Description

Cyclopentanol, 1,2-Dimethyl-3-(1-Methylethylidene)-, (1R,2R)-Rel- (9Ci) is a high-purity, stereochemically defined chiral compound that serves as a critical building block in advanced organic synthesis. Its value lies in its complex, functionalized cyclopentane core, which is essential for constructing molecules with specific three-dimensional architectures. This intermediate is particularly needed by pharmaceutical and agrochemical R&D teams for the development of novel active ingredients, as well as by specialty chemical manufacturers producing fine chemicals and flavors.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of new drug candidates, particularly in therapeutic areas requiring stereochemical precision.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides where the specific stereochemistry can influence biological activity.
• Fine Chemical Production: Serves as a precursor in the manufacture of complex fragrance and flavor ingredients.
• Academic & Industrial Research: A valuable reagent for methodological studies in asymmetric synthesis and catalysis.
• Material Science: Potential use as a monomer or modifier in the synthesis of specialized polymers with unique properties.

Quality Control

Our production of Cyclopentanol, 1,2-Dimethyl-3-(1-Methylethylidene)-, (1R,2R)-Rel- (9Ci) adheres to stringent quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is characterized using advanced analytical techniques including chiral HPLC, GC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profile is provided with every shipment, supporting your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C/59-77°F). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
