Methyl benzoate is formed by the condensation of methanol and benzoic acid, in presence of a strong acid. [1] [2] Methyl benzoate reacts at both the ring and the ester, depending on the substrate. Electrophiles attack the ring, illustrated by acid-catalysed nitration with nitric acid to give methyl 3-nitrobenzoate.
3-Nitrobenzoic acid is an organic compound with the formula C 6 H 4 (NO 2)CO 2 H. It is an aromatic compound and under standard conditions, it is an off-white solid. The two substituents are in a meta position with respect to each other, giving the alternative name of m-nitrobenzoic acid.
3-Nitrobenzoic acid is a precursor to 3-aminobenzoic acid, which in turn is used to prepare some dyes. It can be prepared by nitration of benzoic acid. It also can be prepared by treating benzaldehyde under nitration conditions, a process that initially converts the aldehyde to the acid.
3,5-dinitrobenzoic acid-2-propylester (mp.: 123 °C [4]). Compared to 4-nitrobenzoic acid , another acid that is used similarly, derivates of 3,5-dinitrobenzoic acid have higher melting points, so that it is preferred when the 4-nitrobenzoic acid derivate has a melting point too low to be accurately identified.
3-Nitrobenzaldehyde is an organic compound with the formula O 2 NC 6 H 4 CHO. It is one of three isomers of nitrobenzaldehyde. It contains a nitro group meta-substituted to the aldehyde. 3-Nitrobenzaldehyde is the primary product obtained via the mono-nitration of benzaldehyde with nitric acid. [3] C 6 H 5 CHO + HNO 3 → O 2 NC 6 H 4 CHO + H 2 O
Methyl 2-methyl-3-nitrobenzoate is brominated using N-bromosuccinimide and the product is treated with 3-amino-piperidine-2,6-dione, a cyclic derivative of glutamine to form a lactam. Catalytic hydrogenation then gives lenalidomide.
Bifenox is not currently used in the United States [13] although in 1981 it had been subject to a full regulatory review, under the then-new "Registration Standard" process. [10] Within the European Union, a 2-tiered approach is used for the approval and authorisation of pesticides. Firstly, before a formulated product can be developed for ...
CH 3 OH + HNO 3 → CH 3 NO 3 + H 2 O. A newer method uses methyl iodide and silver nitrate: [4] CH 3 I + AgNO 3 → CH 3 NO 3 + AgI. Methyl nitrate can be produced on a laboratory or industrial scale either through the distillation of a mixture of methanol and nitric acid, or by the nitration of methanol by a mixture of sulfuric and nitric acids.
