Description

(R)-Mop CAS NO 145964-33-6 is a high-purity chiral intermediate of significant importance in asymmetric synthesis. Its primary value lies in its role as a key building block for the production of active pharmaceutical ingredients (APIs) and other fine chemicals requiring specific stereochemistry. This compound is essential for research and manufacturing in the pharmaceutical, agrochemical, and advanced materials sectors, where precise molecular configuration is critical for efficacy and performance.

Application

• Pharmaceutical Intermediate: A crucial chiral building block in the synthesis of novel APIs, particularly for central nervous system (CNS) and cardiovascular drugs.
• Asymmetric Catalyst Ligand Precursor: Used in the development and preparation of chiral ligands for transition metal catalysis.
• Agrochemical Synthesis: Employed in the research and production of enantiomerically pure pesticides and herbicides.
• Academic & Industrial R&D: Serves as a standard or starting material in methodological development for stereoselective organic transformations.
• Fine Chemical Production: Integral to manufacturing specialty chemicals where the (R)-enantiomer imparts desired physical or biological properties.

Quality Control

Our (R)-Mop is manufactured under strict quality management systems to ensure batch-to-batch consistency and high enantiomeric purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as chiral purity, chemical purity, and impurity profiles. Our quality commitment aligns with cGMP standards where applicable, supporting its use in regulated pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. For long-term storage, consider desiccated conditions.
