Description

2H-Cyclopropa[F]Benzofuran-5-Carbonyl Chloride, Octahydro-2-Oxo- (9Ci) is a specialized, high-purity chemical building block characterized by its fused cyclopropa-benzofuran core and reactive acid chloride functionality. This compound matters as a critical intermediate for the synthesis of complex molecules, enabling the introduction of a carbonyl moiety under mild conditions. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for constructing novel active ingredients and exploring new chemical spaces.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for complex heterocyclic targets.
• Agrochemical Synthesis: Used in the creation of novel herbicides, fungicides, and insecticides that require its unique bridged molecular architecture.
• Material Science Research: Acts as a precursor for advanced polymers or organic electronic materials due to its rigid, fused-ring structure.
• Chemical Biology Probes: Employed in the synthesis of activity-based probes or molecular tags for studying biological systems.
• Custom Synthesis & Contract Manufacturing: A valuable starting material for fine chemical manufacturers offering bespoke synthesis services to clients.
• Academic Research: Utilized in university and institutional labs for methodological development and exploring new reaction pathways in organic chemistry.

Quality Control

Every batch of 2H-Cyclopropa[F]Benzofuran-5-Carbonyl Chloride, Octahydro-2-Oxo- (9Ci) is produced and tested under strict quality management protocols to ensure consistency and reliability for your critical synthesis work. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
