Description

Pyrazine, 3,5-Diethyl-2-Methyl- (8Ci,9Ci) is a specialized alkyl-substituted pyrazine derivative, a class of compounds renowned for their potent organoleptic properties. This compound matters for its ability to impart unique roasted, nutty, and earthy flavor notes, making it a critical ingredient in the creation of complex flavor and fragrance profiles. It is primarily needed by flavor and fragrance houses, food ingredient manufacturers, and research institutions focused on synthetic chemistry and sensory science. CAS NO 18138-05-1.

Application

• Flavor & Fragrance (F&F) Industry: A key building block for creating and enhancing savory, roasted, nutty, and meaty flavor profiles in processed foods, snacks, and savory applications.
• Food Ingredient Manufacturing: Used in the synthesis of reaction flavors and as a component in flavor formulations for soups, sauces, gravies, and ready-to-eat meals.
• Fragrance Compounds: Employed as a base note in fine fragrances and functional perfumery to add depth and earthy, tobacco-like nuances.
• Pharmaceutical Intermediates: Serves as a valuable heterocyclic intermediate in the research and synthesis of novel active pharmaceutical ingredients (APIs).
• Agrochemical Research: Utilized in the development of new crop protection agents and pesticides due to the pyrazine core's bioactivity.
• Chemical Synthesis: Acts as a versatile alkylated pyrazine precursor in organic synthesis and material science research.
