European Union and United Kingdom
No EU FL number is on file for 5-Methyl-2-(methylthiomethyl)-2-hexenal. That is not a finding either way. The Union List covers defined flavouring substances, so natural complex materials are handled as flavouring preparations under Parts B to F and never receive a number, and substances used as additives sit under Regulation 1333/2008 instead. Confirm the position before EU or UK use.
