Description

3-Mercaptopropionamide is a versatile sulfur-containing organic compound featuring both a thiol and an amide functional group. This dual functionality makes it a valuable building block and intermediate in the synthesis of more complex molecules, particularly in pharmaceutical and agrochemical research. It is essential for industries requiring the introduction of a thiol moiety or the construction of heterocyclic compounds. The product is supplied under the CAS registry number 763-35-9.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those containing thioether or disulfide linkages.
• Agrochemical Synthesis: Used in the production of certain herbicides, fungicides, and plant growth regulators.
• Polymer Modification: Acts as a chain transfer agent or cross-linking agent in specialty polymer formulations.
• Bioconjugation Chemistry: Utilized for modifying proteins, peptides, and other biomolecules via its reactive thiol group.
• Organic Synthesis Building Block: Serves as a versatile reagent for constructing thiazoles, thiazolidines, and other sulfur heterocycles.
• Chemical Research & Development: A valuable tool for medicinal chemistry and material science research projects.

Quality Control

Our 3-Mercaptopropionamide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identity confirmation by IR spectroscopy and purity determination by HPLC, to ensure it meets precise specifications. A detailed Certificate of Analysis (COA) documenting purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical applications.

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 properties of being easily oxidized (store under inert atmosphere) and light-sensitive, prolonged exposure to air or light should be avoided. Keep away from strong oxidizing agents.
