2-Methoxybenzaldehyde is an organic compound with the formula CH 3 OC 6 H 4 CHO. It is also commonly referred to as o-anisaldehyde. As a methylated version of salicylaldehyde, the molecule consists of a benzene ring with adjacent formyl and a methoxy groups. It is a colorless solid with a pleasant aroma.
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.
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)
It is an isomer of p-toluic acid and m-toluic acid. When purified and recrystallized, o-toluic acid forms needle-shaped crystals. o-Toluic acid was first noticed by Sir William Ramsay, credited discoverer of the noble gases and winner of the 1904 Nobel Prize in Chemistry. o-Toluic acid is prepared by oxidation of o-xylene with nitric acid.

The FT-IR spectra were recorded using a Nicolet 170SX or a JASCO FT/IR-410 spectrometer. For spectra recorded in the Nicolet spectrometer, the data were stored at intervals of 0.5 cm −1 in the 4,000 – 2,000 cm −1 region and of 0.25 cm −1 in the 2,000 – 400 cm −1 region and the spectral resolution was 0.25 cm −1.
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)
Spectrochemistry is the application of spectroscopy in several fields of chemistry. It includes analysis of spectra in chemical terms, and use of spectra to derive the structure of chemical compounds, and also to qualitatively and quantitively analyze their presence in the sample.
