Étalons pharmaceutiques
Les standards pharmaceutiques sont un ensemble complet de matériaux de référence essentiels pour garantir la sécurité, l'efficacité et la qualité des produits pharmaceutiques. Cette catégorie comprend des standards pour les ingrédients pharmaceutiques actifs (APIs), qui sont les composants principaux responsables des effets thérapeutiques. De plus, elle couvre les composés et métabolites pertinents pour les industries pharmaceutique et vétérinaire, fournissant des points de référence pour la mesure et l'analyse précises de ces substances. Les standards de contrôle des nitrosamines sont cruciaux pour détecter et atténuer les nitrosamines potentiellement nocives dans les formulations médicamenteuses. Les standards de toxicologie aident à évaluer la sécurité et les effets indésirables potentiels des composés pharmaceutiques. En outre, les standards pour les activateurs et les inhibiteurs enzymatiques sont essentiels pour la recherche et le développement, permettant des études précises des voies biochimiques et des mécanismes des médicaments. Ces standards pharmaceutiques sont des outils indispensables pour la conformité réglementaire, le contrôle de qualité et la recherche, garantissant que les produits pharmaceutiques répondent à des critères stricts de sécurité et d'efficacité.

1,2-Dihydrobudesonide
CAS :<p>1,2-Dihydrobudesonide is a synthetic glucocorticosteroid that has a molecular structure similar to prednisolone. It is used for the treatment of inflammatory skin conditions such as eczema and psoriasis. 1,2-Dihydrobudesonide has been shown to have a high oral bioavailability and low systemic bioavailability. The molecule is metabolized in the liver to produce hydrocortisone, which accounts for its oral bioavailability. 1,2-Dihydrobudesonide is classified as an acetal because it contains an acetal linkage between the 16-carbon (C16) steroid nucleus and the 17-carbon (C17) side chain. This connection results in a more stable molecule than desonide, which is not acetalated.
