p-Nitrofenil palmitato

Descripción:

p-Nitrofenil palmitato es un compuesto orgánico que sirve como sustrato en ensayos bioquímicos, particularmente para el estudio de lipasas y esterasas. Es un éster formado a partir de ácido palmítico y p-nitrofenol, caracterizado por su larga cadena de ácido graso hidrofóbico y un grupo nitrofenilo polar. Este compuesto es típicamente un sólido blanco a amarillo pálido a temperatura ambiente y es soluble en disolventes orgánicos como etanol y acetona, pero tiene una solubilidad limitada en agua debido a su naturaleza hidrofóbica. Al hidrolizarse, p-Nitrofenil palmitato libera p-nitrofenol, que puede cuantificarse espectrofotométricamente, lo que lo hace útil para ensayos de actividad enzimática. La presencia del grupo nitro aumenta la reactividad del compuesto y proporciona una propiedad cromogénica, lo que permite una fácil detección y medición. Además, es importante manejar este compuesto con cuidado, ya que el p-nitrofenol es tóxico y puede representar riesgos para la salud si se ingiere o inhala.
