Description

2-Nitro-4-(Trifluoromethoxy)Phenyl Triflate, also known as 5-(Trifluoromethoxy)-2-{[(Trifluoromethyl)Sulphonyl]Oxy}Nitrobenzene, is a high-value, multi-functional chemical building block prized for its unique trifluoromethoxy and triflate ester functionalities. This compound is critical for introducing specific aromatic nitro and triflate leaving groups into complex molecular architectures, enabling advanced synthetic pathways. It is primarily sought after by R&D chemists and process development teams in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and specialty materials.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring fluorinated aromatic systems for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides where the trifluoromethoxy group imparts desirable biological activity and environmental persistence profiles.
• Material Science Research: Acts as a monomer or functionalization agent in the development of specialty polymers, liquid crystals, and organic electronic materials.
• Cross-Coupling Reactions: The phenyl triflate moiety is an excellent substrate for palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Stille, Sonogashira) to form biaryl and other complex structures.
• Fluorine Chemistry: An essential reagent for medicinal and synthetic chemists exploring structure-activity relationships (SAR) by introducing fluorinated motifs.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for custom synthesis projects and scale-up campaigns.

Quality Control

Every batch of 2-Nitro-4-(Trifluoromethoxy)Phenyl Triflate is manufactured and tested under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and batch-to-batch consistency suitable for demanding R&D and scale-up applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Keep away from heat, sparks, and open flame.
