Hidrogenoftalato de potássio

Descrição:

Hidrogenoftalato de potássio (KHP), com o número CAS 877-24-7, é um sólido cristalino branco que é comumente usado como padrão primário em titulações ácido-base devido à sua estabilidade e natureza não higroscópica. É o sal de potássio do ácido ftálico e tem a fórmula química KHC8H4O4. KHP é solúvel em água, tornando-o adequado para preparar soluções padrão, e tem um ponto de fusão relativamente alto. A substância é frequentemente utilizada em química analítica para calibrar medidores de pH e determinar a concentração de bases. KHP exibe propriedades ácidas, pois pode doar um próton (H+) em solução, o que é essencial para seu papel nas titulações. Além disso, é não tóxico e ambientalmente amigável, tornando-se uma escolha preferida em ambientes de laboratório. Sua estrutura molecular inclui um grupo ftalato, que contribui para seu comportamento químico e interações. No geral, Hidrogenoftalato de potássio é um reagente valioso em análises quantitativas e laboratórios educacionais.

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.
