Product Description:

Methyl 4-methylbenzoate is an organic compound with the molecular formula C9H10O2. It is a clear, colorless to pale yellow liquid with a characteristic aromatic odor. Structurally, it is the methyl ester of p-toluic acid (4-methylbenzoic acid). This compound is primarily used as a versatile intermediate in organic synthesis and as a starting material for the production of various fine chemicals. It serves as a key building block in the synthesis of pharmaceuticals, agrochemicals, and fragrances. Its ester group can be hydrolyzed to the corresponding carboxylic acid or transesterified, and the aromatic ring can undergo various electrophilic substitution reactions. Methyl 4-methylbenzoate is also employed as a solvent and a flavor/fragrance ingredient due to its pleasant odor. It is considered a relatively stable compound but should be handled with standard laboratory precautions, including adequate ventilation and the use of personal protective equipment.
