  2. Amine - Wikipedia

    en.wikipedia.org/wiki/Amine

    Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...

  3. Aliphatic compound - Wikipedia

    en.wikipedia.org/wiki/Aliphatic_compound

    Most aliphatic compounds are flammable, allowing the use of hydrocarbons as fuel, such as methane in natural gas for stoves or heating; butane in torches and lighters; various aliphatic (as well as aromatic) hydrocarbons in liquid transportation fuels like petrol/gasoline, diesel, and jet fuel; and other uses such as ethyne (acetylene) in welding.

  4. Aromatic amine - Wikipedia

    en.wikipedia.org/wiki/Aromatic_amine

    In organic chemistry, an aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines, but also many more complex aromatic rings and many amine substituents beyond NH 2. Such compounds occur widely. [1]

  5. Aromatic amino acid - Wikipedia

    en.wikipedia.org/wiki/Aromatic_amino_acid

    Aromatic trace amines like tyramine can displace norepinephrine from peripheral monoamine vesicles and in people taking monoamine oxidase inhibitors (MAOIs) this occurs to the extent of being life threatening. Blue diaper syndrome is an autosomal recessive disease that is caused by poor tryptophan absorption in the body.

  6. Sympathomimetic drug - Wikipedia

    en.wikipedia.org/wiki/Sympathomimetic_drug

    A primary or secondary aliphatic amine separated by 2 carbons from a substituted benzene ring is minimally required for high agonist activity. The pKa of the amine is approximately 8.5-10. [2] The presence of hydroxy group in the benzene ring at 3rd and 4th position shows maximum alpha- and beta-adrenergic activity. [medical citation needed]

  7. Proline - Wikipedia

    2 but is rather a secondary amine. The secondary amine nitrogen is in the protonated form (NH 2 +) under biological conditions, while the carboxyl group is in the deprotonated −COO − form. The "side chain" from the α carbon connects to the nitrogen forming a pyrrolidine loop, classifying it as a aliphatic amino acid.

  8. Amine oxide - Wikipedia

    en.wikipedia.org/wiki/Amine_oxide

    Almost all amine oxides are prepared by the oxidation of either tertiary aliphatic amines or aromatic N-heterocycles. Hydrogen peroxide is the most common reagent both industrially and in academia, however peracids are also important. [6] More specialised oxidising agents can see niche use, for instance Caro's acid or mCPBA. Spontaneous or ...

  9. Diethyl toluene diamine - Wikipedia

    en.wikipedia.org/wiki/Diethyl_toluene_diamine

    There are other more specialist uses for the material too. [15] As it is an aromatic amine, its rate of cure is much slower than aliphatic amines and thus used with epoxy resin systems to lengthen the working time or potlife. [16] These are then used in adhesives, sealants, and paints or coatings. [17]
