The molecular formula C 5 H 13 N (molar mass: 87.166 g/mol, exact mass: 87.10480 u) may refer to: 1-Aminopentane; 3-Aminopentane; N,N-Diethylmethylamine; N ...
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(NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
When R 3 is OH, the imine is called an oxime, and when R 3 is NH 2 the imine is called a hydrazone. A primary imine in which C is attached to both a hydrocarbyl and a H (derived from an aldehyde) is called a primary aldimine; a secondary imine with such groups is called a secondary aldimine. [10]
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.
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 ...
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.
Typical Lewis bases are conventional amines such as ammonia and alkyl amines. Other common Lewis bases include pyridine and its derivatives. They are nucleophilic in nature Some of the main classes of Lewis bases are: amines of the formula NH 3−x R x where R = alkyl or aryl. Related to these are pyridine and its derivatives.
