A rare or archaic chemical compound or alternative nomenclature term, possibly related to fluorine-containing organic compounds.
Likely from fluorine + -indin or -indine (chemical nomenclature suffix). This appears to be an obsolete or highly specialized chemical term with unclear current usage.
Historical chemistry had many naming conventions that are no longer used—this term likely comes from an era when chemists hadn't standardized how to name complex fluorine compounds, before IUPAC (the international naming system) was established.
