Lots of the data belongs to the unspecified material which is used as a biocide. I don't think the structure should have any geometry and is in reality 23621565

Thank you for your feedback. Quaternium-15 is now an approved synonym on record 23621565, so both records should show up in a search. Since both records have a fair amount of data against them, I am leaving both in place for the moment.
