Description

(S)-(-)-4-(Methoxymethyl)-1,3-Dioxolan-2-One CAS NO 135682-18-7 is a high-purity chiral cyclic carbonate derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its role as a versatile chiral synthon for constructing complex molecules with defined stereochemistry, essential for developing active pharmaceutical ingredients (APIs) and fine chemicals. This compound is primarily needed by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors seeking to produce enantiomerically pure products.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of enantiomerically pure drugs, particularly for cardiovascular and central nervous system (CNS) therapeutics.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides where specific stereochemistry is required for biological activity.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing chiral ligands and organocatalysts used in asymmetric synthesis.
• Polymer Chemistry: Acts as a monomer or co-monomer for creating novel biodegradable or functional polymers with specific stereoregularity.
• Fine Chemical Production: Employed in the multi-step synthesis of complex natural products, flavors, and fragrances.
• Academic & R&D: A valuable reagent for methodological development in organic chemistry and stereoselective transformation studies.

Quality Control

Our (S)-(-)-4-(Methoxymethyl)-1,3-Dioxolan-2-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure compliance with high-purity standards for research and industrial use. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance protocols.

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 may affect product stability and performance.
