Sodium methoxide, 98%, Thermo Scientific Chemicals
Descrizione
Sodium methoxide is used as a base and a reagent in organic chemistry. It is useful in the synthesis of pharmaceuticals and agrochemicals. It acts as a nucleophile and is used in the production of methyl ethers. It serves as an initiator of anionic addition polymerization with ethylene oxide, forming a polyether with high molecular weight. It is involved in the production of biodiesel from vegetable oils and animal fats.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
