N,N-Diethylmethylamine (diethylmethylamine, DEMA) is a tertiary amine with the formula C 5 H 13 N. N,N-Diethylmethylamine is a clear, colorless to pale yellow liquid at room temperature, and is used in various industrial and scientific applications including water desalination as well as analytical and organic chemistry.

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(NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
Imines are related to ketones and aldehydes by replacement of the oxygen with an NR group. When R = H, the compound is a primary imine, when R is hydrocarbyl , the compound is a secondary imine. If this group is not a hydrogen atom, then the compound can sometimes be referred to as a Schiff base . [ 9 ]
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.
Neopentylamine is an organic compound with the molecular formula (CH 3) 3 CCH 2 NH 2. It is a colorless liquid. The molecule is the primary amine derivative of neopentane, (CH 3) 4 C. Like most alkyl amines, it degrades slowly in air. [1]
Compared to amines, amides are very weak bases. While the conjugate acid of an amine has a pK a of about 9.5, the conjugate acid of an amide has a pK a around −0.5. Therefore, compared to amines, amides do not have acid–base properties that are as noticeable in water. This relative lack of basicity is explained by the withdrawing of ...
A carbon–nitrogen bond is a covalent bond between carbon and nitrogen and is one of the most abundant bonds in organic chemistry and biochemistry. [1]Nitrogen has five valence electrons and in simple amines it is trivalent, with the two remaining electrons forming a lone pair.
