Description

Oxiranecarbonyl Chloride, 3-Methyl-3-Phenyl-, trans- (9Ci) is a specialized chiral epoxide derivative that serves as a high-value synthetic intermediate. Its unique structure, featuring a phenyl-substituted oxirane ring and an acid chloride functional group, makes it a critical building block for the stereoselective synthesis of complex molecules. This compound is primarily sought by research and development teams in the pharmaceutical and advanced agrochemical sectors for constructing active pharmaceutical ingredients (APIs) and novel bioactive compounds.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of enantiomerically pure drug candidates and active pharmaceutical ingredients (APIs).
• Agrochemical Research: Building block for developing novel, stereospecific herbicides, fungicides, and plant growth regulators.
• Liquid Crystal & Advanced Material Synthesis: Precursor for creating chiral dopants and monomers used in liquid crystal displays (LCDs) and specialty polymers.
• Asymmetric Catalysis Ligand Synthesis: Used in the preparation of chiral ligands and organocatalysts for stereoselective transformations.
• Fine Chemical Production: Intermediate in the multi-step synthesis of complex fragrance and flavor compounds requiring specific stereochemistry.

Quality Control

Our Oxiranecarbonyl Chloride, 3-Methyl-3-Phenyl-, trans- (9Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive synthetic applications. We provide comprehensive Certificates of Analysis (COA) with each batch, detailing purity, enantiomeric excess, and impurity profiles. Our quality systems are designed to support cGMP and ISO standards for advanced chemical intermediates.

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 moisture-sensitive (hygroscopic) nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity. Keep away from heat, sparks, and open flame.
