Benzenesulfonic acid, 4-methyl-, methyl ester

Description:

4-Methylbenzenesulfonic acid methyl ester, also known as methyl 4-methylbenzenesulfonate, is an organic compound characterized by its sulfonate functional group attached to a methyl-substituted benzene ring. This compound typically appears as a colorless to pale yellow liquid with a sweet, aromatic odor. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic aromatic structure. The presence of the sulfonate group imparts polar characteristics, making it a useful intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It is also utilized in various applications, including as a reagent in chemical reactions and as a surfactant. Safety data indicates that it should be handled with care, as it may cause irritation to the skin and eyes. Proper storage in a cool, dry place away from incompatible substances is recommended to maintain its stability and efficacy.

Methyl p-toluenesulfonate

CAS: 80-48-8

Methyl p-toluenesulfonate is an oxidation catalyst that is used in the preparation of samples for structural analysis, such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS). It may also be used to synthesize cationic polymers. Methyl p-toluenesulfonate has been shown to have antimicrobial properties against gram positive bacteria, which are caused by the hydroxyl group on the methyl group. This compound can also react with halides, such as chloride and bromide, and lc-ms/ms methods.
