Description

Trifluoro-Methanesulfonic Acid Isoquinolin-8-Yl Ester is a specialized trifluoromethanesulfonate (triflate) ester derivative of isoquinoline, serving as a high-value synthetic intermediate. Its core value lies in its excellent leaving group properties, enabling efficient C-C and C-heteroatom bond formation in complex molecule construction. This compound is essential for researchers and process chemists in the pharmaceutical and agrochemical industries, particularly for the synthesis of active pharmaceutical ingredients (APIs) and advanced materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, especially in medicinal chemistry for creating complex heterocyclic scaffolds.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides where the isoquinoline moiety imparts specific biological activity.
• Cross-Coupling Reactions: Acts as a superior electrophile in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Stille, Negishi) for introducing the isoquinolin-8-yl group.
• Material Science Research: Employed in the creation of organic semiconductors, ligands for catalysis, and functionalized polymers.
• Laboratory Reagent: Serves as a specialized reagent in academic and industrial R&D for method development and exploratory synthesis.

Quality Control

Our Trifluoro-Methanesulfonic Acid Isoquinolin-8-Yl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and identity. Certificates of Analysis (COA) with detailed specifications are provided for every shipment, ensuring traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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.
