Description

3-Cyclopropyl-4-Fluorobenzaldehyde is a high-purity fluorinated aromatic aldehyde building block of significant interest in advanced organic synthesis. Its core value lies in the unique reactivity of the aldehyde group combined with the steric and electronic properties imparted by the cyclopropyl and fluorine substituents, enabling the construction of complex molecular architectures. This compound is primarily needed by research and development chemists and process scale-up teams within the pharmaceutical and agrochemical industries for the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of novel drug candidates, particularly in medicinal chemistry programs targeting CNS disorders, anti-infectives, and oncology.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the fluorinated cyclopropyl moiety can enhance biological activity and environmental stability.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands and organocatalysts used in asymmetric synthesis and cross-coupling reactions.
• Material Science Research: Employed in the synthesis of functionalized organic molecules for advanced materials, such as liquid crystals or organic semiconductors.
• Custom Synthesis and Contract Manufacturing: A critical starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving global clients.

Quality Control

Every batch of 3-Cyclopropyl-4-Fluorobenzaldehyde is manufactured and tested under strict quality management systems. Our products undergo rigorous quality testing, including HPLC, GC, and NMR analysis, to ensure compliance with industry standards and customer specifications. 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 room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
