Disodium fumarate, CAS 17013-01-3

Disodium fumarate is a dicarboxylate salt of fumaric acid, an important intermediate of the citric acid cycle. Disodium fumarate exists as an odorless, white, crystalline, or granular powder that is soluble in water. Structurally, fumarate is the trans-isomer of symmetric, unsaturated dicarboxylic acid; the cis isomer is maleate. Fumarates are used as adhesion promoters for different substrates in the coating industries, metal-organic frameworks precursors, biomarkers, preservatives, feed additive, pH control agent and buffering agent in cosmetics. Other industrial uses of fumarate salts are in jet printing inks, plastics surface coating, paper sizing, and as an intermediate in the preparation of unsaturated polyester and alkyd resins. In pharma, disodium fumarate is used as a bleaching agent, precursor for ferrous fumarate and monoethyl fumarate. Sodium fumarate is utilized as a key biochemical intermediate.
