Origins and Meanings of Fumaric Acid Names

Scientific Naming

Scientists follow rules to name chemicals. The name fumaric acid comes from “Fumāria.” This is a plant called fumitory. Fumitory has fumaric acid in it. Fumaric acid has two carboxyl (COOH) groups. These groups are on opposite sides of an ethylene chain. This shape makes it a geometric isomer of maleic acid.

  • “2-Butenedioic acid” tells us about the molecule’s backbone. It means there is a double bond and two acid groups.
  • “Trans-1,2-Ethylenedicarboxylic acid” shows the trans form. The acid groups are across from each other.
  • “Trans-Butenedioic acid” and “(E)-2-Butenedioic acid” also mean the acid groups are across from each other.

Fumaric acid is a butenedioic acid. This is important because it shares a structure with maleic acid. Scientists use this to guess how fumaric acid acts in reactions and products.

Note: The CAS number for fumaric acid is special. It helps scientists find it in databases.

CompoundCAS NumberDescription
Fumaric Acid110-17-8A special code used in science lists to identify the compound.

Industry Naming

In industry, people use different names for fumaric acid. The name depends on how it is used. Food makers call it E297 or INS No. 297. These codes help companies and regulators track food additives. Fumaric acid is in fruit juices, gelatin desserts, tortillas, and pie fillings. It gives a fruity taste and keeps food fresh. The FDA says fumaric acid is safe to use.

  • Fumaric acid is made by changing maleic acid. This is done by a process called catalytic isomerization.
  • Other names like allomaleic acid, boletic acid, donitic acid, and lichenic acid come from nature or old naming systems.

Fumaric acid is important in science and industry. Its many names help people know how it is used and what it does.
