Description

Benzeneethanol, -α-,2-Dimethyl-, (-α-R)- (9Ci) is a chiral, substituted phenethyl alcohol derivative of significant interest in fine chemical synthesis. Its value lies in its role as a versatile chiral building block or intermediate for the development of pharmaceuticals, agrochemicals, and advanced materials. This compound is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating enantiomerically pure target molecules. The CAS number for this specific stereoisomer is 851885-37-5.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) agents or other therapeutic molecules requiring specific stereochemistry.
• Agrochemical Synthesis: Used in the research and production of enantiomerically pure pesticides, herbicides, or plant growth regulators where biological activity is stereospecific.
• Ligand and Catalyst Development: Acts as a precursor for chiral ligands used in asymmetric catalysis, such as phosphines or nitrogen donors, to control stereoselectivity in chemical reactions.
• Fragrance and Flavor Chemistry: Potential use in the synthesis of complex, high-value aroma chemicals where the specific stereoisomer imparts a distinct olfactory profile.
• Material Science Research: Investigated as a monomer or modifying agent for creating chiral polymers or liquid crystals with specialized optical or electronic properties.
• Academic and Industrial R&D: Employed in methodological studies and process chemistry development for exploring new asymmetric synthetic routes.

Quality Control

Our Benzeneethanol, -α-,2-Dimethyl-, (-α-R)- (9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC or GC, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles are provided with every shipment. We support cGMP compliance for pharmaceutical development and can tailor specifications to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
