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.
