CAS 67-56-1: Methanol
Beschreibung:
Methanol, auch bekannt als Methanol, ist ein einfaches Alkohol mit der chemischen Formel CH₃OH und der CAS-Nummer 67-56-1. Es ist eine farblose, flüchtige Flüssigkeit mit einem leicht süßlichen Geruch und ist hochgradig wasserlöslich. Methanol hat einen niedrigen Siedepunkt und einen hohen Dampfdruck, was es zu einer brennbaren Substanz macht, die explosive Gemische mit Luft bilden kann. Es wird als Lösungsmittel, Frostschutzmittel, Brennstoff und als Ausgangsstoff für die Herstellung von Formaldehyd und anderen Chemikalien verwendet. Methanol ist für den Menschen giftig, wobei die Einnahme oder längere Exposition zu schweren gesundheitlichen Auswirkungen führen kann, einschließlich metabolischer Azidose und Schädigung des Sehnervs, was möglicherweise zur Erblindung führen kann. Seine Herstellung erfolgt typischerweise durch die katalytische Umwandlung von Erdgas oder Biomasse. Methanol gewinnt auch als potenzielle erneuerbare Energiequelle und als Brennstoff für Brennstoffzellen an Bedeutung. Aufgrund seiner Eigenschaften ist es wichtig, Methanol mit Vorsicht zu behandeln und geeignete Sicherheitsprotokolle zu befolgen, um die mit seiner Toxizität und Entflammbarkeit verbundenen Risiken zu mindern.

CAS:Kontrolliertes ProduktNorcarfentanil oxalate is a potent synthetic opioid that is used as an intravenous anesthetic. It has been approved for use in veterinary medicine to induce and maintain general anesthesia. Norcarfentanil oxalate is metabolized by amination to norcarfentanil-N-oxide, which is the major metabolic product of this drug. The pharmacokinetic modeling of this compound has shown that its half-life ranges from 4 to 8 hours, with a peak plasma concentration occurring 1 hour after administration. Norcarfentanil oxalate's side effects include depression, anxiety, and psychotic disorders. These side effects are more common in women than in men. Other side effects include serotonin syndrome and serotonin reuptake inhibitor (SSRI) discontinuation syndrome.Formel:C16H22N2O3•C2H2O4Reinheit:Min. 95%Molekulargewicht:380.39 g/mol
