Description

Cyclohexanecarbonyl Chloride, 4-Butyl-, trans- (9Ci) is a specialized organic intermediate featuring a trans-configured butyl-substituted cyclohexane ring coupled with a highly reactive acid chloride functional group. This compound matters for its role as a key building block in the synthesis of complex molecules, enabling the introduction of a lipophilic, sterically defined cyclohexylbutyl moiety. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for creating novel active ingredients, as well as by manufacturers of advanced materials and liquid crystals.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for candidates targeting central nervous system (CNS) disorders or requiring specific stereochemistry.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and plant growth regulators where the cyclohexylbutyl group can influence bioavailability and activity.
• Liquid Crystal Materials: Serves as a starting material for the synthesis of chiral dopants and other components used in liquid crystal displays (LCDs) due to its rigid, substituted cyclohexane structure.
• Organic Synthesis & Research: Employed in academic and industrial R&D labs for constructing complex organic frameworks, including natural product analogs and novel polymers.
• Fine Chemical Production: Acts as an acylating agent in the manufacture of specialty chemicals, such as fragrances, dyes, and performance additives.

Quality Control

Our Cyclohexanecarbonyl Chloride, 4-Butyl-, trans- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical processes.

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). This product is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and strong bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and to maintain purity.
