furaldehyde
Very LowTechnical/Scientific
Definition
Meaning
A colourless liquid aldehyde, C4H3O-CHO, derived from furan, used in making resins and as a chemical intermediate.
Specifically, 2-furaldehyde, commonly known as furfural, which is an aromatic aldehyde obtained from plant material like corncobs and oat hulls. It is a key industrial solvent and precursor to other chemicals.
Linguistics
Semantic Notes
In common technical use, 'furaldehyde' is essentially synonymous with 'furfural'. It refers specifically to the 2-formyl derivative of furan. It is not used in general discourse.

Learning
Memory Aids
Mnemonic
Think: FURan + aldehyde = FURALDEHYDE. It's the aldehyde version of the furan ring.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'формальдегид' (formaldehyde). The Russian term is 'фурфурол' (furfural).
Common Mistakes
- Misspelling as 'furaldehyde' (missing 'd').
- Confusing it with the more common 'formaldehyde'.
- Using it in non-technical contexts.

FAQ
Frequently Asked Questions
Yes, in common technical usage, 'furaldehyde' (specifically 2-furaldehyde) and 'furfural' are synonymous. 'Furfural' is the more frequently used term.
Almost exclusively in scientific literature, patents, or technical documents related to organic chemistry, renewable chemicals, and resin manufacturing.
Yes, it is an irritant to skin, eyes, and respiratory system and is toxic if ingested. It requires careful handling in a laboratory or industrial setting.
Its primary uses are as a solvent in petroleum refining, a precursor to furan resins and plastics, and a starting material for the synthesis of other industrial chemicals.
