Description

2-(Methylamino)Benzenethiol CAS NO 21749-63-3 is a specialized aromatic thiol derivative featuring both a thiol (-SH) and a methylamino (-NHCH₃) functional group. This unique bifunctional structure makes it a valuable intermediate for synthesizing complex molecules in advanced research and industrial chemistry. It is primarily sought after by manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and material science sectors for applications requiring precise sulfur and nitrogen incorporation.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds with sulfur-containing heterocycles or those requiring specific chelating properties.
• Agrochemical Synthesis: Used in the development of novel pesticides, herbicides, and fungicides where the thiol group acts as a reactive site for creating sulfur bridges or metal-binding agents.
• Ligand Precursor in Catalysis: Serves as a starting material for preparing specialized ligands used in transition metal catalysis for organic transformations.
• Polymer Modification: Employed as a chain-transfer agent or functional monomer to introduce thiol groups into polymer backbones, modifying properties like adhesion and cross-linking potential.
• Chemical Research & Development: A versatile reagent in academic and industrial R&D for exploring new synthetic pathways and creating novel chemical entities.
• Material Science: Investigated for use in the creation of self-assembled monolayers (SAMs) on metal surfaces and in the development of advanced organic electronic materials.

Quality Control

Our 2-(Methylamino)Benzenethiol is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurities is provided with every shipment to guarantee traceability and consistency.

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.
