What it is Filled
Oxetene is an unsaturated four-membered oxygen heterocycle with molecular formula C3H4O, containing one oxygen atom, three carbon atoms and one carbon-carbon double bond in the ring.
In scope
- Parent oxetene identity and structure-linked identifiers
- Evidence distinguishing oxetene from isomers and substituted oxetenes
- Sample purity, concentration, medium and preparation history
- Physical properties and persistence under explicitly recorded conditions
- Evidence supporting handling, characterization and transformation decisions
Out of scope
- Substituted oxetenes as independently identified substances
- Oxetane and other neighbouring heterocycles
- Complete synthesis procedures and reaction apparatus
- Commercial formulations containing oxetene
- Facility-wide chemical safety and waste-management systems
Why it exists Filled
Enable an agent to identify oxetene, assess evidence for its presence and condition, and determine which characterization, handling or transformation decisions are supported.
Distinguishing features Filled
- The proposed identity has a four-membered ring containing three carbon atoms and one oxygen atom, with one endocyclic carbon-carbon double bond; the recorded SMILES is C1C=CO1. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/2H-oxete)
- Its molecular formula is C3H4O; identification must establish connectivity because formula alone cannot distinguish constitutional isomers. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/2H-oxete)
- Oxetane is the saturated neighbour with formula C3H6O, so an oxetane record cannot supply oxetene's identity or properties. [NIST](https://webbook.nist.gov/cgi/cbook.cgi?Name=OXETANE&Units=SI)
- The entry denotes the unsubstituted parent: evidence about a substituted oxetene must identify the substituents before it can be judged relevant.
What robots and AI may and may not do Filled
Must not
- Confuse oxetene with oxetane in orders, records or safety data.
- Present predicted properties as measured ones.
- Handle samples outside a controlled laboratory.
Only with a human decision
- Publishing new claims about its isolation or stability.
May
- Describe oxetene's structure and its reported reactivity, citing sources.
- Distinguish it from the saturated ring oxetane in records.
Moral aspects Filled
- Name confusion between related ring compounds causes safety and research errors.
Who is affected
- Researchers
- Laboratory staff
Owners Filled

Nobody owns the compound; laboratories answer for any samples they hold.
