pelouze distilled tartaric acid and isolated glutaric acid and another unknown organic acid. Jöns Jacob Berzelius characterized this other acid the following year and named pyruvic acid because it was distilled using heat. [5] [6] The correct molecular structure was deduced by the 1870s. [7]
