Certificado ISO 9001:2015 e ISO 14001:2015 · Suministro a laboratorios e industria desde el año 2000 · Certificado de Análisis (CoA) con cada lote
Propionic acid (CAS 79-09-4) is a naturally occurring, colorless liquid carboxylic acid with a pungent odor, widely used as a preservative in food, animal feed, and pharmaceuticals to inhibit mold and bacteria growth. It also serves as a building block in chemical synthesis, including plastics and fragrances. This USP-grade propionic acid has the molecular formula CH3CH2COOH and a molecular weight of 74.08. It is stored at ambient conditions, requires careful handling (Signal Word: Danger), and meets strict pharmaceutical standards. Molekula supplies Propionic acid from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
