CAS 141-52-6 Sodium ethoxide
Overview
Sodium Ethoxide (sodium ethylate, CAS 141-52-6, C₂H₅ONa) is a strong alkoxide base widely used in biodiesel ethyl ester production, pharmaceuticals, agrochemical intermediates, polymer modification, and fine chemicals. It efficiently promotes transesterification, condensation (e.g., Claisen/Dieckmann/Knoevenagel), elimination, and selective deprotonation/alkylation steps with fast, clean kinetics. Supplied as a free-flowing solid or ethanolic solutions (e.g., 18–21% w/w or custom), it offers high basicity and excellent compatibility in ethanol systems. Each lot is controlled for assay, low moisture, and low carbonate, with COA/TDS available. Highly moisture-sensitive and caustic—protect from air/CO₂ and handle dry;
Product Description
Sodium Ethoxide (Sodium Ethylate) (Manufacturer: Shandong Yinglang Chemical Co., Ltd.)
Sodium ethoxide is a versatile alkoxide base widely applied in organic synthesis, biodiesel (ethyl ester) production, polymer modification, pharmaceuticals, and fine chemicals. As a strong base and efficient catalyst, it promotes transesterification, condensation (Claisen/Dieckmann/Knoevenagel), elimination, and selective deprotonation/alkylation, while serving as a convenient sodium source in alkoxide-mediated transformations and ligand preparation. Offered as free-flowing solids or ethanolic solutions (e.g., 18–21% w/w), it delivers high basicity, excellent ethanol compatibility, and fast, clean kinetics—making it an essential tool from lab development to continuous industrial production.
Sodium Ethoxide, also known as Sodium Ethylate, is a white to yellowish hygroscopic powder or a clear viscous solution dissolved in ethanol. As a strong organic base, it is widely used in organic synthesis for condensation, esterification, and polymerization reactions.At Shandong Yinglang Chemical, we are a specialized Sodium Ethoxide Manufacturer. We provide two main grades to meet diverse industrial needs:
- Solid Sodium Ethoxide (99% Powder)
- Liquid Sodium Ethoxide (18% – 21% Ethanol Solution)
Our advanced production process ensures low free alkali content and high reactivity, making it the preferred choice for pharmaceutical and pesticide industries.
