Description

3-Mercaptophenylbutyric Acid is a specialized organic compound featuring both a thiol (mercapto) and a carboxylic acid functional group on a phenylbutyric acid backbone. This unique bifunctional structure makes it a valuable building block and intermediate in advanced organic synthesis, particularly for the development of pharmaceuticals and fine chemicals. It is primarily utilized by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and material science sectors for creating novel compounds with targeted properties.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs), especially those requiring thiol or disulfide linkages.
• Ligand Synthesis: Used in the preparation of chelating agents and ligands for catalysis and metal complexation.
• Peptide Mimetics & Conjugation: Serves as a versatile linker or side-chain component in the design of peptide analogs and bioconjugates.
• Polymer Modification: Employed to introduce thiol groups into polymers for cross-linking, functionalization, or creating responsive materials.
• Agrochemical Research: Intermediate in the synthesis of novel herbicides, fungicides, or plant growth regulators.
• Chemical Biology Probes: Useful for creating probes that target biological thiols or for studying redox processes.

Quality Control

Our 3-Mercaptophenylbutyric Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure high purity and consistency, meeting the stringent requirements for research and industrial synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment and are available upon request.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
