Description

(3R-Cis)-(-)-2 3-Dihydro-7A-Me-3-Ph-Pyr& CAS NO 302911-95-1 is a high-purity, stereochemically defined chiral intermediate of significant importance in advanced organic synthesis. Its precise cis-(3R) configuration makes it a valuable building block for the development of enantiomerically pure pharmaceuticals and fine chemicals. This compound is essential for research and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries who require reliable access to high-quality chiral synthons.

Application

• Pharmaceutical Intermediate: Key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and cardiovascular drugs.
• Asymmetric Catalysis Research: Used as a ligand precursor or a model substrate in the development and study of new asymmetric catalytic reactions.
• Agrochemical Synthesis: Serves as a building block for creating enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances where specific stereochemistry is required.
• Academic & R&D Laboratories: A critical reagent for methodological studies in organic chemistry and medicinal chemistry programs.

Quality Control

Our (3R-Cis)-(-)-2 3-Dihydro-7A-Me-3-Ph-Pyr& CAS NO 302911-95-1 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure high enantiomeric excess (ee) and chemical purity suitable for sensitive synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to light and oxidation, prolonged exposure to air or light should be avoided. Keep away from heat and incompatible materials.
