1,3-diphenyl-2-propanone

1,3-diphenyl-2-propanone (CAS Number: 102-04-5) is an organic chemical compound belonging to the class of aromatic ketones. Its molecular structure consists of a three-carbon chain with two phenyl groups attached at the terminal positions. In the context of food additives, it functions as a flavoring agent or flavoring adjuvant—substances that contribute taste or aroma to food products.

As a flavoring agent, 1,3-diphenyl-2-propanone is used in very small quantities to enhance the sensory properties of food and beverages. Like other flavor compounds, it would typically be added in trace amounts where its aromatic profile contributes to the desired taste or smell of a final product. However, specific commercial applications and product categories utilizing this additive are limited in publicly available data.

According to FDA records, there have been zero reported adverse events associated with 1,3-diphenyl-2-propanone consumption, and no product recalls have been issued related to this substance. This lack of reported incidents suggests no acute safety concerns have emerged from its use in food applications.

The absence of adverse event reports does not constitute a formal safety determination. The chemical has not undergone the rigorous safety assessment required for GRAS (Generally Recognized as Safe) status, which involves extensive toxicological testing, literature review, and expert panel evaluation. Safety data specific to food use applications would typically include acute toxicity studies, sub-chronic and chronic toxicity assessments, genotoxicity testing, and reproductive/developmental toxicity studies.

1,3-diphenyl-2-propanone is not listed on the FDA's GRAS inventory. This means it has not been formally affirmed or determined to be generally recognized as safe for its intended use in food. For a flavoring agent to achieve GRAS status, manufacturers typically submit a GRAS notification to the FDA based on scientific evidence demonstrating safe use at intended levels.

The regulatory pathway for flavoring agents in the United States involves either GRAS notification or formal food additive petition processes. Without GRAS status, use of this compound in food would require either a completed food additive petition with FDA approval or operation under an existing food additive regulation.

International regulatory approaches vary. The European Union's scientific committees evaluate food flavoring substances through their own processes, with listings maintained in the EU flavoring database. Regulatory status should be verified for specific jurisdictions where products containing this additive may be marketed.

Publicly available peer-reviewed literature specifically evaluating 1,3-diphenyl-2-propanone for food safety applications is limited. Most chemical safety data for this compound derives from industrial or synthetic chemistry contexts rather than food additive evaluation.

For compounds seeking or requiring food additive approval, the FDA typically requires submission of comprehensive toxicological data packages. Such studies would assess the substance's behavior in the gastrointestinal tract, absorption, metabolism, excretion, and potential accumulation in tissues.

Manufacturers or interested parties seeking to use this additive in food would need to generate or compile appropriate safety data and submit it through the proper FDA regulatory channels. The absence of GRAS status indicates this formal assessment process has not been completed for food applications.
