CAS 91-20-3

Naftalina

Descrizione:

Naftalina, con il numero CAS 91-20-3, è un idrocarburo aromatico policiclico composto da due anelli di benzene fusi. Si presenta come un solido cristallino bianco a temperatura ambiente e ha un odore caratteristico che ricorda le palline di naftalina. Naftalina è insolubile in acqua ma solubile in solventi organici come etanolo, etere e benzene. Ha un punto di fusione di circa 80 gradi Celsius e un punto di ebollizione di circa 218 gradi Celsius. Naftalina è utilizzato principalmente nella produzione di anidride ftalica, come precursore per vari prodotti chimici e come repellente per le falene. Si trova anche in alcuni deodoranti e profumatori d'aria. A causa della sua struttura aromatica, Naftalina mostra una volatilità significativa e può sublimare a temperatura ambiente. Sebbene sia considerato un composto a bassa tossicità, l'esposizione può portare a problemi di salute, inclusa irritazione respiratoria e anemia emolitica nei casi gravi. Naftalina è classificato come un possibile cancerogeno umano, richiedendo un'attenta manipolazione e regolamentazione nelle applicazioni industriali.

Naphthalene

CAS: 91-20-3

Naphthalene is a chemical that is used for wastewater treatment and as a pesticide. It is also used in the manufacturing of polymers, resins, and plastics. Naphthalene has antimicrobial properties due to its hydrophobic effect. Naphthalene's antimicrobial activity is based on its ability to react with the skeleton of bacterial cells and disrupt the integrity of their outer membrane. Naphthalene also interacts with proteins and DNA, causing cell death. The molecular mechanisms of naphthalene's antibacterial activity are not well understood but have been studied using Hl-60 cells, which are immortalized human monocytic leukemia cells. This study showed that naphthalene affects the cell cycle by inhibiting protein synthesis in bacteria through binding to ribosomes or by disrupting the dna replication process.
