Description

2-(3,5-Dichlorophenyl)Ethanethiol is a specialized organosulfur compound featuring a dichlorinated aromatic ring, serving as a versatile building block in advanced organic synthesis. Its value lies in its unique thiol functionality, which allows for efficient conjugation and the introduction of sulfur-containing moieties into complex molecular architectures. This intermediate is primarily needed by R&D chemists and process development scientists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in areas requiring thioether or disulfide linkages.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides that leverage its aromatic chlorine and thiol reactivity.
• Ligand and Catalyst Preparation: Serves as a precursor for creating specialized ligands used in metal-catalyzed cross-coupling reactions.
• Polymer Modification: Employed to introduce thiol groups into polymer backbones or as a chain-transfer agent in controlled radical polymerizations.
• Material Science Research: Utilized in the development of self-assembled monolayers (SAMs) and surface functionalization on gold and other substrates.
• Chemical Biology Probes: Acts as a starting material for synthesizing bioconjugation reagents and probes that target specific biological pathways.

Quality Control

Our production of 2-(3,5-Dichlorophenyl)Ethanethiol adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity for research and development applications. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C). Keep the container tightly sealed in a cool, dry, and well-ventilated place, away from sources of ignition and incompatible materials such as strong oxidizing agents.
