Molecular identity Resolve penguinone to a specific substituted cyclohexadienone.
Connectivity
Define the ring, carbonyl, double bonds and methyl positions.
Registered molecular graph
The identity anchor is a six-membered dienone ring with methyl groups at 3, 4, 4 and 5. The supplied SMILES and InChIKey are recorded by [NCATS](https://drugs.ncats.io/substance/JZ985K46ZX).

- Is the candidate a different positional isomer despite having formula C10H14O? boundary

Keep external identifiers attached to a verified graph, and distinguish an identifier assignment from authorization for any use.

Sample authentication Establish whether material actually contains the registered dienone at the claimed assay.
Structural evidence
Assess analytical support for the methyl substitution and dienone functionality.
Orthogonal identification

Physical behavior Characterize penguinone as isolated material or as a solute under explicit conditions.
Phase and thermal properties
Connect observed phase and transitions to sample composition and pressure.
Measured phase boundaries
Require measured evidence for melting, boiling or decomposition instead of filling missing constants from analogy.
- What phase does authenticated penguinone exhibit at the stated temperature and pressure? measurement
- Do reported thermal events represent melting or vaporization, or chemical decomposition? boundary
Solution properties
Establish useful solvent-dependent properties without conflating dissolution with reaction.
Solubility and recovery
Record equilibrium solubility and evidence that dissolved material retains penguinone identity.
- What concentration dissolves in each tested solvent at a specified temperature? measurement
- Does analysis after dissolution and recovery confirm unchanged penguinone? measurement
Dienone reactivity Assess transformations and persistence of this particular methyl-substituted dienone.
Acid response
Examine acid-induced transformations without assuming a generic dienone-phenol rearrangement outcome.
Rearrangement evidence
Treat claims about rearrangement or resistance to rearrangement as experimental questions requiring conditions, analytical detection limits and product identification.
- What primary experiments establish penguinone's response to acid, including any tests with trifluoroacetic acid? provenance
- Under which acid concentration, solvent, temperature and duration was conversion measured or excluded? measurement
Other transformations and persistence
Distinguish demonstrated reactions from hypotheses based on the carbonyl and alkene groups.
Condition-specific fate
Record starting-material retention and identified products under tested chemical, thermal and illumination conditions.

Handling and regulatory evidence Tie decisions about penguinone to applicable hazard information and substance records.
Hazard characterization
Identify which hazard conclusions are supported for penguinone and which remain unknown.
Substance-specific hazard support
Separate measured endpoints, formal classifications and analog-based estimates, retaining the identity and composition of tested material.
- Which toxicological, irritation, flammability or environmental endpoints were measured on authenticated penguinone? provenance
- Which proposed handling actions require evidence beyond the currently available hazard record? action
Jurisdiction and use
Resolve applicable substance listings, classifications and restrictions.
Applicable regulatory record
Record jurisdiction, date and material scope for regulatory conclusions; an identity code alone does not establish approval, exemption or unrestricted use.
- Is there a verified EC number, inventory listing or GHS classification for this exact molecular identity in the relevant jurisdiction? provenance
- Do any verified exposure limits, transport requirements or use restrictions apply to the intended material and activity? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
Penguinone is 3,4,4,5-tetramethylcyclohexa-2,5-dien-1-one, a nonaromatic cyclic dienone with molecular formula C10H14O whose common name refers to the penguin-like appearance of its structural drawing.
In scope
- Molecular connectivity, systematic names and verified chemical identifiers
- Sample identity, purity and differentiation from related dienones
- Physical properties tied to phase, conditions and measurement provenance
- Experimentally supported reactivity and stability of the substituted dienone
- Substance-specific hazard evidence and jurisdictional identity
Out of scope
- Other tetramethylcyclohexadienone positional isomers
- Products or solvent formulations containing penguinone as complete commercial objects
- Synthesis equipment and manufacturing workflows
- Reaction products as independently characterized substances
- Penguins, naming anecdotes and molecular drawings as independent subjects
Why it exists Filled
Enable an agent to identify penguinone, assess the identity and condition of a sample, and determine which handling or experimental actions its evidence supports.
Distinguishing features Filled
- Require the 3,4,4,5-tetramethyl substitution pattern on cyclohexa-2,5-dien-1-one; a matching molecular formula alone cannot establish identity. Identity reference: [NCATS substance record](https://drugs.ncats.io/substance/JZ985K46ZX).
- Check for one carbonyl at position 1, double bonds at 2-3 and 5-6, and two methyl groups on carbon 4; these distinguish the registered connectivity from other methylated cyclic ketones.
- Match the molecular graph to SMILES CC1=CC(=O)C=C(C)C1(C)C or InChIKey RHIYIMQPIGYWEK-UHFFFAOYSA-N, rather than relying on a penguin-like drawing.
- Cross-check CAS 34014-87-4 and PubChem CID 12564106 against the structure; do not accept a supplier name without structural agreement.
