1,2-Ethanedithiol (CAS 540-63-6) is a colorless, flammable liquid with a strong garlic-like odor, primarily used as a cation scavenger in trifluoroacetic acid (TFA) peptide-cleavage cocktails, a metal chelating agent, and in organic synthesis for disulfide bond formation. It is also employed in semiconductor manufacturing and as a reagent in analytical chemistry. This chemical has a molecular formula of C2H6S2 and a molecular weight of 94.20 g/mol. It should be stored at ambient conditions but handled with caution, as it carries a "Danger" signal word due to its toxicity and flammability. Molekula supplies 1,2-Ethanedithiol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
Este producto está disponible en Molekula bajo consulta. La especificación completa, la Hoja de Datos de Seguridad (SDS) y la documentación del Certificado de Análisis (CoA) se proporcionarán con su cotización una vez que nuestro equipo confirme el grado y el tamaño de envío que necesite.
