Description

2-Ethoxy-3-Methylpyrazine is a high-purity alkylated pyrazine compound, a key building block and flavor/aroma agent. It matters for its ability to impart characteristic nutty, roasted, and earthy notes, which are essential for creating authentic and complex sensory profiles. This product is needed by flavor and fragrance houses, food and beverage manufacturers, and research institutions focused on synthetic chemistry and sensory science.

Application

• Flavor & Fragrance Industry: A primary aroma chemical used to create and enhance nutty, roasted coffee, cocoa, and peanut nuances in food, beverages, and savory applications.
• Food & Beverage Manufacturing: Incorporated into flavor systems for snacks, confectionery, dairy products, and alcoholic/non-alcoholic beverages to achieve authentic roasted character.
• Synthetic Chemistry: Serves as a versatile intermediate or starting material in organic synthesis for pharmaceuticals, agrochemicals, and other fine chemicals.
• Research & Development: Used in academic and industrial R&D for studying structure-odor relationships, developing new flavor compounds, and chemical process optimization.
• Cosmetics & Personal Care: Employed in trace amounts to contribute to the overall scent profile of premium cosmetic formulations and personal care products.

Quality Control

Our 2-Ethoxy-3-Methylpyrazine is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards, including FEMA and FCC guidelines for flavor ingredients. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, guaranteeing consistency and reliability for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled 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) after opening to maintain purity and prevent degradation. Keep away from heat, sparks, and open flame.
