  • Misspelling as 'stilbeen' or 'stylbene'.
  • Using it as a countable noun in the plural without a clear referent (e.g., 'three stilbenes' is ambiguous without specifying derivatives).

FAQ

Frequently Asked Questions

Stilbene itself is a synthetic compound, but many of its derivatives (like resveratrol) occur naturally in plants.

Its primary industrial use is in the manufacture of optical brighteners for paper and textiles, and as a precursor for certain dyes.

The trans isomer is more thermodynamically stable and is often the default structure referred to in synthesis and studies unless specified otherwise.

Indirectly, yes. You might encounter its derivatives as fluorescent whitening agents in laundry detergents or as the active compound resveratrol in dietary supplements.
