Description

Ammonium 2-Mercaptopropionate is the ammonium salt of 2-mercaptopropionic acid, a versatile sulfur-containing organic compound. This chemical is valued for its role as a precursor and intermediate in the synthesis of more complex molecules, particularly in the pharmaceutical and specialty chemical sectors. Key industries that utilize this material include pharmaceutical manufacturing, where it serves in the synthesis of active pharmaceutical ingredients (APIs), and agrochemical production for creating novel crop protection agents.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of various active pharmaceutical ingredients (APIs), particularly those requiring a thiol functional group.
• Agrochemical Synthesis: Used as a precursor in the manufacture of herbicides, fungicides, and other crop protection chemicals.
• Polymer Modification: Acts as a chain transfer agent or modifier in radical polymerization processes to control molecular weight and introduce functional groups.
• Biochemical Research: Employed in proteomics and biochemistry for protein labeling, cross-linking, and as a reducing agent in specific reaction systems.
• Cosmetic Ingredient Intermediate: Used in the synthesis of certain hair care and skin care actives, such as derivatives for permanent wave solutions or antioxidants.
• Chemical Synthesis: A versatile reagent for introducing the 2-mercaptopropionate moiety into target molecules across organic and medicinal chemistry.

Quality Control

Our Ammonium 2-Mercaptopropionate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting results for assay, related substances, residual solvents, and other critical parameters are provided with every shipment. We support compliance with cGMP and ICH Q7 guidelines for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; for long-term storage, consider keeping under an inert atmosphere (nitrogen or argon) in a desiccated environment. Keep away from strong oxidizing agents and acids.
