2-(4-METHYLPHENYL)ETHANOL

2-(4-Methylphenyl)ethanol (CAS 699-02-5), also known as p-Methylphenethyl alcohol or 4-Methylphenethyl alcohol, is a high-purity para-substituted phenethyl alcohol intermediate widely used in pharmaceutical synthesis, organic chemistry research, fragrance chemistry, and fine chemical manufacturing. This compound features a methyl group at the para-position of the phenethyl alcohol structure, making it a versatile building block for the development of complex organic molecules, active pharmaceutical ingredients (APIs), and specialty fragrance compounds. As a key intermediate in ether synthesis, esterification, and functional group transformations, it exhibits excellent reactivity in Williamson ether synthesis, oxidation reactions, and nucleophilic substitution pathways. Our product is manufactured under strict quality control standards, ensuring a purity of ≥98%, making it ideal for pharmaceutical manufacturing, medicinal chemistry research, fragrance formulation, and scale-up production. This compound is particularly valuable in the synthesis of pharmaceuticals containing para-substituted aromatic structures, perfume intermediates, and agrochemical precursors. As a reliable benzene derivative intermediate, it serves as an important precursor for constructing methyl-protected phenolic scaffolds in drug discovery and flavor-fragrance development programs.
