Description

2-(1-Methylethyl)-3-[(2-Methyl-3-Thienyl)Thio]Pyrazine is a specialized heterocyclic compound featuring a pyrazine core substituted with an isopropyl group and a thienylthio moiety. This unique structure makes it a valuable intermediate and flavor/fragrance ingredient, prized for its ability to impart complex, roasted, and savory notes. It is primarily needed by flavor and fragrance houses, food ingredient manufacturers, and fine chemical synthesis operations seeking to create sophisticated organoleptic profiles or advanced chemical entities.

Application

• Flavor and Fragrance Creation: A key building block for synthesizing complex savory, roasted, meaty, and nutty flavor compounds used in processed foods, snacks, and savory applications.
• Fragrance Formulation: Used as an intermediate in the production of aroma chemicals that contribute unique, sulfurous, or roasted nuances to fine fragrances and personal care products.
• Fine Chemical Synthesis: Serves as a versatile heterocyclic intermediate in pharmaceutical research and the synthesis of agrochemicals or other specialty organic compounds.
• Food Ingredient Manufacturing: Incorporated into reaction flavors and process flavorings to enhance or create authentic cooked meat, coffee, or roasted nut characteristics.
• Research and Development: Utilized in academic and industrial R&D settings for studying structure-activity relationships in flavor chemistry and exploring new synthetic pathways.

Quality Control

Our production of 2-(1-Methylethyl)-3-[(2-Methyl-3-Thienyl)Thio]Pyrazine adheres to stringent quality protocols to ensure batch-to-batch consistency and purity suitable for flavor, fragrance, and fine chemical applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as identity, assay, and impurity profiles. Our quality systems are designed to meet the expectations of FEMA, FCC, and ISO guidelines relevant to flavor ingredients.

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). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability and to minimize degradation. Keep away from strong oxidizing agents.
