Description

2-Mercaptophenylbutyric Acid is a specialized organosulfur compound featuring both a thiol (mercapto) and a carboxylic acid functional group, making it a versatile building block for chemical synthesis. Its unique bifunctional structure allows it to act as a key intermediate in the development of pharmaceuticals, agrochemicals, and advanced materials. This high-purity chemical is essential for research and development chemists, process engineers, and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries seeking to create novel compounds with specific biological or material properties.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs targeting metabolic or inflammatory pathways.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators where the thiol group enables unique modes of action.
• Ligand and Chelating Agent: Serves as a building block for creating custom ligands in catalysis and metal-chelating agents for analytical or therapeutic applications.
• Polymer Modification: Employed to introduce thiol or carboxylic acid functionalities into polymer chains, modifying properties like adhesion, cross-linking, or biocompatibility.
• Bioconjugation Chemistry: Utilized in the development of linkers for antibody-drug conjugates (ADCs) or protein labeling due to its reactive thiol group.
• Research & Development: A valuable tool compound in medicinal chemistry and chemical biology for exploring new synthetic routes and biological targets.

Quality Control

Every batch of 2-Mercaptophenylbutyric Acid is manufactured under strict quality management systems and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, which includes results from advanced techniques such as HPLC, GC, NMR, and titration. Our quality commitment ensures the material meets the stringent requirements for use as a pharmaceutical intermediate and in other critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents, strong bases, and sources of heat.
