Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.
Wöhler obtained urea from cyanate-derived starting materials in 1828, demonstrating laboratory interconversion between substances then assigned to inorganic and organic domains.
No alternate terminology is currently authored for this record.
Concept type
Historical motivating synthesis
Historical qualification
The synthesis did not instantly refute vitalism or single-handedly found organic chemistry. Its later symbolic role exceeded its immediate reception, while its actual chemical result remained decisive evidence that urea required no organism for its preparation.
source: Historically motivated; target: Historically motivated by
Authored annotation
laboratory access to a biological product
Authored explanation
Wöhler’s result became one strand in the nineteenth-century erosion of a sharp synthetic boundary between living and nonliving chemistry; its immediate causal role should not be inflated.
How to interpret this relation type
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.
