What is 4-methyl-cis-2-pentene?
4-methyl-cis-2-pentene (CAS Number: 691-38-3) is a colorless to pale yellow liquid organic compound belonging to the class of alkenes or olefins. It is characterized by a branched five-carbon backbone with a double bond in the cis configuration. In the food industry, this compound functions as a synthetic flavoring agent, contributing aromatic and taste properties to finished food products.
The compound's chemical structure gives it distinct volatility properties, making it suitable for applications where flavor compounds need to be dispersed throughout food matrices or released during consumption. Its use falls under the broader category of flavor compounds that are either naturally derived or synthetically produced.
Common Uses
4-methyl-cis-2-pentene is utilized in the flavor industry as a component of complex flavor formulations. It may be found in applications including:
- Beverage flavoring systems
- Confectionery and candy flavoring
- Dairy product flavoring
- Baked goods and grain-based products
- Snack food flavoring
The compound typically appears in proprietary flavor blends rather than as a standalone additive, where it contributes to the overall sensory profile of the finished food product. Its use levels are generally very low, consistent with typical flavor compound applications in food manufacturing.
Safety Assessment
The safety profile of 4-methyl-cis-2-pentene remains characterized by limited but existing data. The compound has generated zero reported adverse events in FDA monitoring systems and appears in no FDA recall records, indicating no documented safety incidents associated with its use in food applications.
As a volatile organic compound used in flavoring, the compound's safety evaluation considers factors including:
- Volatility and inhalation exposure potential
- Dermal absorption characteristics
- Oral bioavailability and metabolism
- Typical consumption exposure levels in food products
The absence of adverse event reports and recalls suggests that current usage levels have not raised safety concerns in the U.S. food supply. However, the lack of extensive published toxicological literature means that comprehensive hazard assessment data remains limited in the public domain.
Regulatory Status
4-methyl-cis-2-pentene does not hold FDA GRAS (Generally Recognized as Safe) status. This designation indicates that the compound has not undergone the formal GRAS affirmation process through the FDA.
Despite lacking GRAS status, the compound may be used in food products under FDA regulations governing food additives, though this requires appropriate regulatory authorization. Manufacturers using this ingredient should maintain compliance with applicable regulations and may need to reference specific FDA approvals or petitions related to its use.
International regulatory approaches may differ. Some regulatory jurisdictions may have different approval statuses or usage restrictions, and food manufacturers exporting products should verify compliance with destination country requirements.
Key Studies
Published scientific literature specifically addressing 4-methyl-cis-2-pentene remains limited. Most available information derives from:
- FDA flavor ingredient databases and regulatory files
- Chemical safety data sheets and property databases
- General toxicology principles applicable to structurally related compounds
- Industry-sponsored safety assessments conducted during product development
The absence of significant published research does not necessarily indicate safety concerns, as many flavor compounds in commercial use have similarly limited peer-reviewed literature. The zero adverse event and recall history suggests adequate safety margins in current applications.
Any prospective safety evaluations or additional toxicological research would typically be conducted as part of manufacturer due diligence or regulatory compliance processes rather than published as independent academic studies.
