Methylamine, also known as methanamine, is an organic compound with a formula of CH 3 NH 2. This colorless gas is a derivative of ammonia , but with one hydrogen atom being replaced by a methyl group .
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.
It is an ammonium salt composed of methylamine and hydrogen chloride. One potential application for the methylammonium halides is in the production of perovskite solar cells. [3] [4] The methyl group and other hydrogen atoms are bonded covalently to the nitrogen, with the chloride bonded ionically.
Dimethylamine is a weak base and the pKa of the ammonium CH 3-NH + 2-CH 3 is 10.73, a value above methylamine (10.64) and trimethylamine (9.79). Dimethylamine reacts with acids to form salts, such as dimethylamine hydrochloride, an odorless white solid with a melting point of 171.5 °C.
A Lewis base is often a Brønsted–Lowry base as it can donate a pair of electrons to H +; [11] the proton is a Lewis acid as it can accept a pair of electrons. The conjugate base of a Brønsted–Lowry acid is also a Lewis base as loss of H + from the acid leaves those electrons which were used for the A—H bond as a lone pair on the ...
The cation in this salt is called benzylammonium and is a moiety found in pharmaceuticals such as the anthelmintic agent bephenium hydroxynaphthoate, used in treating ascariasis. [ 26 ] Other derivatives of benzylamine and its salts have been shown to have anti-emetic properties, including those with the N -(3,4,5-trimethoxybenzoyl)benzylamine ...
The Schiff base is an electrophile which reacts in a second step in an electrophilic addition with an enol formed from a carbonyl compound containing an acidic alpha-proton. The Mannich reaction is a condensation reaction. [4]: 140 In the Mannich reaction, primary or secondary amines or ammonia react with formaldehyde to form a Schiff base ...
It is the salt formed by the neutralization of methylamine with nitric acid. This substance is also known as methylamine nitrate and monomethylamine nitrate, not to be confused with methyl nitramine or monomethyl nitramine. Methylammonium nitrate was first used as an explosive ingredient by the Germans during World War II. [1]
