Description

2,3-Heptanedione CAS NO 96-04-8 is a high-purity diketone compound valued for its potent, buttery-creamy aroma and flavor profile. This chemical is essential for creating authentic dairy and nutty notes in complex flavor and fragrance formulations. It is a critical ingredient for flavorists and perfumers in the food & beverage, fragrance, and cosmetic industries seeking to enhance product sensory characteristics.

Application

• Flavor & Fragrance (F&F) Industry: A key aroma chemical used as a building block for creating buttery, creamy, and nutty flavor notes in dairy products, baked goods, and confectionery.
• Food Additives: Employed in the synthesis of advanced flavoring agents and as a direct additive (where compliant) to impart rich, savory characteristics to processed foods and snacks.
• Perfumery: Used in fragrance compositions to add creamy, caramelic nuances to gourmand, oriental, and woody accords.
• Chemical Synthesis: Serves as a versatile intermediate or precursor in organic synthesis and pharmaceutical research due to its reactive diketone functionality.
• Research & Development: Utilized in analytical laboratories as a reference standard for chromatography and sensory science studies.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flames.
