Description

3-Benzofurancarboxaldehyde,5-Fluoro-(9Ci) is a specialized fluorinated benzofuran derivative, serving as a crucial building block in advanced organic synthesis. Its core value lies in its unique molecular structure, which incorporates both a reactive aldehyde group and a fluorine atom on the benzofuran scaffold, enabling precise modifications for developing novel compounds. This high-purity intermediate is primarily needed by research institutions and pharmaceutical companies engaged in the discovery and development of new active pharmaceutical ingredients (APIs) and agrochemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly in medicinal chemistry programs targeting CNS disorders and oncology.
• Agrochemical Research: Used in the development of new-generation herbicides and fungicides, where the fluorine atom enhances biological activity and metabolic stability.
• Material Science: Serves as a monomer or functionalizing agent for creating specialty polymers and organic electronic materials with tailored properties.
• Chemical Synthesis: Employed as a versatile aldehyde component in cross-coupling reactions, condensations, and as a starting material for heterocyclic chemistry.
• Fluorine Chemistry Studies: Utilized in academic and industrial R&D to study the effects of fluorine substitution on the reactivity and physical properties of heteroaromatic systems.

Quality Control

Our 3-Benzofurancarboxaldehyde,5-Fluoro-(9Ci) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, GC for residual solvents, and NMR/IR for structural confirmation. We provide full traceability and detailed Certificates of Analysis (COA) with every shipment, confirming compliance with customer specifications and relevant industry standards for fine chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation and light, prolonged exposure to air or direct light should be avoided. Keep away from heat and incompatible materials.
