Sodium methoxide solution 0.5 M is a strong base used primarily for derivatizing compounds in gas chromatography (GC) to improve their volatility and stability. This reagent acts as a base catalyst for transesterifying esterified lipids, such as glycerides and phospholipids, into fatty acid methyl esters (FAMEs), enhancing separation and detection. More broadly, sodium methoxide serves as an alkaline catalyst for producing biodiesel methyl esters, a base for condensation reactions in organic synthesis, and an intermediate for pharmaceuticals. The product has a CAS number of 124-41-4, a molecular formula of CH3ONa, and a molecular weight of 54.02 g/mol. It is stored at ambient conditions but requires careful handling, as it carries a Danger signal word: it is highly flammable, toxic if swallowed, in contact with skin or if inhaled, causes severe skin burns and eye damage, and causes damage to organs. Molekula supplies Sodium methoxide solution 0.5 M from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
