Description

2-Ethoxy-3-Isopropylpyrazine is a high-purity pyrazine derivative valued for its potent organoleptic properties. This compound is a key ingredient for imparting and enhancing specific roasted, nutty, or earthy flavor and aroma profiles in advanced formulations. It is essential for flavor and fragrance chemists, as well as research scientists, seeking to develop sophisticated sensory experiences. Primary demand originates from the flavor & fragrance, food technology, and fine chemical synthesis industries.

Application

• Flavor & Fragrance (F&F) Industry: A key aroma chemical for creating and modulating roasted, nutty, coffee-like, or earthy notes in savory flavors, snack seasonings, and premium fragrances.
• Food Technology: Used as a flavor enhancer in processed foods, meat analogs, sauces, and ready-to-eat meals to replicate authentic cooked flavors.
• Beverage Flavors: Employed in the formulation of coffee, cocoa, and malt-based beverages to intensify desirable roasted characteristics.
• Fine Chemical Synthesis: Serves as a versatile building block or intermediate for synthesizing more complex pyrazine derivatives for pharmaceutical or agrochemical research.
• Research & Development: Utilized in academic and industrial R&D settings for olfactory studies, sensory science, and the development of novel functional ingredients.

Quality Control

Our 2-Ethoxy-3-Isopropylpyrazine is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity suitable for flavor and fragrance applications. Quality assurance includes rigorous analytical testing via GC, GC-MS, and NMR. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific impurity profiles is provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider keeping under an inert atmosphere (e.g., nitrogen) to preserve stability and prevent degradation. Keep away from strong oxidizing agents.
