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

5 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

0.001 ppb

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

Threshold	Matrix	Source	Paper
0.001 ppb SIDA	water	Rychlik 1998 · 2 studies	—

Retronasal / in-mouth

0.005 ppb – 3.7 ppb

Tasted rather than smelled — a different sense, not comparable.

Other matrix

0.175 ppb – 11.2 ppb

Measured in a non-aqueous medium (oil, starch, cellulose).
