Description

Cyclopentanecarboxylic Acid, 1-(1,1-Dimethyl-2-Propenyl)-2-Methyl-, (1R,2S)-Rel- (9Ci) is a high-purity, stereochemically defined chiral building block of significant interest in advanced organic synthesis. This compound matters as a versatile intermediate for constructing complex molecular architectures, particularly in the development of active pharmaceutical ingredients (APIs) and specialty agrochemicals. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries seeking to introduce specific stereocenters and functional groups into target molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel therapeutic agents, including potential antiviral, anti-inflammatory, or central nervous system (CNS) active compounds.
• Agrochemical Synthesis: Used in the production of advanced, stereoselective pesticides and herbicides where the specific spatial orientation of the molecule is critical for biological activity.
• Fine Chemical Manufacturing: Serves as a specialized building block for synthesizing complex flavors, fragrances, and other high-value specialty chemicals.
• Academic & Industrial Research: Employed in methodological studies and catalysis research for developing new asymmetric synthesis routes and C-C bond formation strategies.
• Material Science Precursor: Potential use in the synthesis of chiral ligands for catalysts or advanced polymeric materials with specific stereochemical properties.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We employ advanced analytical techniques including HPLC, GC, chiral analysis, and NMR to verify identity, purity, and stereochemical integrity. Certificates of Analysis (COA) documenting batch-specific results are available upon request. Our quality system is designed to support cGMP requirements for pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its nature as a strong acid/organic solvent, store separately from incompatible materials such as bases, oxidizing agents, and reactive metals.
