Description

Filbertone,5-Methyl-(E)-2-Hepten-4-One is a high-purity, unsaturated ketone known for its characteristic nutty, roasted hazelnut aroma. This compound is a key flavor and fragrance ingredient prized for its potent organoleptic properties and clean sensory profile. It is essential for flavorists and perfumers seeking to create authentic, sophisticated nutty notes in premium applications.

Application

• Flavor & Fragrance (F&F) Industry: A primary building block for creating and enhancing nutty, roasted, and creamy flavor profiles in food, beverages, and confectionery.
• Perfumery: Used as a heart note in fine fragrances, colognes, and personal care products to impart warm, gourmand, and woody nuances.
• Food & Beverage: Formulation of flavors for baked goods, dairy products (ice cream, yogurt), chocolate, coffee, and nut-based spreads.
• Aroma Chemicals: Serves as a valuable intermediate or reference standard in the synthesis and quality control of other aroma compounds.
• Research & Development: Utilized in academic and industrial R&D for olfactory studies, sensory science, and the development of novel flavor systems.

Quality Control

Our Filbertone is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Every lot is analyzed using advanced chromatographic and spectroscopic techniques to confirm identity, strength, and purity. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, isomer ratio, and impurity profile is provided with each shipment, ensuring compliance with FEMA, FCC, and IOFI guidelines for flavor ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile nature, keep containers tightly sealed when not in use to prevent evaporation and maintain product integrity. Keep away from heat, sparks, and open flame.
