It does not have a FEMA number as it is not typically used in flavor applications. The molecular formula for pivaloyl chloride is C5H9ClO, and it has a molecular weight of 120.58 g/mol. This compound is characterized by the presence of a carbonyl chloride functional group, which is reactive and contributes to its utility in chemical synthesis rather than direct sensory applications.\n\nCitation hooks: FlavScents; PubChem; FEMA" }, { "id": "sensory", "title": "Sensory Profile", "content": "Pivaloyl chloride is not commonly associated with a sensory profile in terms of odor or flavor, as it is primarily used as a reagent in chemical synthesis. Its reactivity and potential for hydrolysis make it unsuitable for direct sensory applications. Therefore, specific odor and flavor descriptors, as well as taste or odor thresholds, are not typically documented for this compound.\n\nCitation hooks: FlavScents; peer-reviewed sensory literature" }, { "id": "natural_occurrence", "title": "Natural Occurrence & Formation", "content": "Pivaloyl chloride is a synthetic compound and does not occur naturally. It is typically produced through the reaction of pivalic acid with thionyl chloride or phosphorus pentachloride. As a synthetic reagent, it does not have relevance to 'natural flavor' or 'natural fragrance' designations.\n\nCitation hooks: FlavScents; food chemistry literature; EFSA/JECFA monographs" }, { "id": "flavor_use", "title": "Use in Flavors", "content": "Pivaloyl chloride is not used in flavor applications due to its reactive nature and potential for hydrolysis. It is primarily utilized in the synthesis of other compounds rather than as a direct additive in food or beverages. Consequently, there are no typical use levels or ppm ranges documented for this compound in flavor systems.\n\nCitation hooks: FlavScents; FEMA GRAS documentation; formulation literature" }, { "id": "fragrance_use", "title": "Use in Fragrances", "content": "Similar to its use in flavors, pivaloyl chloride is not used directly in fragrance formulations. Its primary role is as an intermediate in the synthesis of other fragrance compounds. Due to its reactivity, it does not contribute directly to fragrance profiles or volatility characteristics.\n\nCitation hooks: FlavScents; IFRA; fragrance chemistry texts" }, { "id": "regulatory", "title": "Regulatory Status (Regional Overview)", "content": "Pivaloyl chloride is not typically regulated as a flavor or fragrance ingredient due to its primary use as a chemical intermediate. In the United States, it is not listed under FEMA GRAS. In the European Union, it is not included in the list of flavoring substances under Regulation (EC) No 1334/2008. Similarly, it is not recognized as a flavor or fragrance ingredient in the United Kingdom, Asia, or Latin America. Its use is more relevant to industrial chemical regulations.\n\nCitation hooks: FEMA; EFSA; national authority publications" }, { "id": "safety", "title": "Toxicology, Safety & Exposure Considerations", "content": "Pivaloyl chloride is a reactive compound that can pose safety risks primarily through inhalation and dermal exposure. It is corrosive and can cause irritation to the skin, eyes, and respiratory tract. Due to its reactivity, it is not used in food or fragrance applications, thus oral exposure is not a typical concern. Safety measures should focus on minimizing inhalation and dermal contact, particularly in occupational settings.\n\nCitation hooks: EFSA; FEMA; PubChem; toxicology literature" }, { "id": "insights", "title": "Practical Insights for Formulators", "content": "For formulators, pivaloyl chloride is valuable as a reagent in the synthesis of more complex molecules. Its reactivity requires careful handling and storage to prevent unwanted reactions. It is not typically used in direct formulations for flavors or fragrances, but rather as a building block in chemical synthesis.\n\nCitation hooks: FlavScents; industry practice" }, { "id": "confidence", "title": "Confidence & Data Quality Notes", "content": "The data on pivaloyl chloride is well-established in terms of its chemical properties and industrial applications. However, its lack of use in direct flavor or fragrance applications means there is limited sensory and regulatory data specific to these fields. Industry practices focus on its role as a synthetic intermediate.\n\nCitation hooks: FlavScents" }, { "id": "qa_check", "title": "QA Check", "content": "- All required sections 1-9 are present\n- 'Citation hooks:' line is present under each section\n- Flavor section includes ppm ranges (not applicable for this compound)\n- Toxicology section covers oral, dermal, inhalation\n- Regulatory section mentions US, EU, UK, Asia, Latin America\n- If complex natural material: includes section 5a (not applicable)\n\nCitation hooks: (internal)" } ] }

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
