Description

2-Cyclohexene-1-Carbonyl Chloride, 4-Methyl-, cis- (9Ci) is a specialized organic acid chloride intermediate featuring a reactive carbonyl chloride group on a substituted cyclohexene ring. This compound is valued for its role as a key building block in the synthesis of more complex molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists working in fine chemical synthesis, where it enables the introduction of the 4-methyl-cis-cyclohexenecarbonyl moiety.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of active pharmaceutical ingredients (APIs), especially those requiring a specific cis-cyclohexene geometry.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and plant growth regulators.
• Ligand and Catalyst Development: Serves as a precursor for creating chiral ligands or organometallic catalysts used in asymmetric synthesis.
• Polymer Chemistry: Can be employed to introduce functional side chains or cross-linking agents into polymer backbones.
• Organic Synthesis Research: A versatile reagent for acylations and the formation of amides, esters, and ketones in academic and industrial R&D settings.
• Material Science: Potential use in the synthesis of advanced organic materials with specific optical or electronic properties.

Quality Control

Our 2-Cyclohexene-1-Carbonyl Chloride, 4-Methyl-, cis- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to ensure full traceability and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Recommended storage temperature is 2-8°C for long-term stability.
