Can 2-Thienylmethanol be labeled natural?

Since 2-Thienylmethanol is found in nature, US labeling follows how it was obtained: natural flavor from a natural source and a natural process, artificial when 2-Thienylmethanol is synthesized. The EU and UK follow the same logic without a middle class; Mercosur and Mexico label synthetic 2-Thienylmethanol identical-to-natural.

How each market defines the classes: natural vs artificial flavor under 21 CFR 101.22.

Regulatory status, with citations

United States

2-Thienylmethanol is FEMA GRAS under FEMA number 4642. It is cited in the Code of Federal Regulations at 21 CFR 172.515.

21 CFR 172.515

European Union and United Kingdom

No EU FL number is on file for 2-Thienylmethanol. 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.

JECFA (WHO / FAO)

JECFA number 2111, evaluated at the 86th meeting in 2018. No safety concern at current levels of intake.

Sources and attribution. The identity and regulatory facts on this page are taken from the FDA Substances Added to Food inventory, a US government record, which lists this substance as 2-THIENYLMETHANOL under CAS 636-72-6 and carries its FEMA number, its JECFA flavor number. The inventory is searchable at FDA. FDA records its technical effect as flavoring agent or adjuvant.

A FEMA GRAS conclusion is reached by the Expert Panel of the Flavor and Extract Manufacturers Association of the United States, and the FEMA number names that conclusion. FEMA publishes its own entry for this substance in the FEMA Flavor Library, which is the authoritative record of what the Panel decided and is worth reading alongside this page.
