CAS 77-09-8: 3,3-Bis(4-idrossifenil)ftalide
Descrizione:
3,3-Bis(4-idrossifenil)ftalide, noto anche come ftalide di bisfenolo A, è un composto organico caratterizzato dalla sua struttura, che include due gruppi idrossifenilici legati a una parte di ftalide. Questo composto è tipicamente un solido cristallino bianco o bianco sporco a temperatura ambiente. Mostra una buona stabilità termica ed è solubile in solventi organici come etanolo e acetone, ma ha una solubilità limitata in acqua. La presenza di gruppi idrossilici contribuisce al suo potenziale come blocco di costruzione nella chimica dei polimeri, in particolare nella sintesi di policarbonato e resine epossidiche. Inoltre, può presentare proprietà antiossidanti, rendendolo di interesse in varie applicazioni, tra cui plastica e rivestimenti. Tuttavia, come molti composti fenolici, può anche sollevare preoccupazioni riguardo alla interruzione endocrina, richiedendo una gestione attenta e una valutazione del suo impatto ambientale. In generale, 3,3-Bis(4-idrossifenil)ftalide è un composto versatile con implicazioni significative nella scienza dei materiali e nelle applicazioni industriali.

CAS:Phenolphthalein is a chemical compound that is used as a pH indicator. It changes color from colorless to pink in the presence of an acidic solution, and from pink to colorless in the presence of an alkaline solution. Phenolphthalein has been shown to be carcinogenic in animal models, but this effect has not been observed in humans. This product has low toxicity and can be used as a nutrient solution for plants. Phenolphthalein is also genotoxic, meaning it damages DNA, and may cause cancer or genetic mutations. The mechanism of phenolphthalein's reaction with p-nitrophenyl phosphate (pNPP) is poorly understood. The most common hypothesis suggests that phenolphthalein reacts with pNPP by forming a reactive intermediate that reacts with oxygen to form hydrogen peroxide and p-nitrophenol (pNP). This reaction produces two molecules of water as well as an unstable intermediate that decomposes intoFormula:C20H14O4Purezza:Min. 95%Colore e forma:White Clear LiquidPeso molecolare:318.32 g/molPhenolphthalein (0.04% in ca. 40% Ethanol) [for pH Determination]
