Description

Ethanethioic Acid, S-[2-Amino-3-(2-Methylphenyl)Propyl] Ester (9Ci) is a specialized organic sulfur compound with a defined chiral center, serving as a valuable synthetic intermediate in advanced chemical synthesis. Its molecular architecture, featuring a thioester linkage and a protected amino group adjacent to a methylphenyl moiety, makes it a critical precursor for constructing complex pharmacologically active molecules. This compound is primarily sought by research institutions and pharmaceutical development companies engaged in the creation of novel therapeutic agents and fine chemical libraries.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of potential drug candidates, particularly those targeting neurological or metabolic pathways.
• Peptidomimetic Research: Used in the development of peptide analogs and mimetics due to its amino acid-like backbone with a thioester functional group.
• Chemical Biology Probes: Serves as a precursor for activity-based probes used to study enzyme function and mechanism.
• Asymmetric Synthesis: Employed as a chiral synthon in stereoselective reactions to introduce specific three-dimensional configurations into target molecules.
• Ligand Development: Utilized in the research and development of novel ligands for catalysis or receptor binding studies.
• Custom Synthesis: A starting material for contract research organizations (CROs) and CDMOs producing bespoke compounds for client projects.

Quality Control

Every batch of Ethanethioic Acid, S-[2-Amino-3-(2-Methylphenyl)Propyl] Ester (9Ci) is produced and analyzed under strict quality management protocols to ensure identity, purity, and consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing comprehensive analytical results from techniques such as HPLC, NMR, and MS to confirm specification adherence.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). The compound may be hygroscopic (moisture-sensitive); therefore, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
