Description

2-Hydroxyethyl Disulfide Mono-Tosylate is a specialized organosulfur compound featuring a disulfide linkage and a tosylate leaving group. This unique bifunctional structure makes it a valuable intermediate for the synthesis of complex molecules, particularly in the development of pharmaceuticals and advanced materials. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce specific sulfur-based functionalities or create novel molecular architectures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those containing disulfide bonds or requiring controlled functionalization.
• Bioconjugation Reagent: Used for the modification of peptides, proteins, and other biomolecules, enabling the creation of stable linkages or the attachment of payloads.
• Polymer Chemistry: Serves as a monomer or cross-linking agent in the production of specialty polymers with tailored properties, such as self-healing materials or responsive gels.
• Chemical Synthesis: Acts as a versatile synthon for introducing the 2-hydroxyethyl disulfide moiety into target molecules in organic synthesis.
• Agrochemical Research: Employed in the development of novel herbicides, fungicides, or plant growth regulators that utilize sulfur chemistry.
• Material Science: Used in surface modification and the creation of functional coatings or thin films.

Quality Control

Our 2-Hydroxyethyl Disulfide Mono-Tosylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to exclude moisture. Keep away from incompatible materials such as strong bases and reducing agents.
