Stability
Undecadienal is generally non-reactive under typical storage and handling conditions, requiring a cool, well-ventilated environment. While direct pH stability for this specific compound is not detailed, related undecadienals demonstrate good stability in neutral formulations such as body lotions and soaps, but show poor stability under highly acidic or alkaline conditions.
Conflicts

Safety
Safety Profile
Undecadienal is recognized by the FDA as a flavoring agent for food products. However, it is explicitly classified as a skin irritant (R38 'Irritating to skin' and GHS hazard statement H315 'Causes skin irritation') based on 94.4% of reports in the ECHA C&L Inventory. The International Fragrance Association (IFRA) strongly advises that 2,4-undecadienal 'should not be used as a fragrance ingredient' due to significant safety concerns.
