3-Methoxyphenylacetic Acid丨CAS 1798-09-0

3-Methoxyphenylacetic acid is a versatile organic intermediate widely used in pharmaceutical and chemical research. It serves as a building block for the synthesis of bioactive compounds, including anti-inflammatory agents, cardiovascular drugs, and central nervous system (CNS) therapeutics. The methoxy-substituted phenyl ring provides electronic and steric properties that are valuable in drug design and medicinal chemistry. Additionally, it is utilized in the preparation of fine chemicals, agrochemicals, and specialty intermediates, where the carboxylic acid group enables further derivatization into esters, amides, and other functional compounds. Its chemical structure also makes it suitable for incorporation into dyes, polymers, and other specialty materials.

3-Methoxyphenylacetic acid offers multiple advantages due to its functional group diversity and chemical stability. The combination of a methoxy-substituted aromatic ring and carboxylic acid provides reactive sites for selective chemical transformations, allowing high-yield synthesis of derivatives and analogs. It is soluble in organic solvents, stable under standard laboratory conditions, and compatible with common reagents, making it convenient for both small-scale research and industrial synthesis. The methoxy group can enhance the lipophilicity and electronic properties of derivatives, improving their pharmacokinetic and bioactive profiles. Its versatility in derivatization enables efficient development of novel compounds for pharmaceuticals, agrochemicals, and materials science.
