Description

2-Butanone, 4-Methoxy-3-Methyl-, (R)- (9Ci) is a chiral, highly volatile organic compound with significant utility in advanced chemical synthesis. This optically active building block is crucial for creating molecules with specific three-dimensional configurations, which is essential for developing pharmaceuticals and agrochemicals with targeted biological activity. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for the synthesis of enantiomerically pure intermediates.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: A key building block for the production of enantiomerically pure active pharmaceutical ingredients (APIs), particularly in central nervous system (CNS) and cardiovascular drug candidates.
• Agrochemical Precursor: Used in the research and development of chiral pesticides and herbicides, where the specific stereochemistry can influence efficacy and environmental safety.
• Advanced Material Synthesis: Serves as a monomer or modifier in the development of specialty polymers and liquid crystals with specific optical properties.
• Flavor and Fragrance Chemistry: Employed as a chiral synthon for creating stereochemically defined aroma chemicals and flavoring agents.
• Catalyst and Ligand Development: Acts as a precursor for synthesizing novel chiral ligands and organocatalysts used in asymmetric synthesis.
• Academic and Industrial Research: A valuable reagent for methodological studies in organic chemistry and asymmetric catalysis.

Quality Control

Our production of (R)-4-Methoxy-3-methyl-2-butanone adheres to stringent quality management protocols to ensure batch-to-batch consistency and high enantiomeric purity. Every lot is supported by a comprehensive Certificate of Analysis (COA) detailing critical parameters such as chiral purity (by chiral GC or HPLC), chemical purity, and identity confirmation. We operate under a quality system designed to meet the exacting standards of cGMP and ISO guidelines for fine chemical manufacturing, providing the reliability required for advanced research and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at a controlled room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Keep away from heat, sparks, and open flame.
