Product Name:Sodium ethoxide
English Name:Sodium ethoxide
CAS No.:141-52-6
Aliases:Sodium ethylate, Sodium ethylate (ethanol solution)
Molecular Formula:C2H5NaO
Physical Properties:White or slightly yellow hygroscopic powder, decomposes upon contact with water. Melting point 260°C, boiling point 91°C, relative density 0.868 g/mL, flash point 48°F (about 8.9°C), soluble in ethanol.
Uses:Sodium ethoxide has strong alkalinity and is commonly used in organic synthesis to abstract active hydrogen from organic compounds, such as in Claisen ester condensation and malonic ester synthesis. It is also used in the synthesis of pesticides, where it can undergo nucleophilic addition with ester carbonyls for transesterification, or abstract alpha-hydrogen to form enolate structures.
Technical Specifications:
Purity ≥99%
Packaging: 25kg/drum
Appearance: white or slightly yellow powder
Storage: sealed, dry, protected from light
