Description

2,3-Dimethyl-5-Ethylpyrazine is a heterocyclic organic compound belonging to the alkylpyrazine class, known for its potent, nutty, and roasted aroma profile. This compound is a high-value flavor and fragrance ingredient prized for its ability to impart authentic roasted, coffee, and cocoa notes at low concentrations. It is essential for manufacturers in the flavor and fragrance (F&F) industry, as well as for research and development in food science and synthetic chemistry.

Application

• Flavor & Fragrance Formulation: A key aroma chemical used to create and enhance savory, roasted, nutty, coffee, and chocolate flavor profiles in processed foods, snacks, and beverages.
• Food & Beverage Industry: Employed as a flavoring agent in savory applications, including meat analogs, soups, sauces, and ready-to-eat meals.
• Perfumery: Used in fragrance compositions to add warm, roasted, or tobacco-like nuances to fine fragrances and personal care products.
• Synthetic Intermediate: Serves as a valuable building block in organic synthesis for the preparation of more complex heterocyclic compounds in pharmaceutical and agrochemical research.
• Aroma Standard & Reference Material: Utilized in analytical laboratories for gas chromatography (GC) and mass spectrometry (MS) as a reference standard for quality control and flavor analysis.

Quality Control

Our 2,3-Dimethyl-5-Ethylpyrazine is produced and tested to meet the stringent requirements of the flavor and fragrance industry. Quality is assured through rigorous analytical controls including Gas Chromatography (GC) and GC-Mass Spectrometry (GC-MS) to ensure purity and olfactory profile consistency. A Certificate of Analysis (COA) is provided with each batch, detailing specifications for identity, purity, and organoleptic properties. Our quality management system supports compliance with relevant standards, including FEMA GRAS and IOFI guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat and ignition sources. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
