For chemical engineers, R&D scientists, and procurement managers, a deep understanding of a compound's chemical properties is foundational to its successful application. 3-Amino-3-phenylpropionic Acid (CAS 614-19-7), a compound often sought for its role as a versatile intermediate, possesses a unique set of characteristics stemming from its molecular structure. This white crystalline powder, with the molecular formula C9H11NO2, offers a fascinating blend of reactivity and stability, making it valuable across various chemical disciplines. Knowing these properties helps buyers make informed decisions when purchasing this key chemical.

Molecular Structure and Reactivity Profile

At its core, 3-Amino-3-phenylpropionic Acid is a beta-amino acid derivative. This means the amino group (-NH2) is attached to the beta-carbon atom, which is two carbons away from the carboxyl group (-COOH). The presence of a phenyl ring (C6H5) attached to the same beta-carbon atom as the amino group introduces aromaticity and steric bulk. This unique arrangement results in several key reactive features:

  • Amphoteric Nature: The molecule contains both an acidic carboxyl group and a basic amino group. This amphoteric nature allows it to react with both acids and bases. The carboxyl group can donate a proton, forming a carboxylate anion, while the amino group can accept a proton, forming an ammonium cation. This property is crucial for its behavior in solution and its ability to act as a buffer or participate in acid-base catalyzed reactions.
  • Peptide Bond Formation: Like other amino acids, it can participate in reactions to form amide bonds, commonly known as peptide bonds, when activated appropriately. This is fundamental to its use in synthesizing peptide-like structures or modified amino acid chains for pharmaceutical and material science applications.
  • Chirality: The beta-carbon atom, bonded to the amino group, carboxyl group, phenyl ring, and a hydrogen atom, is a chiral center (unless the molecule is a racemic mixture, like DL-β-Phenylalanine). This chirality is significant in pharmaceutical applications, where enantiomeric purity can drastically affect a drug's biological activity and safety profile. When you buy this compound, understanding whether it is a racemic mixture or a specific enantiomer is crucial for certain synthesis pathways.

Physical Properties: Handling and Storage

The physical properties of 3-Amino-3-phenylpropionic Acid also dictate its handling and storage requirements. Typically appearing as a white to off-white crystalline powder, it has a relatively high melting point, often around 222°C with decomposition, indicating good thermal stability under normal conditions. Its solubility characteristics are also important; it is often described as soluble in hot water and alcohols but less so in cold water or ethers. This solubility profile can influence reaction solvent choices and purification methods. Manufacturers typically recommend storing it in a cool, dark place, under an inert atmosphere if possible, to maintain its integrity and prevent degradation over time.

Applications Driven by Chemical Properties

These chemical properties directly translate into its utility. As an intermediate, its ability to undergo specific reactions allows chemists to build more complex molecules. For instance, its role in synthesizing platelet aggregation inhibitors or GnRH receptor antagonists relies on precise chemical transformations involving its amino and carboxyl groups. In material science, its potential for polymerization and modification leverages its reactive functional groups to create specialized polymers and biomaterials with desired properties.

For any buyer, understanding these chemical properties allows for better communication with suppliers and a more informed selection process.
