Description

2-Methoxy-5-(2-Methylpropyl)Pyrazine is a high-purity alkyl methoxypyrazine compound, a key building block and flavor/fragrance ingredient prized for its potent organoleptic properties. Its primary commercial value lies in its ability to impart characteristic green, earthy, and bell pepper-like notes at very low concentrations. This makes it an essential component for flavorists and perfumers in the food & beverage, fragrance, and specialty chemical synthesis industries seeking to create or enhance complex natural profiles.

Application

• Flavor & Fragrance (F&F) Industry: A key aroma chemical used to create or enhance green, vegetal, earthy, and bell pepper notes in savory flavors, alcoholic beverages, and fine fragrances.
• Food & Beverage: Used in the formulation of processed foods, snacks, sauces, and seasonings to replicate the fresh taste of vegetables like green bell peppers and peas.
• Perfumery: Incorporated into fragrance compositions for men's colognes, feminine florals, and avant-garde scents to add naturalistic green and herbal accents.
• Synthetic Intermediate: Serves as a valuable precursor in the organic synthesis of more complex pyrazine derivatives for pharmaceutical and agrochemical research.
• Aroma Chemical Production: Used in the manufacturing of compounded aroma chemicals and specialty essence oils.

Quality Control

Our 2-Methoxy-5-(2-Methylpropyl)Pyrazine 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, relevant for flavor and fragrance applications. Certificates of Analysis (COA) detailing purity (typically by GC), specific gravity, refractive index, and sensory evaluation are available upon request.

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, ensure containers are securely sealed when not in use to prevent evaporation and maintain product integrity.
