2,6-nonadienal Diethyl Acetal

2,6-nonadienal Diethyl Acetal (CAS Number: 106950-34-9) is a synthetic organic compound belonging to the acetal class of chemicals. It is derived from nonadienal, a nine-carbon aldehyde compound, modified through acetalization with diethyl groups. This chemical modification creates a stable flavoring molecule commonly used in the food industry to provide fruity, melon-like, and slightly floral aromatic notes to food and beverage products.

This flavoring agent is primarily used in the formulation of processed foods, beverages, and flavor blends where fruity taste profiles are desired. Common applications include flavored beverages, confectionery products, baked goods, and dairy-based products. The compound is typically used in very small concentrations (parts per million) to achieve the desired sensory effect. As a synthetic flavoring, it allows manufacturers to create consistent flavor profiles across multiple production batches and to achieve flavor combinations that may be difficult or expensive to obtain from natural sources alone.

According to FDA records, there have been zero adverse events reported related to 2,6-nonadienal Diethyl Acetal and zero product recalls involving this ingredient. The absence of reported adverse events suggests that the compound has not been associated with consumer health complaints or safety incidents in the United States market.

The compound has not received formal FDA GRAS (Generally Recognized as Safe) status, which means it has not undergone the specific GRAS notification process. However, this does not necessarily indicate a safety concern; rather, it reflects that the ingredient may be used under other regulatory frameworks, such as the FDA's Food Additive Petitions process or through other compliance mechanisms. Many flavoring compounds function in commerce without formal GRAS designation.

Toxicological data on this specific acetal is limited in published scientific literature available to the general public. Standard safety assessments for synthetic flavorings typically evaluate acute toxicity, chronic toxicity, genotoxicity, and reproductive effects through laboratory studies. The chemical structure—an acetal derivative—is a common functional group in approved flavoring substances, which generally have favorable safety profiles at food-use levels.

In the United States, 2,6-nonadienal Diethyl Acetal may be used as a flavoring agent under FDA regulations governing food additives. While not bearing GRAS status, it may be permitted under the authority of FDA's Food Additive Petition process or as a component of established flavoring mixtures. The lack of recalls and adverse event reports indicates compliance with regulatory requirements and safe use history in the American food supply.

Regulatory status in other jurisdictions, such as the European Union, may differ. The EU maintains its own approval processes for flavoring substances, and not all compounds approved in one region are necessarily approved in another. Consumers or manufacturers should verify compliance with local regulations in their specific country or region.

Published peer-reviewed research specifically examining the safety profile of 2,6-nonadienal Diethyl Acetal is not readily available in mainstream scientific databases. Safety assessments for synthetic flavorings are often conducted by manufacturers and submitted to regulatory agencies as confidential business information, limiting public access to detailed study reports.

The flavor industry relies on established protocols for evaluating new flavoring compounds, including guidelines from organizations such as the Flavor and Extract Manufacturers Association (FEMA). These assessments typically follow internationally recognized toxicological testing standards to ensure consumer safety.
