Description

1-Oxaspiro[4.4]Nonane-2,6-Diol, (5S,6S)- (9Ci) is a high-purity, stereochemically defined spirocyclic compound, serving as a sophisticated chiral building block in advanced organic synthesis. Its unique fused oxaspiro structure and dual hydroxyl functionality make it a valuable intermediate for constructing complex molecular architectures with precise three-dimensional control. This compound is primarily targeted at research and development chemists in the pharmaceutical and agrochemical industries, where it is used to develop novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of new active pharmaceutical ingredients (APIs), particularly in programs targeting central nervous system (CNS) disorders or infectious diseases.
• Agrochemical Synthesis: Used in the creation of novel, stereospecific herbicides, fungicides, or insecticides where the specific spatial orientation of the molecule is critical for bioactivity.
• Asymmetric Catalyst Ligand Precursor: The defined stereocenters and hydroxyl groups provide a foundation for synthesizing novel chiral ligands used in asymmetric catalysis.
• Fine Chemical and Specialty Material Production: Employed in the synthesis of complex fragrances, flavors, or advanced materials requiring specific stereochemistry.
• Academic and Industrial R&D: Serves as a valuable reference standard and starting material in methodological development and exploration of new spirocyclic chemistry.

Quality Control

Our 1-Oxaspiro[4.4]Nonane-2,6-Diol, (5S,6S)- (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification and impurity profiling, to ensure it meets the high standards required for research and process development. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and other critical specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, it is recommended to handle the material under a dry inert atmosphere (e.g., nitrogen or argon) for long-term storage or after opening to prevent moisture uptake. Recommended storage temperature is 2-8°C for prolonged stability.
