Description

Sodium Ethoxide CAS NO 141-52-6 is a powerful alkoxide base commonly supplied as a white to yellowish powder or as a solution in ethanol. This versatile reagent is essential for driving a wide range of organic synthesis reactions, particularly where a strong, non-nucleophilic base is required. It is a critical raw material for manufacturers in the pharmaceutical, agrochemical, and fine chemical industries.

Application

• Pharmaceutical Synthesis: Key intermediate in the production of various APIs (Active Pharmaceutical Ingredients), used in Claisen condensations, alkoxylations, and dehydrohalogenation reactions.
• Biodiesel Production: Acts as a highly effective catalyst in the transesterification of triglycerides with methanol to produce fatty acid methyl esters (FAME).
• Agrochemical Manufacturing: Employed in the synthesis of pesticides, herbicides, and other crop protection agents.
• Polymer & Resin Industry: Used as a catalyst in polymerization reactions and in the production of specialty polymers and coatings.
• Fine Chemical Synthesis: Facilitates etherification, esterification, and condensation reactions for producing fragrances, flavors, and other specialty chemicals.
• Organic Laboratory Reagent: A staple base for deprotonation and elimination reactions in research and development settings.

Quality Control

Our Sodium Ethoxide is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, assay, and impurity profiles. Certificates of Analysis (COA) are provided with every shipment, detailing results from tests such as assay, moisture content, and identification. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (argon or nitrogen) to prevent decomposition. Store in a cool, dry, well-ventilated area away from incompatible materials such as acids, oxidizing agents, and moisture. Recommended storage temperature is 2-8°C for extended stability, though short-term storage at 15-25°C is acceptable for immediate use.
