Description

[R,(+)]-2-Bromopropanoic Acid Methyl Ester is a high-purity chiral building block essential for asymmetric synthesis. This optically active ester is a critical intermediate for the production of pharmaceuticals, agrochemicals, and advanced materials. It is primarily sought by research institutions and industrial manufacturers in the life sciences sector for constructing complex molecules with defined stereochemistry.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of anti-inflammatory and antiviral drugs.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides and pesticides for enhanced efficacy and environmental safety.
• Ligand and Catalyst Preparation: Serves as a precursor for chiral ligands and organocatalysts used in asymmetric catalysis.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances requiring specific stereochemistry.
• Academic and R&D: A valuable reagent in organic chemistry research for methodological development and total synthesis projects.
• Material Science: Potential monomer or intermediate for creating chiral polymers and liquid crystals.

Quality Control

Our [R,(+)]-2-Bromopropanoic Acid Methyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity (enantiomeric excess) determination by chiral HPLC or GC, chemical assay, and identity confirmation. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

Storage

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