itaconic acid
Very Low Frequency (Specialist/Scientific)Technical/Scientific
Definition
Meaning
A white crystalline organic acid with the chemical formula C5H6O4, produced industrially by fermentation of carbohydrates.
It is a dicarboxylic acid used primarily as a co-monomer in the production of specialty polymers, resins, plastics, and synthetic rubbers, valued for its ability to introduce cross-linking and improve properties like adhesion and water resistance.
Linguistics
Semantic Notes
The name originates from anagrammatic rearrangement of 'aconitic acid', from which it was first derived. It is a metabolite in certain fungal fermentation processes.

Learning
Memory Aids
Mnemonic
Think: 'I Take A CONcrete' mix – itaconic acid is used to modify polymers, which can be part of concrete additives.
Conceptual Metaphor
A BUILDING BLOCK or MODIFIER (it modifies polymer chains, adding functionality).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'иконная кислота' (nonexistent). The standard Russian term is 'итаконовая кислота'.
Common Mistakes
- Misspelling as 'itaconnic acid' or 'itaconicacid' (should be two words with 'acid').
- Mispronouncing the stress (stress is on the third syllable: i-ta-CON-ic).

FAQ
Frequently Asked Questions
It is a naturally occurring organic acid produced by certain fungi (e.g., Aspergillus terreus), but it is also produced synthetically on an industrial scale via fermentation of carbohydrates like glucose.
It is used primarily in the polymer and plastics industry to make synthetic resins, latex, adhesives, and superabsorbent polymers. It also finds use in detergents and as a building block for other specialty chemicals.
It is considered a promising biobased platform chemical because it can be produced renewably from sugar fermentation, offering a sustainable alternative to petrochemical-derived monomers like acrylic acid in some applications.
The standard pronunciation places the primary stress on the third syllable: i-ta-CON-ic (/ˌɪtəˈkɒnɪk/ in British English, /ˌɪtəˈkɑːnɪk/ in American English).
