Descripción

4-Pentynoic acid is widely utilized as a building block for the synthesis of eight sequence-defined model oligomers. Due to its triple bond at terminal carbon, it is employed as an intermediate to produce biologically active compounds. It is used as a hypoglycemic agent, which increases liver tyrosine aminotransferase and plasma corticosterone while decreasing blood sugar in rats.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
El ácido 4-pentinóico se utiliza ampliamente como un compuesto básico para la síntesis de ocho oligómeros del modelo de secuencia definida. Debido a su triple enlace en el carbono terminal, se emplea como producto intermedio para producir compuestos biológicamente activos. Se utiliza como agente hipoglucémico, que aumenta la tirosina aminotransferasa hepática y la corticosterona plasmática mientras que disminuye el azúcar en sangre en ratas.

Solubilidad
Soluble en disolventes orgánicos de baja polaridad. Soluble en agua.

Notas
Mantener el recipiente bien cerrado en un lugar seco y bien ventilado. Incompatible con bases, agentes oxidantes y agentes reductores.
