Description

Cyclobutanecarbonyl Chloride, 3-Butyl- (9Ci) is a specialized organic acid chloride derivative of cyclobutane, serving as a critical building block in advanced organic synthesis. This compound matters for its role as a reactive acylating agent, enabling the efficient introduction of the sterically defined 3-butylcyclobutanecarbonyl moiety into target molecules. It is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for constructing novel active ingredients and complex intermediates.

Application

• Pharmaceutical Intermediate: Key reagent in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders or metabolic diseases.
• Agrochemical Synthesis: Used to create advanced pesticide and herbicide molecules with specific steric and electronic properties.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of specialty polymers with unique thermal or mechanical characteristics.
• Peptide Mimetics: Employed to incorporate cyclobutane-based, non-natural amino acid analogs into peptide chains for biological activity studies.
• Ligand and Catalyst Development: Serves as a precursor for synthesizing specialized ligands used in asymmetric catalysis and metal-organic frameworks (MOFs).
• Fine Chemical Production: Utilized in multi-step syntheses of complex fragrance and flavor ingredients requiring specific carbon frameworks.

Quality Control

Our Cyclobutanecarbonyl Chloride, 3-Butyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as bases, alcohols, and oxidizing agents.
