Description

(S)-2-(Oxiran-2-Yl)Ethan-1-Ol CAS NO 95404-59-4 is a high-purity chiral epoxide derivative, a crucial building block in asymmetric synthesis. Its enantiomeric purity and reactive oxirane ring make it an indispensable intermediate for creating complex, optically active molecules. This compound is primarily sought by pharmaceutical R&D and fine chemical manufacturers for the production of active pharmaceutical ingredients (APIs), agrochemicals, and specialty materials.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of β-blockers, antiviral agents, and other enantiomerically pure drugs.
• Agrochemical Synthesis: Used in the production of chiral herbicides, fungicides, and plant growth regulators.
• Liquid Crystal & Advanced Material Precursor: Serves as a building block for chiral dopants and specialty polymers with specific optical properties.
• Asymmetric Catalysis Research: A valuable substrate for developing and testing new chiral catalysts and methodologies.
• Flavor & Fragrance Industry: Intermediate for the synthesis of enantiomerically defined aroma chemicals.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs for the production of client-specific target molecules in multi-step syntheses.

Quality Control

We supply (S)-2-(Oxiran-2-Yl)Ethan-1-Ol in high chemical and enantiomeric purity grades suitable for demanding synthetic applications. Our products undergo rigorous quality testing, including chiral HPLC analysis, to ensure compliance with stringent specifications. Certificates of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles are provided with each batch to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent hydrolysis of the epoxide ring.
