Boc-(R)-3-amino-4-(3-benzothienyl)-butyric acid, identified by its CAS number 190190-48-8, is a specialized chemical that offers significant advantages for formulators and synthetic chemists alike. This article outlines its value and provides guidance on sourcing this essential compound.

The Strategic Importance of Boc-(R)-3-Amino-4-(3-benzothienyl)-butyric Acid

This compound is a synthetically useful building block primarily due to its unique structural attributes:

• Boc-Protected Amine: The tert-butyloxycarbonyl (Boc) group is a widely used protecting group in organic synthesis. It safeguards the amine functionality during various reaction steps, allowing for precise manipulation of other parts of the molecule. Its facile removal under mild acidic conditions is a key advantage in multi-step syntheses, common in the development of complex drug molecules.
• Chiral Center: The presence of a defined stereocenter, specifically the (R)-configuration, is crucial for creating enantiomerically pure active pharmaceutical ingredients (APIs). Chirality plays a vital role in how drug molecules interact with biological targets, influencing efficacy and reducing potential side effects.
• Benzothienyl Moiety: The benzothiophene ring structure is a common feature in many biologically active compounds. It can enhance lipophilicity, influence binding affinity to target proteins, and contribute to the overall pharmacokinetic profile of a drug candidate.

These combined features make Boc-(R)-3-amino-4-(3-benzothienyl)-butyric acid a valuable precursor for developing a wide range of pharmaceuticals.
