What is 2-methylallyl Butyrate?
2-methylallyl butyrate is an organic ester with the Chemical Abstracts Service (CAS) number 7149-29-3. It is a volatile compound composed of butyric acid esterified with 2-methylallyl alcohol. This compound belongs to the class of synthetic flavoring substances and is used exclusively for its aromatic and flavor-enhancing properties in food manufacturing.
Common Uses
2-methylallyl butyrate is employed as a flavoring agent in the food and beverage industry. Due to its fruity and buttery sensory characteristics, it is typically used in small concentrations in products such as beverages, baked goods, confectionery, and processed foods. The compound is valued for its ability to contribute complex flavor profiles without substantially altering the organoleptic properties of finished products. Like other synthetic flavoring agents, it is used at levels determined by sensory evaluation and regulatory compliance rather than nutritional intent.
Safety Assessment
According to FDA records, there have been zero reported adverse events associated with 2-methylallyl butyrate and zero product recalls linked to this substance. The absence of reported incidents in the FDA database suggests no significant acute safety concerns have been documented through normal food supply surveillance. However, it is important to note that this additive is not currently listed on the FDA's Generally Recognized as Safe (GRAS) list, which means it has not undergone the formal GRAS notification process or been formally affirmed as safe by the agency.
The limited toxicological data available in scientific literature does not indicate significant hazards at typical use levels in food. As with most synthetic flavor compounds used at minimal concentrations, the primary safety consideration relates to the total dietary exposure across all food sources combined.
Regulatory Status
2-methylallyl butyrate does not hold FDA GRAS status, which distinguishes it from some other commonly used synthetic flavoring compounds. This indicates that while it may be used in food, it has not received the specific regulatory clearance that GRAS status provides. The compound's regulatory acceptance varies internationally; some regions may permit its use under different regulatory frameworks, while others may have specific restrictions or require pre-market approval.
Manufacturers using this flavoring agent are responsible for ensuring compliance with all applicable food safety regulations in their respective markets. In the United States, the use of flavoring agents is regulated under 21 CFR Part 182 and related sections of the Code of Federal Regulations.
Key Studies
Limited peer-reviewed literature specifically addresses 2-methylallyl butyrate as an isolated substance. Most safety information derives from its chemical classification as a butyrate ester and its use history in food flavoring applications. The broader class of short-chain fatty acid esters has been evaluated for safety, with butyrates generally recognized as compounds with minimal systemic toxicity at typical exposure levels.
General toxicological principles suggest that ester compounds of this type have relatively low bioavailability and undergo hydrolysis in the gastrointestinal tract. Butyric acid itself is a naturally occurring short-chain fatty acid present in dairy products and produced during normal colonic fermentation.
Further toxicological study and formalized GRAS evaluation could provide additional safety documentation. Researchers and manufacturers interested in this compound should consult with regulatory affairs specialists to determine appropriate testing and documentation requirements for their intended markets.
