1-(2-hydroxyphenyl)-3-(pyridin-4-yl)propan-1-one

1-(2-hydroxyphenyl)-3-(pyridin-4-yl)propan-1-one is a synthetic organic compound classified as a flavoring agent. The molecule contains a hydroxyphenyl group (derived from phenol) and a pyridin-4-yl moiety (derived from pyridine, a nitrogen-containing aromatic ring). This specific chemical structure (CAS number 1186004-10-3) is designed to provide or enhance flavor characteristics in food and beverage applications.

This compound functions as a flavoring agent or flavoring adjuvant in the food industry. Flavoring adjuvants are substances that contribute to the overall flavor profile of food products, either by providing direct flavor notes or by modifying and enhancing existing flavors. Such synthetic flavoring compounds are typically used in very small quantities—often measured in parts per million (ppm)—in beverages, confections, baked goods, dairy products, and other processed foods.

The specific organoleptic properties (taste and aroma characteristics) of this compound determine its applications within food formulations.

As of current records, there have been zero adverse events reported to the FDA associated with this additive, and zero recalls have been issued related to its use. This suggests no significant safety incidents in the food supply have been documented.

However, it is important to note that this compound has not been designated as Generally Recognized as Safe (GRAS) by the FDA. GRAS status requires either a long history of safe use in food before 1958 or approval through the GRAS notification process. The absence of GRAS status does not necessarily indicate the substance is unsafe; rather, it means it has not undergone the formal FDA review process for this designation.

Synthetic flavoring compounds typically undergo safety evaluation by flavor and fragrance industry bodies such as the Research Institute for Fragrance Materials (RIFM) or through formal FDA petition processes. The limited quantity used in food applications and the chemical structure's similarity to other approved flavoring compounds suggest general safety potential, though specific toxicological data would be needed for definitive conclusions.

In the United States, flavoring compounds can be used in food under 21 CFR Part 182 (Substances Generally Recognized as Safe) or 21 CFR Part 184 (Direct Food Substances Affirmed as GRAS), provided they meet specific use levels and purity requirements. Additionally, many synthetic flavors are used under the FDA's indirect approval pathway through industry-conducted safety assessments or formal food additive petitions.

Without GRAS status, this specific compound would require either a food additive petition approval or demonstration of safety through the GRAS notification process prior to commercial food use in the United States. International regulatory status may vary—the European Union, Canada, and other countries maintain separate approval processes for flavoring substances.

Given the chemical structure and intended use as a minor flavoring component, any safety assessment would typically include standard toxicological evaluations covering acute toxicity, subchronic toxicity, and genotoxicity. Such studies are generally conducted by flavor manufacturers or research organizations before commercial introduction.

The absence of recorded adverse events and recalls in FDA databases suggests either limited current use in the food supply or a safe use history at typical consumption levels. Comprehensive safety data would be expected in FDA submissions or published flavor safety literature if this compound is actively used in commercially available products.

Consumers seeking information about specific products containing this flavoring should review product labels and contact manufacturers directly, as flavoring compounds are often listed generically as "natural" or "artificial flavors" rather than by chemical name.
