Methyl benzoate is an organic compound. It is an ester with the chemical formula C 6 H 5 COOCH 3, sometimes abbreviated as PhCO 2 Me, where Ph and Me are phenyl and methyl, respectively. Its structure is C 6 H 5 −C(=O)−O−CH 3. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents.
In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.
Methyl 4-bromophenylacetate is made from 4-bromophenylacetic acid by Fischer esterification, refluxing it with methanol acidified with sulfuric acid. [3] An ethyl ester can be made in an analogous way using ethanol instead of methanol. [4] A hydrazone derivative, 2-(4-bromophenyl)acetohydrazide, is made by refluxing the methyl ester with ...
acid + base → salt + water. For example: HCl + NaOH → NaCl + H 2 O. Acidimetry is the specialized analytical use of acid-base titration to determine the concentration of a basic (alkaline) substance using standard acid. This can be used for weak bases and strong bases. [8] An example of an acidimetric titration involving a strong base is as ...
Methyl bromoacetate is an alkylating agent. It has been used to alkylate phenol and amino groups. [4] [5] Moreover, it can be used to make vitamins and pharmaceutical drugs. It is commonly used as a reagent in chemical modification of histidine. [2] In addition, methyl bromoacetate also use in synthesize of coumarins and cis-cyclopropane.
Ethyl bromoacetate is listed by the World Health Organization as a riot control agent, and was first employed for that purpose by French police in 1912. [4] The French army used rifle grenades 'grenades lacrymogènes' [5] filled with this gas against the Germans beginning in August 1914, but the weapons were largely ineffective, even though ethyl bromoacetate is twice as toxic as chlorine.
This reagent can be used, e.g. in the reaction with carbon dioxide to prepare benzoic acid. [4] Other methods involve palladium-catalyzed coupling reactions , such as the Suzuki reaction . Bromobenzene is used as a precursor in the manufacture of phencyclidine .
Benzyl bromide is used in organic synthesis for the introduction of the benzyl groups when the less expensive benzyl chloride is insufficiently reactive. [6] [7] Benzylations are often achieved in the presence of catalytic amounts of sodium iodide, which generates the more reactive benzyl iodide in situ. [3]
