Description

(R)-o-Acetyllactic Acid Methyl Ester is a high-purity chiral building block and synthetic intermediate of significant importance in advanced organic synthesis. Its value lies in its enantiomerically pure (R)-configuration, which is critical for producing optically active compounds with specific biological activities. This product is essential for research and production in the pharmaceutical, agrochemical, and fine chemical industries, where precise stereochemistry is a key determinant of efficacy and safety.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of anti-inflammatory drugs, antibiotics, and other therapeutics.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, fungicides, and plant growth regulators where the specific stereoisomer enhances activity and reduces environmental impact.
• Fine Chemical Production: Serves as a versatile building block for creating complex molecules in perfumery, flavors, and advanced material science.
• Asymmetric Catalysis Research: Employed as a standard substrate or ligand precursor in the development and screening of new chiral catalysts and methodologies.
• Biochemical Research: Used in studies involving enzyme mechanisms and stereoselective biotransformations.

Quality Control

Every batch of (R)-o-Acetyllactic Acid Methyl Ester is produced under strict quality management systems. We employ advanced analytical techniques, including chiral HPLC, GC, and NMR, to guarantee high enantiomeric excess (ee) and chemical purity. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) with full analytical data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. For long-term storage, consider storing under an inert atmosphere to maintain optimal purity.
