Description

1,2-Oxathiete (CAS NO 70494-92-7) is a specialized heterocyclic compound containing both oxygen and sulfur within a four-membered ring structure. This unique chemical architecture makes it a valuable intermediate and building block in advanced synthetic organic chemistry and materials science research. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for constructing novel molecular frameworks.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for constructing complex heterocyclic cores.
• Agrochemical Synthesis: Used as a building block in the discovery and synthesis of novel herbicides, fungicides, and insecticides with unique modes of action.
• Ligand and Catalyst Development: Employed in organometallic chemistry for the preparation of novel ligands and catalysts due to its potential chelating properties.
• Polymer and Materials Science: Investigated as a monomer or cross-linking agent for the development of specialty polymers with specific thermal or chemical resistance properties.
• Chemical Research Reagent: Utilized in academic and industrial laboratories for studying ring-strain reactions, cycloadditions, and other fundamental organic transformations.
• Fine Chemical Production: Acts as a precursor in the multi-step synthesis of complex fragrance, flavor, and dye molecules.

Quality Control

Our 1,2-Oxathiete is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and development applications. Each lot is characterized using advanced analytical techniques including NMR, GC-MS, and HPLC. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place, preferably at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to the reactive nature of strained heterocycles, it is recommended to store under an inert atmosphere for long-term stability and to minimize potential decomposition.
