Description

Mercaptoethylammonium Bromide is a versatile organosulfur compound featuring both a thiol (mercapto) group and a quaternary ammonium moiety. This dual functionality makes it a valuable intermediate and additive in advanced chemical synthesis and material science. It is particularly sought after by manufacturers in the pharmaceutical, polymer, and specialty chemical industries for its role as a precursor, catalyst, or surface-modifying agent.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring thiol or ammonium functionalities.
• Polymer Modification: Used as a chain transfer agent or cross-linking agent in the production of specialty polymers and resins to alter physical properties.
• Surface Active Agent: Functions as a cationic surfactant or conditioner in formulations for personal care and industrial cleaning products.
• Bioconjugation Chemistry: Serves as a linker or reagent for attaching molecules to surfaces or biomolecules via its reactive thiol group.
• Corrosion Inhibitor: Applied in functional fluids and coatings where its molecular structure helps protect metal surfaces.
• Research & Development: A valuable reagent in organic synthesis and material science research for exploring new chemical entities.

Quality Control

Our Mercaptoethylammonium Bromide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting purity, physical characteristics, and safety data are provided with every shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air.
