CAS 124-41-4 Sodium Methoxide Solid
Overview
Sodium Methoxide (sodium methanolate, CH₃ONa, CAS 124-41-4) is a strong alkoxide base and efficient transesterification catalyst widely used in biodiesel production, pharmaceuticals, agrochemicals, and fine chemicals. Supplied as a white solid or as 27–32% w/w solutions in methanol, it promotes ester exchange, condensation, and selective deprotonation steps with fast kinetics. Our grades feature low moisture and carbonate for consistent activity and stable titration values, with COA/TDS available per batch. Highly moisture-sensitive and caustic—store and handle in dry, inert conditions and consult the SDS before use.
Product Description
CAS 124-41-4 Sodium Methoxide
Sodium methoxide is a robust alkoxide base and highly efficient catalyst widely used in biodiesel manufacture, pharmaceutical and agrochemical synthesis, polymer modification, and fine chemicals. As a strong base and transesterification promoter, it accelerates ester exchange, condensation (e.g., Claisen/Knoevenagel), and selective deprotonation/alkylation steps with fast kinetics and clean profiles. Available as 27–32% solutions in methanol or low-carbonate solids, it offers high basicity, good solubility in methanol systems, and excellent catalytic turnover—making it a cost-effective, scalable choice from R&D to continuous industrial production.
