Reason for deprecation: Deprecate record: looks very strained and suspect this is mis-representation of carene

If you believe this record was deprecated in error, please use the Comment on this record button to contact the ChemSpider team.

Common reasons for deprecation are:
  • Chemically impossible structures (eg. incorrect valence atoms)
  • Lack of any linking data sources
  • Poor depiction of a structure that is already in ChemSpider
