Description

(R)-Methyl(α-Methylphenethyl)Ammonium [R-(R*,R*)]-Hydrogen Tartrate CAS NO 93777-08-3 is a high-purity chiral ammonium tartrate salt, serving as a critical intermediate in advanced pharmaceutical synthesis and fine chemical manufacturing. Its primary value lies in its role as a resolving agent and chiral auxiliary for the separation and production of enantiomerically pure compounds, which are essential for developing active pharmaceutical ingredients (APIs) with high stereoselectivity. This product is indispensable for research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors who require precise chirality control in their synthetic pathways.

Application

• Pharmaceutical Intermediate: Key chiral building block and resolving agent for the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs).
• Asymmetric Synthesis: Employed as a chiral auxiliary or catalyst in stereoselective organic reactions to control the formation of specific stereoisomers.
• Analytical Chemistry: Used as a reference standard or chiral selector in chromatographic methods (e.g., HPLC, GC) for enantiomeric separation and analysis.
• Agrochemical Research: Intermediate in the development of chiral pesticides and herbicides where biological activity is stereospecific.
• Fine Chemical Production: Serves as a precursor for other high-value chiral compounds used in flavors, fragrances, and advanced materials.
• Academic & R&D: Utilized in university and corporate research laboratories for method development and studies in stereochemistry.

Quality Control

Our (R)-Methyl(α-Methylphenethyl)Ammonium Hydrogen Tartrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure compliance with stringent specifications for pharmaceutical and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, chiral excess, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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, which can affect stability and purity.
