Description

L-Iditol,1,4:3,6-Dianhydro- is a high-purity, bicyclic sugar alcohol derivative, also known as isosorbide. This versatile chiral building block is valued for its rigid molecular structure and derivatization potential, enabling the synthesis of advanced materials and fine chemicals. It is essential for manufacturers in the pharmaceutical, polymer, and specialty chemical industries seeking sustainable, bio-based intermediates for high-performance applications.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the production of active pharmaceutical ingredients (APIs), particularly cardiovascular and diuretic drugs.
• Polymer & Plasticizer Production: Serves as a renewable, non-toxic monomer for synthesizing biodegradable polyesters (e.g., polyisosorbide succinate) and as a green plasticizer.
• Specialty Chemical Synthesis: Used as a precursor for surfactants, solvents, and other functional chemicals due to its hydroxyl groups.
• Cosmetic & Personal Care Formulations: Employed as a humectant and moisturizing agent in high-end skincare products.
• Food Additive Carrier: Functions as a carrier or bulking agent for flavors, colors, and sweeteners in food-grade applications.
• Research & Development: A valuable standard and starting material in organic chemistry and materials science research.

Quality Control

Our L-Iditol,1,4:3,6-Dianhydro- is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) detailing results from HPLC, GC, and other relevant methods are provided to guarantee traceability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 stability and handling properties.
