Anisic acid or methoxybenzoic acid is an organic compound which is a carboxylic acid. It exists in three forms, depending on arene substitution patterns: p-Anisic acid (4-methoxybenzoic acid) m-Anisic acid (3-methoxybenzoic acid) o-Anisic acid (2-methoxybenzoic acid)
p-Anisic acid, also known as 4-methoxybenzoic acid or draconic acid, is one of the isomers of anisic acid. The term "anisic acid" often refers to this form specifically. [ 1 ] It is a white crystalline solid which is insoluble in water, highly soluble in alcohols, and soluble in ether and ethyl acetate .
The molecular formula C 8 H 8 O 3 (molar mass: 152.15 g/mol) may refer to: Anisic acids. o-Anisic acid (2-methoxybenzoic acid) m-Anisic acid (3-methoxybenzoic acid) p-Anisic acid (4-methoxybenzoic acid) 3,4-Dihydroxyphenylacetaldehyde; 2-Hydroxy-4-methoxybenzaldehyde; 2-Hydroxy-5-methoxybenzaldehyde; Hydroxyphenylacetic acid. 2 ...
Vanillic acid (4-hydroxy-3-methoxybenzoic acid) is a dihydroxybenzoic acid derivative used as a flavoring agent. It is an oxidized form of vanillin . It is also an intermediate in the production of vanillin from ferulic acid .
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.
It is also prepared commercially by ketonization of benzoic acid and propionic acid over calcium acetate and alumina at 450–550 °C: [1] C 6 H 5 CO 2 H + CH 3 CH 2 CO 2 H → C 6 H 5 C(O)CH 2 CH 3 + CO 2 + H 2 O. Ludwig Claisen discovered that α-methoxystyrene forms this compound when heated for an hour at 300 °C (65% yield). [2] [3]
o-Anisic acid is an organic compound with the formula CH 3 OC 6 H 4 CO 2 H. A colorless solid, it is one of the isomers of anisic acid . The compound has been well studied with respect to intramolecular hydrogen bonding [ 2 ] and as a substrate for various catalystic reactions.
Benzoyl chloride is produced from benzotrichloride using either water or benzoic acid: [2] C 6 H 5 CCl 3 + H 2 O → C 6 H 5 COCl + 2 HCl C 6 H 5 CCl 3 + C 6 H 5 CO 2 H → 2 C 6 H 5 COCl + HCl. As with other acyl chlorides, it can be generated from the parent acid and standard chlorinating agents such as phosphorus pentachloride, thionyl ...
