EPA lists this substance on the non-confidential Toxic Substances Control Act Chemical Substance Inventory as Benzene, [2-[(2-methyl-1-undecen-1-yl)oxy]ethyl]-.

This is a TSCA industrial chemistry record, not a food or flavor assessment. Presence on the TSCA Inventory says a substance is in US commerce. It says nothing about whether it may be used in food, and this substance is not FEMA GRAS. For flavor ingredients see the FEMA GRAS lookup.

Commercial activity status

Active

EPA designates this substance active in US commerce, so no Notice of Activity Form B is required before manufacturing. What active and inactive mean.

EPA regulatory flags

EPA marks this listing with 3 flags. Each one is shown with EPA's own definition and what it obliges.

PMN Commenced PMN substance

Indicates a commenced PMN substance.

What it obliges: Nothing new. The substance already went through premanufacture review and someone filed a notice of commencement, which is why it is on the Inventory. It is an existing chemical and needs no new premanufacture notice.

What it does not establish: The flag records how the substance arrived, not what may be done with it. Check the flags beside it.

SP Proposed Significant New Use Rule

Indicates a substance that is identified in a proposed Significant New Use Rule.

What it obliges: No significant new use notice yet. Export notification under TSCA section 12(b) already applies, because 40 CFR 721.20 reaches substances named in a proposed rule as well as a final one.

What it does not establish: A proposed rule may change or may never be finalized. Read the proposal.

5E TSCA section 5(e) order

Indicates a substance that is the subject of a TSCA section 5(e) order.

What it obliges: Compliance with the order, which sets terms for how the substance may be manufactured, processed or used. Orders commonly follow premanufacture review, which is why this flag usually sits beside PMN.

What it does not establish: The terms of the order are not published on the Inventory. This flag records that one exists, not what it says.

What this page does not establish

It reports what EPA publishes about CAS 2489743-82-8 in the July 2026 release of the non-confidential Inventory. It does not report the contents of any order or rule that a flag points at, because EPA does not publish those on the Inventory, and it does not say whether a particular use of yours is permitted.

It is also not a food or flavor clearance. This substance carries no FEMA GRAS number.
