Aplicaciones

Isovaleraldehyde acts as a reagent in the preparation of active pharmaceutical ingredient (API) products. It serves as an internal standard for the determination of wine aroma carbonyl compounds with 5-8 carbon atoms. Further, it is utilized as a standard to evaluate the quality of olive oils by headspace solid-phase microextraction-gas chromatography using flame ionization detection and multivariate analysis. In addition to this, it is employed to enhance the taste and odor of the food.

Notas

Light and air sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents, bases, alkaline materials and reducing agents. Store in a cool place.
