1-Ethynyl-4-methoxy-2-methylbenzene, also known by its CAS number 74331-69-4, is an organic compound characterized by its aromatic structure, which includes a benzene ring substituted with an ethynyl group, a methoxy group, and a methyl group. The presence of the ethynyl group introduces a triple bond, contributing to the compound's reactivity and potential applications in organic synthesis. The methoxy group, which is an ether functional group, can influence the compound's solubility and polarity, while the methyl group adds to the overall hydrophobic character. This compound is typically a colorless to pale yellow liquid or solid, depending on its purity and specific conditions. It is used in various chemical reactions, particularly in the synthesis of more complex organic molecules. Additionally, its unique structure may impart specific properties such as fluorescence or enhanced stability under certain conditions, making it of interest in materials science and organic chemistry research. Safety data should be consulted for handling and storage, as with all chemical substances.

1-Ethynyl-4-methoxy-2-methylbenzene (EMMB) is a chemical compound that has been shown to yield two different types of carbonaceous materials. The first type of material is graphitic carbon, which is a form of carbon with a very high surface area and an ability to adsorb many different types of molecules. The second type of material is copper coordination polymers. EMMB can be used as an additive to plastics or other materials in order to protect them from the effects of ultraviolet radiation, such as oxidation and photodegradation. EMMB also has the ability to absorb nitrogen dioxide (NO2) from the atmosphere, making it useful for environmental clean up projects. It can also be used in coordination with azide or glycidyl groups for use in explosives. 
In addition, EMMB can be used as an intermediate for the synthesis of triazolyl and triazole derivatives that are important for their electronic properties and molecular
