Description

(S)-Methyl(α-Methylphenethyl)Ammonium [R-(R*,R*)]-Hydrogen Tartrate CAS NO 62265-33-2 is a high-purity chiral ammonium tartrate salt, serving as a critical intermediate in asymmetric synthesis and pharmaceutical development. Its primary value lies in its role as a resolving agent or a precursor for chiral catalysts and active pharmaceutical ingredients (APIs), enabling the production of enantiomerically pure compounds. This product is essential for research and manufacturing in the pharmaceutical, agrochemical, and fine chemical industries, where precise stereochemistry is paramount for efficacy and regulatory approval.

Application

• Chiral Resolution Agent: Used for the separation of racemic mixtures of acids, amines, and other compounds in pharmaceutical synthesis.
• Asymmetric Synthesis Catalyst Precursor: Serves as a building block for developing chiral phase-transfer catalysts or organocatalysts.
• Pharmaceutical Intermediate: A key starting material or intermediate in the synthesis of enantiomerically pure drugs, particularly in central nervous system (CNS) and cardiovascular therapeutics.
• Agrochemical Synthesis: Employed in the production of chiral pesticides and herbicides to enhance biological activity and reduce environmental impact.
• Fine Chemical Production: Utilized in the manufacture of specialty chemicals, flavors, and fragrances requiring specific stereochemistry.
• Academic & Industrial Research: A valuable reagent for methodological development in organic chemistry and process chemistry R&D.

Quality Control

Our (S)-Methyl(α-Methylphenethyl)Ammonium Hydrogen Tartrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assay and impurity profiling, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data (HPLC, Chiral HPLC) are provided to guarantee consistent quality, identity, and purity for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent exposure to atmospheric moisture. For long-term storage, consider using desiccants.
