Not in FEMA GRAS publications 1-33. Of 3,367 listed flavoring substances, none match this compound name. May still be food-safe under other regulatory routes (FDA 21 CFR 172, EFSA, JECFA) — check femaflavor.org for the authoritative current list.

Published thresholds

11 measured values from the literature. Grouped by what was actually measured — a threshold smelled in clean water, tasted in the mouth, or measured in a real food are three different quantities and are not pooled.

Orthonasal, in clean water

140 ppb

The reference measurement — smelled in water. OAV is computed against this.

In a food matrix

0.580 ppb – 89.0 ppb

Measured in a real food, where the matrix shifts detection — not a clean-water value.
