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(NH 3 (in which the bond angle between the nitrogen and hydrogen is 170°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
Free base (freebase, free-base) is a descriptor for the neutral form of an amine commonly used in reference to illicit drugs. The amine is often an alkaloid, such as nicotine, cocaine, morphine, and ephedrine, or derivatives thereof. Freebasing is a more efficient method of self-administering alkaloids via the smoking route.
Cyclohexylamine is an organic compound, belonging to the aliphatic amine class. It is a colorless liquid, although, like many amines, samples are often colored due to contaminants. It has a fishy odor and is miscible with water.

Personal flotation devices being worn on a navy transport . A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water.
Niacin, essential to many types of life, is an example of a heterocyclic amine. Heterocyclic amines , also sometimes referred to as HCA s, are chemical compounds containing at least one heterocyclic ring, which by definition has atoms of at least two different elements, as well as at least one amine (nitrogen-containing) group.
2-Aminoalcohols are an important class of organic compounds that are often generated by the reaction of amines with epoxides: C 2 H 4 O + R−NH 2 → RNHC 2 H 4 OH. Simple alkanolamines are used as solvents, synthetic intermediates, and high-boiling bases. [2] Hydrogenation or hydride reduction of amino acids gives the corresponding 2 ...
Under basic conditions in the presence of primary amines, hydroxylamine-O-sulfonic acid forms with aldehydes and ketones (e.g. cyclohexanone [22]) diaziridines, which can easily be oxidized to the more stable diazirines. 3,3-Pentamethylendiaziridin durch Reaktion of Cyclohexanon mit HOSA
