Description

Pyrazine, 2,5-Dimethyl-3-(2-Methylbutyl)- (9Ci) is a specialized alkyl-substituted pyrazine derivative, a class of compounds renowned for their potent organoleptic properties. This compound is valued for its ability to impart complex, nutty, roasted, and earthy flavor and aroma notes, making it a critical ingredient in high-value flavor and fragrance formulations. It is primarily sought after by flavorists and perfumers in the food & beverage, fragrance, and fine chemical synthesis industries seeking to create sophisticated sensory profiles.

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.
• Perfumery: Used as a fragrance ingredient to add earthy, green, and woody nuances to fine fragrances, personal care products, and household detergents.
• Food Additive Manufacturing: Serves as a precursor or direct additive in the production of reaction flavors (e.g., meat, cocoa, coffee flavors) through Maillard reaction processes.
• Chemical Synthesis: Acts as a versatile intermediate in organic synthesis for pharmaceuticals, agrochemicals, and other specialty chemicals due to its reactive pyrazine core.
• Research & Development: Utilized in academic and industrial R&D for studying structure-odor relationships and developing new flavoring agents.

Quality Control

Our Pyrazine, 2,5-Dimethyl-3-(2-Methylbutyl)- (9Ci) is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and organoleptic quality, suitable for flavor and fragrance applications. A comprehensive Certificate of Analysis (COA) detailing purity (typically by GC), specific gravity, refractive index, and sensory evaluation is provided with every shipment to guarantee consistency and traceability.

Storage

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