Description

1-Cyclopentene-1-Carboxaldehyde, 4,5-Dimethyl-, cis- (8Ci) is a specialized, high-value aldehyde derivative of a substituted cyclopentene, serving as a critical chiral building block and intermediate in advanced organic synthesis. Its unique cis-dimethylated cyclopentene backbone makes it valuable for constructing complex molecular architectures with precise stereochemistry. This compound is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for applications requiring specific spatial orientation and functional group manipulation.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the development of novel active pharmaceutical ingredients (APIs), particularly in therapeutic areas requiring complex carbocyclic or fused-ring systems.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where its structural motif can contribute to biological activity and selectivity.
• Fine Chemical & Fragrance Ingredient: Serves as a precursor for synthesizing specialty aroma chemicals and flavors due to its reactive aldehyde functionality and specific stereochemistry.
• Academic & Industrial Research: Employed in methodological studies, catalysis research (e.g., asymmetric synthesis), and the exploration of new chemical spaces in medicinal chemistry.
• Material Science Precursor: Potential use in synthesizing specialized monomers or ligands for polymers and advanced functional materials.

Quality Control

Every batch of 1-Cyclopentene-1-Carboxaldehyde, 4,5-Dimethyl-, cis- (8Ci) is produced and tested under strict quality management protocols to ensure consistency and purity for sensitive synthetic applications. Our products undergo rigorous quality testing, including chiral purity analysis, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your regulatory and R&D documentation needs.

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 area. Recommended storage temperature is 2-8°C for long-term stability. Allow the container to reach ambient temperature before opening to minimize moisture ingress and degradation. Keep away from strong oxidizing agents.
