Description

Mercaptoethylammonium Iodide is a versatile organosulfur compound featuring both a thiol (mercapto) and an ammonium functional group. This unique structure makes it a valuable intermediate and reagent in advanced organic synthesis and pharmaceutical development. It is particularly sought after by research institutions and manufacturers in the life sciences and specialty chemical sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those containing sulfur or requiring specific ammonium salt properties.
• Bioconjugation Reagent: Used for modifying proteins, peptides, and other biomolecules via thiol-reactive chemistry for drug delivery systems and diagnostic assays.
• Ligand Synthesis: Serves as a precursor for creating specialized ligands used in catalysis and metal complexation.
• Polymer Modification: Employed to introduce functional thiol groups into polymer chains, altering material properties for adhesives, coatings, or hydrogels.
• Chemical Research: A valuable reagent in academic and industrial R&D for exploring novel synthetic pathways and developing new chemical entities.
• Surface Functionalization: Used to create self-assembled monolayers (SAMs) on gold and other surfaces for sensor development and nanotechnology applications.

Quality Control

Our Mercaptoethylammonium Iodide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR spectroscopy, and tests for residual solvents and heavy metals. A detailed Certificate of Analysis (COA) is provided with every shipment to ensure traceability and compliance with your research or production 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 (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials such as strong oxidizing agents.
