Description

1,3-Propanediyl Bismethanethiosulfonate is a specialized organic sulfur compound with a unique bis-thiosulfonate structure, serving as a critical cross-linking and modifying agent. Its value lies in its ability to form stable disulfide bonds or act as a sulfhydryl-reactive reagent, enabling precise chemical modifications in advanced materials and bioconjugation. This product is essential for researchers and manufacturers in the pharmaceutical, polymer science, and specialty chemical industries who require high-purity intermediates for synthesis and material development.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and as a bioconjugation reagent for antibody-drug conjugates (ADCs) or protein modification.
• Polymer Cross-Linking Agent: Imparts specific mechanical and chemical resistance properties to specialty polymers and elastomers through disulfide bridge formation.
• Biochemical Research: Acts as a sulfhydryl-reactive probe or cross-linker in proteomics and molecular biology studies for analyzing protein structure and interactions.
• Material Science: Employed in the surface functionalization of nanoparticles and the development of stimuli-responsive or self-healing materials.
• Chemical Synthesis: Serves as a versatile building block for synthesizing more complex sulfur-containing heterocycles and functional molecules.

Quality Control

Our 1,3-Propanediyl Bismethanethiosulfonate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and moisture, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
