In the intricate landscape of specialty chemicals, understanding the properties and applications of each compound is crucial for successful product development and manufacturing. 3-Mercaptopropionic Acid (3-MPA), identified by CAS 107-96-0, is a prime example of such a vital chemical intermediate. Possessing a unique combination of a thiol group (-SH) and a carboxylic acid group (-COOH), 3-MPA exhibits remarkable reactivity and versatility. As a leading manufacturer and supplier from China, we are dedicated to providing a detailed overview of this important compound, highlighting its chemical characteristics and diverse applications. If you are looking to buy 3-Mercaptopropionic Acid, this information will be invaluable.

Key Chemical Properties of 3-MPA

3-Mercaptopropionic Acid is typically described as a colorless transparent liquid, with a distinct, strong odor characteristic of thiols. Its molecular formula is C3H6O2S, and it has a molecular weight of 106.14. A critical physical property for handling and storage is its melting point, which is around 16.8°C. This means that at typical room temperatures, it remains a liquid, simplifying its use in many industrial processes. However, it can solidify below this temperature, requiring careful storage conditions. The assay, a measure of purity, is consistently high, with a typical specification of 99.0% min. This high purity is essential for its demanding applications, such as in pharmaceutical synthesis and as a chain transfer agent in polymerizations.

Diverse Applications Across Industries

The dual functionality of 3-MPA makes it a sought-after intermediate in several key industries:

  • Pharmaceutical Intermediate: It serves as a crucial building block for synthesizing various pharmaceutical compounds and APIs, leveraging its reactive functional groups.
  • Chain Transfer Agent: In polymerization processes, particularly for acrylic monomers and polycarboxylate superplasticizers, 3-MPA helps control molecular weight and polymer architecture.
  • PVC Stabilizers: It is a key raw material in the production of tin-based and other heat stabilizers for PVC, enhancing the material's thermal resistance.
  • Catalyst: Its acidic nature allows it to act as a catalyst in certain organic synthesis reactions.
  • Concrete Admixtures: It can be incorporated into concrete formulations to modify properties such as workability and setting time.
