What is 1-(p-methoxyphenyl)-2-propanone?
1-(p-methoxyphenyl)-2-propanone, also known by its CAS number 122-84-9, is an organic chemical compound belonging to the phenylpropanone class of molecules. It consists of a methoxyphenyl group attached to a propanone backbone, creating a compound with aromatic and aliphatic characteristics. The compound is a colorless to pale yellow liquid with a distinct aromatic odor profile.
Common Uses
This compound is employed primarily as a flavoring agent and flavoring adjuvant in the food industry. Flavoring agents are used in very small quantities to enhance or modify the taste and aroma profiles of food and beverage products. Like other synthetic flavoring compounds, 1-(p-methoxyphenyl)-2-propanone would typically be used at parts-per-million (ppm) levels in finished food products. Its specific organoleptic properties make it valuable for creating particular flavor notes in formulated foods, though detailed information about its current commercial applications is limited in public databases.
Safety Assessment
According to FDA records, there have been zero adverse events reported and zero recalls associated with this additive. However, the absence of reported adverse events does not automatically establish safety, as underreporting and limited surveillance data are common in food additive monitoring systems.
The compound has not received GRAS (Generally Recognized as Safe) status from the FDA, which means it has not been formally affirmed as safe for consumption by qualified experts based on published scientific evidence. This distinction is important: GRAS status requires either substantial consensus among qualified scientific experts or pre-market approval data demonstrating safety at intended use levels.
Toxicological data on this specific compound appears limited in publicly accessible scientific literature. Standard safety evaluations for flavoring agents typically include acute toxicity studies, repeat-dose toxicity studies, genotoxicity assessments, and developmental/reproductive toxicity studies. Without clear documentation of comprehensive safety studies for this particular compound, its toxicological profile remains incompletely characterized in the public domain.
Regulatory Status
In the United States, 1-(p-methoxyphenyl)-2-propanone is not listed among FDA-approved food additives or GRAS substances. This means it cannot be legally added to food products intended for sale in the U.S. market without specific regulatory approval.
The regulatory status in other jurisdictions, including the European Union, Japan, and other countries, varies. The European Commission's food additives database and EFSA (European Food Safety Authority) evaluations should be consulted for EU authorization status. Some compounds in this chemical class may have authorization in certain regions based on different regulatory frameworks and risk assessment conclusions.
The lack of FDA GRAS status suggests either that: (1) the compound has not been submitted for GRAS affirmation, (2) it was submitted but not accepted, or (3) it is being used under a food additive petition process if applicable.
Key Studies
Public scientific literature on the safety of 1-(p-methoxyphenyl)-2-propanone is sparse. Comprehensive toxicological studies, if conducted, may not be publicly available or may exist only in regulatory dossiers held by manufacturers or regulatory agencies.
For comparison, safety evaluations of structurally similar phenylpropanone-based flavoring compounds have been conducted by international bodies such as the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the EFSA's Panel on Food Additives and Nutrient Sources. These evaluations typically examine metabolic pathways, potential genotoxicity, and systemic toxicity endpoints.
Researchers and consumers seeking detailed safety information on this compound should consult the FDA's Color Additives Status List, the Flavoring Ingredients Database, or contact manufacturers directly for toxicological data. Professional toxicology databases and peer-reviewed literature may provide additional chemical characterization and preliminary safety data.
