Description

2H-Pyran-2-Carboxaldehyde, Tetrahydro- is a versatile heterocyclic aldehyde building block, also known as tetrahydro-2H-pyran-2-carboxaldehyde. This compound is valued for its reactive aldehyde group within a protected, saturated pyran ring, making it a crucial intermediate for synthesizing complex molecules. It is primarily sought after by research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for constructing chiral centers and functionalized ring systems.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those containing chiral tetrahydrofuran or tetrahydropyran motifs.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where its structure contributes to biological activity.
• Fine Chemical Production: Serves as a precursor for flavors, fragrances, and specialty polymers requiring specific cyclic ether functionalities.
• Organic Synthesis Reagent: Employed in academic and industrial R&D for cyclization reactions, nucleophilic additions, and as a protecting group precursor.
• Material Science Research: Investigated as a monomer or cross-linking agent for novel polymeric materials with tailored properties.

Quality Control

Our 2H-Pyran-2-Carboxaldehyde, Tetrahydro- is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including GC/HPLC for purity, identity confirmation by FT-IR and NMR, and checks for residual solvents and moisture to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flame.
