Description

Benzenethiol, 2-Amino-3-Ethyl- CAS NO 139331-76-3 is a specialized aromatic thiol derivative characterized by the presence of both amino and ethyl functional groups on the benzene ring. This unique molecular structure makes it a valuable intermediate for synthesizing complex molecules in advanced research and industrial applications. It is primarily sought after by pharmaceutical R&D teams and fine chemical manufacturers for constructing heterocyclic compounds and as a building block for ligands and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting neurological and oncological pathways.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides due to its reactive thiol and amino groups.
• Material Science: Serves as a monomer or functionalizing agent in the production of specialty polymers and conductive materials.
• Chemical Research: Employed as a versatile building block in organic synthesis for creating complex sulfur- and nitrogen-containing compounds.
• Catalyst Ligand Preparation: Utilized to synthesize chelating ligands for metal catalysts used in asymmetric synthesis.
• Flavor & Fragrance Industry: Acts as an intermediate for producing certain sulfur-containing aroma chemicals.

Quality Control

Our production of Benzenethiol, 2-Amino-3-Ethyl- adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and GC-MS for identity confirmation, to ensure it meets exacting customer specifications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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.
