Description

4-Mercaptohydrocinnamic Acid is a versatile sulfur-containing aromatic carboxylic acid derivative, valued for its unique thiol and carboxylic acid functional groups. This compound is a critical building block in organic synthesis, particularly for creating complex molecules in pharmaceutical and material science research. Key industries that utilize this intermediate include pharmaceutical development, agrochemical synthesis, and polymer chemistry for specialty applications.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those targeting neurological and cardiovascular diseases.
• Peptide Synthesis: Used for introducing thiol functional groups into peptides and proteins for conjugation, labeling, and structural studies.
• Polymer Modification: Acts as a chain transfer agent or functional monomer to impart specific properties like adhesion or reactivity to polymers and resins.
• Ligand Synthesis: Serves as a building block for creating chelating agents and ligands used in catalysis and metal ion extraction.
• Bioconjugation Chemistry: Employed in the development of linkers for antibody-drug conjugates (ADCs) and other bioconjugates.
• Agrochemical Research: An intermediate in the development of novel herbicides, fungicides, and plant growth regulators.
• Material Science: Used in surface functionalization and the creation of self-assembled monolayers (SAMs) on gold and other surfaces.

Quality Control

Our 4-Mercaptohydrocinnamic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all specifications 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 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.
