The landscape of drug discovery is continuously evolving, driven by the need for novel therapeutics with improved efficacy and safety profiles. Central to this progress is the innovative use of specialty chemical building blocks that enable the synthesis of complex molecular architectures. Among these, thienyl butyric acid derivatives have garnered significant attention in medicinal chemistry due to the unique properties conferred by the thiophene ring and the versatile butyric acid chain.

(S)-3-Amino-4-(3-thienyl)-butyric acid HCl (CAS: 270262-99-2) exemplifies such a valuable compound. This chiral molecule, characterized by its amino group, a thienyl substituent, and a carboxylic acid function (in its salt form), serves as a crucial intermediate in the synthesis of a wide range of biologically active compounds. Researchers often look to buy such molecules to incorporate specific pharmacophores into their drug candidates, aiming to enhance target binding, improve metabolic stability, or modulate pharmacokinetic properties. The availability of this specific compound from reliable suppliers is key for chemists engaged in lead optimization.

The synthesis of these thienyl butyric acid derivatives typically involves sophisticated organic chemistry techniques to ensure the correct stereochemistry and high purity required for pharmaceutical applications. As a supplier of such advanced intermediates, our role is to provide researchers with the tools they need to accelerate their discovery efforts. By offering high-quality products like the hydrochloride salt of this important amino acid, we empower medicinal chemists to explore new chemical spaces and develop innovative treatments for unmet medical needs. Understanding the synthesis pathways and the applications of these derivatives is fundamental for anyone looking to purchase or utilize them effectively in their R&D pipeline.
