Description

Cycloheptanone, 2-(3Z)-3-Hexenyl-2-Methyl-, (2S)- (9Ci) CAS NO 802903-35-1 is a chiral, optically active ketone derivative characterized by a unique seven-membered ring structure and an unsaturated side chain. This compound is valued for its role as a sophisticated chiral building block and intermediate in the synthesis of complex organic molecules, where its stereochemistry and functional groups are critical. It is primarily sought by research and development teams in the pharmaceutical, agrochemical, and specialty fragrance industries for creating novel active ingredients and high-value fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of novel active pharmaceutical ingredients (APIs), particularly for compounds targeting the central nervous system or metabolic pathways.
• Agrochemical Synthesis: Used in the production of advanced, stereospecific pesticides and herbicides, where the specific spatial orientation of the molecule can influence biological activity and environmental degradation.
• Fragrance & Flavor Chemistry: Acts as a precursor for the synthesis of unique macrocyclic and musky odorants, contributing to complex scent profiles in high-end perfumery.
• Material Science Research: Investigated as a monomer or cross-linking agent in the development of specialized polymers with tailored optical or mechanical properties.
• Organic Synthesis Reagent: Employed in academic and industrial laboratories for methodological studies in asymmetric synthesis, including cycloaddition and conjugate addition reactions.
• Ligand & Catalyst Development: Utilized as a backbone for creating novel chiral ligands and organocatalysts used in enantioselective transformations.

Quality Control

Our production of Cycloheptanone, 2-(3Z)-3-Hexenyl-2-Methyl-, (2S)- (9Ci) adheres to stringent quality 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 optical rotation measurement to confirm identity, enantiomeric excess (ee), and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory 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 at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, the container should be kept sealed after each use to minimize exposure to air.
