Description

1,2-Ethanedithiol CAS NO 540-63-6 is a versatile organic sulfur compound characterized by two thiol (-SH) groups on adjacent carbon atoms. This structure makes it a valuable building block and reagent in organic synthesis, particularly for the formation of dithioacetals and as a ligand in metal coordination chemistry. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and polymer industries who require a reliable source of high-purity dithiols for complex chemical transformations.

Application

• Pharmaceutical Intermediate: Used in the synthesis of complex molecules, including potential drug candidates and active pharmaceutical ingredients (APIs).
• Polymer Chemistry: Serves as a chain transfer agent, cross-linking agent, or monomer in the production of specialty polymers and resins.
• Ligand in Catalysis: Acts as a chelating ligand for various transition metals, forming complexes used in catalytic processes.
• Organic Synthesis Reagent: Key reagent for the protection of carbonyl groups via dithioacetal formation and in various thiol-ene click chemistry reactions.
• Agrochemical Synthesis: Employed in the manufacture of certain pesticides and herbicides where the dithiol moiety is integral to the molecule's activity.
• Analytical Chemistry: Used as a derivatization agent for the detection and analysis of specific functional groups.

Quality Control

Our 1,2-Ethanedithiol is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and titration methods, to ensure high purity and consistency. Certificates of Analysis (COA) detailing specific batch results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep container tightly sealed when not in use to prevent evaporation and oxidation.
