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atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
Amino acid. Structure of a typical L -alpha-amino acid in the "neutral" form. Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. [2]
Ethylamine, also known as ethanamine, is an organic compound with the formula CH 3 CH 2 NH 2. This colourless gas has a strong ammonia -like odor. It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines.
Asparagine (zwitterionic form), an amino acid with a side chain (highlighted) containing an amide group. In organic chemistry, an amide, [1][2][3] also known as an organic amide or a carboxamide, is a compound with the general formula R−C (=O)−NR′R″, where R, R', and R″ represent any group, typically organyl groups or hydrogen atoms ...
In chemistry, the amino radical, ·NH2, also known as the aminyl or azanyl, is the neutral form of the amide ion (NH− 2). Aminyl radicals are highly reactive and consequently short-lived, like most radicals; however, they form an important part of nitrogen chemistry. In sufficiently high concentration, amino radicals dimerise to form hydrazine.
Amidine. The skeletal formula of acetamidine (acetimidamide). Amidines are organic compounds with the functional group RC (NR)NR 2, where the R groups can be the same or different. They are the imine derivatives of amides (RC (O)NR 2). The simplest amidine is formamidine, HC (=NH)NH 2. Examples of amidines include:
Cyclohexylamine is used as an intermediate in synthesis of other organic compounds. It is the precursor to sulfenamide -based reagents used as accelerators for vulcanization. The amine itself is an effective corrosion inhibitor. It has been used as a flushing aid in the printing ink industry. [5]
Amine value. In organic chemistry, amine value is a measure of the nitrogen content of an organic molecule. [1] Specifically, it is usually used to measure the amine content of amine functional compounds. [2] It may be defined as the number of milligrams of potassium hydroxide (KOH) equivalent to one gram of epoxy hardener resin.
