Standard farmaceutici
Gli standard farmaceutici sono un insieme completo di materiali di riferimento essenziali per garantire la sicurezza, l'efficacia e la qualità dei prodotti farmaceutici. Questa categoria include standard per ingredienti farmaceutici attivi (API), che sono i componenti principali responsabili degli effetti terapeutici. Inoltre, copre composti e metaboliti rilevanti sia per l'industria farmaceutica che veterinaria, fornendo punti di riferimento per la misurazione e l'analisi precisa di queste sostanze. Gli standard di controllo delle nitrosammine sono cruciali per rilevare e mitigare le nitrosammine potenzialmente dannose nelle formulazioni di farmaci. Gli standard di tossicologia aiutano a valutare la sicurezza e i potenziali effetti avversi dei composti farmaceutici. Inoltre, gli standard per attivatori e inibitori enzimatici sono vitali per la ricerca e lo sviluppo, consentendo studi precisi delle vie biochimiche e dei meccanismi d'azione dei farmaci. Questi standard farmaceutici sono strumenti indispensabili per la conformità normativa, il controllo di qualità e la ricerca, garantendo che i prodotti farmaceutici soddisfino rigorosi criteri di sicurezza ed efficacia.

Noratropine
CAS:Noratropine is a drug that belongs to the group of anticholinergic drugs. It is used as a pharmaceutical preparation for the treatment of urinary incontinence and other conditions that are caused by overactivity of the bladder muscles. Noratropine has been shown to have a significant effect on symptoms such as increased urination, urgency, frequency, and nocturia. In addition, it reduces the amount of urine produced at night and during the day. Noratropine can be found in pueraria lobata (Kudzu) and angelicae dahuricae (Angelica). These plants contain natural compounds with anticholinergic properties. Noratropine can also be synthesized from benzalkonium chloride and n-oxide. The synthesis involves two steps: first, benzalkonium chloride reacts with an alcohol to form an acid which then reacts with n-oxide to produce noratropine.
