2-Pyrazinylethanethiol, identified by its CAS number 35250-53-4, is a fascinating organic compound that bridges the worlds of flavor chemistry and advanced organic synthesis. Its molecular structure, featuring a pyrazine heterocyclic ring linked to an ethanethiol chain, dictates its unique chemical properties and broad utility. Understanding these characteristics is essential for chemists and formulators aiming to harness its potential.

Chemically, 2-Pyrazinylethanethiol (C6H8N2S, Molecular Weight: 140.21) presents as a liquid, typically appearing white to yellow and transparent. Its boiling point is around 105-110 °C at 20 mm Hg, with a flash point exceeding 230 °F. The presence of the thiol (-SH) group confers significant reactivity, making it susceptible to oxidation and capable of participating in nucleophilic substitution reactions. This thiol functionality is also responsible for its characteristic strong, savory, and sulfurous odor, a key attribute in flavor applications. Its solubility in most organic solvents facilitates its use in various reaction media, although its water solubility is limited.

The significance of 2-Pyrazinylethanethiol in organic synthesis cannot be overstated. It serves as a versatile building block, allowing for the introduction of the pyrazine moiety into more complex molecules. This is particularly valuable in the pharmaceutical and agrochemical sectors, where pyrazine derivatives often exhibit desirable biological activities. Researchers can buy this intermediate to explore novel drug candidates, develop new pesticides, or synthesize specialty materials. The ability to reliably purchase high-purity 2-Pyrazinylethanethiol from manufacturers in China ensures that R&D projects can proceed without interruption due to material availability or quality issues.

The compound’s role as a flavor agent is equally important. Its complex aroma profile, often described as meaty, roasted, or savory, makes it a sought-after ingredient for enhancing the taste of food products. From processed meats to savory snacks and even certain beverages, 2-Pyrazinylethanethiol contributes authentic and desirable flavor notes.

For professionals in these fields, securing a dependable source for 2-Pyrazinylethanethiol is crucial. Reputable suppliers offer detailed specifications, safety data sheets (SDS), and competitive pricing, especially for bulk orders. Engaging with manufacturers directly can often provide the best value and ensure the consistent quality required for both sensitive flavor applications and demanding synthetic routes. When seeking this essential chemical intermediate, prioritize suppliers known for their quality control and customer support.
