Hidrógeno ftalato de potasio

Descripción:

Hidrógeno ftalato de potasio (KHP), con el número CAS 877-24-7, es un sólido cristalino blanco que se utiliza comúnmente como estándar primario en titulaciones ácido-base debido a su estabilidad y naturaleza no higroscópica. Es la sal potásica del ácido ftálico y tiene la fórmula química KHC8H4O4. KHP es soluble en agua, lo que lo hace adecuado para preparar soluciones estándar, y tiene un punto de fusión relativamente alto. La sustancia se utiliza a menudo en química analítica para calibrar medidores de pH y determinar la concentración de bases. KHP exhibe propiedades ácidas, ya que puede donar un protón (H+) en solución, lo cual es esencial para su papel en las titulaciones. Además, es no tóxico y respetuoso con el medio ambiente, lo que lo convierte en una opción preferida en entornos de laboratorio. Su estructura molecular incluye un grupo ftalato, que contribuye a su comportamiento químico e interacciones. En general, Hidrógeno ftalato de potasio es un reactivo valioso en análisis cuantitativos y laboratorios educativos.

Potassium hydrogen phthalate

CAS: 877-24-7

Potassium hydrogen phthalate is a corrosion inhibitor and a co-catalyst for the production of polyvinyl chloride. It has been shown to exhibit toxic effects on the central nervous system, liver, and kidneys in animal studies. Potassium hydrogen phthalate is also used as a corrosion inhibitor in wastewater treatment plants. The toxicity of potassium hydrogen phthalate may be due to its ability to inhibit ryanodine receptor, an intracellular calcium release channel that regulates cellular functions such as muscle contraction, enzyme activities, and cell cycle progression. Potassium hydrogen phthalate can also be used to produce polyvinyl chloride. It has been shown to have toxic effects on insects as well as thermodynamic data related to water vapor. Potassium hydrogen phthalate is an analytical reagent that can be used for picolinic acid determination.
