Description

3-Fluoro-4-(Oxetan-3-Yloxy)Benzonitrile is a high-value pharmaceutical intermediate and versatile chemical building block. Its molecular structure, featuring a benzonitrile core, a fluorine substituent, and an oxetane ether linkage, makes it a critical synthon for medicinal chemistry research and advanced organic synthesis. This compound is primarily sought after by R&D chemists and process development scientists in the pharmaceutical and agrochemical industries for constructing novel active molecules.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for kinase inhibitors and other small-molecule therapeutics.
• Medicinal Chemistry Research: Used in hit-to-lead and lead optimization campaigns to explore structure-activity relationships (SAR) due to its fluorine atom and oxetane moiety, which can improve metabolic stability and membrane permeability.
• Agrochemical Synthesis: Serves as a precursor in the development of new herbicides, fungicides, and insecticides, where the fluorine and nitrile groups are common pharmacophores.
• Ligand and Catalyst Development: Employed in the preparation of specialized ligands for catalysis or as a core structure in functional materials.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for custom synthesis projects at various scales, from gram to kilogram quantities.

Quality Control

We maintain a strict quality management system to ensure batch-to-batch consistency and high purity for research and development use. Our standard offering for this intermediate typically meets a purity specification of ≥95% (by HPLC), with comprehensive identity confirmation via NMR and mass spectrometry. A Certificate of Analysis (COA) detailing purity, identity, and impurity profile is provided with every shipment. We can also supply material under GMP-like conditions for advanced non-clinical studies, with specifications tailored to project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (typically 15-25°C). The compound may be hygroscopic (moisture-sensitive); therefore, containers should be kept tightly sealed and under an inert atmosphere for long-term storage to maintain stability.
