Description

3-Chloro-4-Sulfanylbenzoic Acid is a versatile aromatic compound featuring both a carboxylic acid and a sulfanyl (thiol) functional group on a chlorinated benzene ring. This unique structure makes it a valuable building block for synthesizing more complex molecules in advanced chemical research and development. It is primarily sought after by professionals in the pharmaceutical and agrochemical industries for creating novel active ingredients and intermediates.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a thiol or disulfide linkage for bioactivity.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and plant growth regulators.
• Ligand and Catalyst Development: The thiol and carboxylic acid groups make it a useful starting material for creating chelating ligands in coordination chemistry and catalysis.
• Material Science Research: Employed in the development of specialty polymers, functionalized surfaces, and advanced organic materials.
• Chemical Biology Probe: Acts as a building block for synthesizing probes that target biological thiols or for protein conjugation studies.
• Fine Chemical Production: Utilized in custom and contract synthesis for producing high-value, low-volume specialty chemicals.

Quality Control

Our 3-Chloro-4-Sulfanylbenzoic Acid is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
