Description

Isomannide is a high-purity, versatile bicyclic diol derived from renewable resources, serving as a key chiral building block in advanced chemical synthesis. Its rigid V-shaped structure and dual hydroxyl functionality make it an exceptional monomer for creating high-performance, sustainable polymers with enhanced thermal and mechanical properties. This compound is essential for R&D and production in the pharmaceutical, polymer, and specialty chemical industries seeking bio-based alternatives.

Application

• Pharmaceutical Intermediate: A crucial chiral precursor for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring specific isomeric purity.
• Polymer Chemistry: A core monomer for producing polycarbonates, polyesters, and polyurethanes, imparting rigidity, thermal stability, and biodegradability to the resulting materials.
• Green Chemistry & Sustainable Materials: A foundational component in the development of bio-based plastics and resins, supporting circular economy initiatives.
• Cosmetic & Personal Care Ingredients: Used in the synthesis of specialty esters and polymers that function as emulsifiers, film-formers, or delivery agents.
• Liquid Crystal & Electronic Materials: Employed as a rigid backbone in the synthesis of monomers for liquid crystal displays (LCDs) and other advanced electronic applications.
• Cross-linking Agent: Functions as a polyfunctional cross-linker in coatings, adhesives, and elastomers to enhance network density and performance.

Quality Control

Our Isomannide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and chiral purity assessment, to ensure it meets stringent specifications for advanced applications. A Certificate of Analysis (COA) detailing identity, assay, impurity profile, and physical parameters is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality and handling properties.
