Description

(S)-(-)-Lactamide CAS NO 89673-71-2 is a high-purity chiral building block and intermediate of significant importance in asymmetric synthesis. Its defined stereochemistry makes it a valuable precursor for the production of pharmaceuticals, fine chemicals, and advanced materials. This compound is particularly sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for developing enantiomerically pure active ingredients.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of enantiomerically pure drugs, particularly in the development of antibiotics, antivirals, and other bioactive molecules.
• Asymmetric Synthesis: Used as a starting material or auxiliary in catalytic asymmetric reactions to introduce stereocenters with high enantiomeric excess.
• Fine Chemical Production: Serves as a building block for complex organic molecules used in flavors, fragrances, and advanced materials.
• Biochemical Research: Employed in enzymatic studies and as a substrate or inhibitor for lactamases and other enzymes.
• Agrochemical Synthesis: Intermediate in the production of chiral pesticides and herbicides where specific stereochemistry is required for activity.
• Polymer Science: Potential monomer or modifier for creating polymers with specific chiral properties or biodegradability.

Quality Control

Our (S)-(-)-Lactamide is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing identity, purity (assay), enantiomeric excess, and impurity profiles are provided with every shipment.

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 stability and handling properties. For long-term storage, consider using desiccants.
