Sodium methoxide, ca 30% w/w in methanol

Description

CAS: 124-41-4 | CH3NaO | 54.024 g/mol

Sodium methoxide, ca 30% w/w in methanol is used in the preparation of high-spin hexanuclear Mn(III) cluster, [NaMn₆ (OMe)₁₂ (dbm)₆]⁺. It is useful in the synthesis of pharmaceuticals and agrochemicals. It serves as an initiator of anionic addition polymerization with ethylene oxide, forming a polyether with high molecular weight.

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.
