Description

3,5-Dihydroxyphenylacetic Acid is a valuable phenolic acid derivative characterized by its two hydroxyl groups in the meta position relative to the acetic acid side chain. This specific substitution pattern makes it a versatile intermediate and building block in organic synthesis, particularly for the development of complex molecules with targeted biological activity. It is primarily sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical sectors for applications ranging from drug discovery to material science.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of novel drug candidates, including potential antioxidants, enzyme inhibitors, and receptor ligands.
• Agrochemical Research: Used in the development of new plant growth regulators, herbicides, or fungicides due to its phenolic structure.
• Biochemical Research: Acts as a standard, metabolite analog, or precursor in studies related to tyrosine metabolism and phenolic acid pathways.
• Fine Chemical Synthesis: Employed as a building block for creating complex organic compounds, dyes, and specialty polymers.
• Cosmetic Ingredient Development: Investigated for use in skincare formulations for its potential antioxidant properties.

Quality Control

Our 3,5-Dihydroxyphenylacetic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profile, and physical characteristics. Our quality commitment ensures the material is suitable for demanding research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle under an inert atmosphere for long-term storage of bulk quantities and to minimize headspace in opened containers.
