Description

2-Methylthio-3(5/6)-Methylpyrazine is a high-purity heterocyclic compound used as a key flavor and fragrance intermediate. It is valued for its potent, nutty, roasted, and meaty aroma profile, making it essential for creating complex savory flavorings. This compound is primarily sought by manufacturers in the food flavoring, fragrance, and specialty chemical synthesis industries.

Application

• Savory Flavor Creation: A critical building block for replicating roasted, meaty, and nutty notes in processed foods, snacks, soups, sauces, and savory seasonings.
• Fragrance Formulation: Used as a trace component in fine perfumery and functional fragrances to add roasted coffee, cocoa, or nutty nuances.
• Reaction Intermediate: Serves as a versatile precursor in the synthesis of more complex pyrazine derivatives for research and specialty applications.
• Food & Beverage Industry: Employed in the flavoring of meat analogs, ready-to-eat meals, and certain beverage types requiring roasted character.

Quality Control

Our 2-Methylthio-3(5/6)-Methylpyrazine is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing including GC, HPLC, and NMR to ensure identity, purity, and organoleptic profile consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. Our quality commitment aligns with standards relevant to flavor and fragrance ingredients, including FEMA and FCC guidelines.

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 and minimize headspace in partially used containers to preserve quality and prevent degradation.
