Description

3-Aminothiophenol is a versatile aromatic compound featuring both an amine and a thiol functional group, making it a valuable bifunctional building block in organic synthesis. Its primary commercial value lies in its role as a key intermediate for the production of pharmaceuticals, agrochemicals, and advanced materials. This compound is particularly essential for researchers and manufacturers in the pharmaceutical and fine chemical industries who require a reliable, high-purity precursor for heterocyclic synthesis and ligand preparation.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of benzothiazole and other sulfur- and nitrogen-containing heterocycles with biological activity.
• Agrochemical Synthesis: Used in the manufacture of fungicides, herbicides, and other crop protection agents.
• Dye and Pigment Production: Serves as a building block for sulfur-based dyes and organic pigments.
• Polymer and Material Science: Acts as a monomer or cross-linking agent for specialty polymers and as a ligand for metal complex catalysts.
• Chemical Research & Development: Employed in academic and industrial R&D for novel compound libraries and methodological studies.

Quality Control

Our 3-Aminothiophenol is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, GC, and NMR to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with every shipment to support your quality assurance protocols.

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) for long-term preservation. Keep away from strong oxidizing agents.
