What is 2,3 or 10-mercaptopinane?
2,3 or 10-mercaptopinane is a synthetic organic compound classified as a flavoring agent. The compound contains a thiol (mercapto) functional group attached to a pinane hydrocarbon skeleton. Pinane is a bicyclic monoterpene-derived structure, and the addition of the mercapto group creates a volatile sulfur-containing molecule that contributes specific aromatic properties. This additive is produced through chemical synthesis rather than extraction from natural sources.
Common Uses
2,3 or 10-mercaptopinane is used in the flavor and fragrance industry as a flavoring agent and flavoring adjuvant. Its primary application is in creating complex flavor profiles in processed foods and beverages. The compound contributes subtle, specific taste notes that enhance overall flavor complexity. Like other synthetic sulfur-containing flavor compounds, it is typically used in very small concentrations—measured in parts per million (ppm)—to achieve the desired sensory effect without creating overpowering or unpleasant flavors. It may be used in categories such as beverages, confectionery, baked goods, and other processed food products.
Safety Assessment
According to FDA records, 2,3 or 10-mercaptopinane has not been assigned Generally Recognized as Safe (GRAS) status. However, this does not automatically indicate safety concerns; many flavoring compounds operate without formal GRAS designation through other regulatory pathways. The FDA has recorded zero adverse events and zero recalls associated with this additive, suggesting no documented consumer safety incidents in the United States marketplace.
The lack of reported adverse events and recalls provides a preliminary safety indicator, though it should be noted that absence of reported events does not constitute comprehensive safety data. Like other synthetic flavor compounds used in minimal quantities, the safety profile would be influenced by factors such as:
- Concentration levels in final food products
- Frequency and duration of consumption
- Individual sensitivity variations
- Metabolic processing by the body
Sulfur-containing flavor compounds are generally recognized as metabolized efficiently by the body due to their volatile nature and minimal bioaccumulation potential.
Regulatory Status
2,3 or 10-mercaptopinane does not hold FDA GRAS status. In the United States, flavoring ingredients may be regulated under different frameworks depending on their use history, production method, and intended application. The compound's CAS number (977136-05-2) is registered in the Chemical Abstracts Service database, providing chemical identity verification.
The regulatory status varies internationally. Different countries and regulatory bodies—including the European Food Safety Authority (EFSA), which oversees food additives in EU member states—maintain separate approval processes and additive listings. Manufacturers and importers are responsible for ensuring compliance with regulations in their respective markets.
Key Studies
Public scientific literature on 2,3 or 10-mercaptopinane is limited, which is typical for specialized synthetic flavor compounds with narrow applications. Most toxicological and safety data for such compounds remains proprietary within the flavor industry or submitted through regulatory channels that are not publicly available.
For related synthetic sulfur-containing flavor compounds, safety evaluation generally focuses on acute toxicity, genotoxicity, and allergenicity potential. Manufacturers developing new flavoring agents typically conduct or commission safety studies that are submitted to regulatory agencies during approval processes.
The lack of reported adverse events in FDA monitoring systems suggests this compound has not raised safety flags in practical use, though comprehensive safety literature remains sparse. Consumers or professionals seeking detailed safety information should contact the manufacturer or regulatory agencies directly.
