Benzyl (3-bromopropyl)carbamate

3-(3-Methoxyphenyl)propanoic acid (CAS 39945-54-5), also known as m-Methoxyhydrocinnamic acid or 3-Methoxybenzenepropanoic acid, is a high-purity methoxy-substituted aromatic carboxylic acid intermediate widely used in pharmaceutical synthesis, organic chemistry research, fragrance chemistry, and fine chemical manufacturing. This compound features a methoxy group at the meta-position of the phenyl ring linked to a propanoic acid side chain, making it a versatile building block for the development of complex organic molecules and active pharmaceutical ingredients (APIs). As a key intermediate in esterification, amide coupling, and functional group transformations, it exhibits excellent reactivity in Friedel-Crafts acylation, cross-coupling reactions, and derivatization 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 meta-methoxyphenyl scaffolds, anti-inflammatory drug intermediates, fragrance precursors, and specialty chemical precursors. As a reliable benzene derivative intermediate from our product line, it serves as an important precursor for constructing functionalized aromatic carboxylic acid systems in drug discovery and fine chemical development programs.
