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-(3,4-Methylenedioxyphenyl) 2-nitropropene
CAS :<p>1-(3,4-Methylenedioxyphenyl) 2-nitropropene (1-MPNP) is a phosphatase inhibitor that is active against gram-negative bacteria by inhibiting enterotoxins and chlamydia. 1-MPNP inhibits the activity of tyrosine phosphatases, which are enzymes that play a major role in bacterial virulence. 1-MPNP competitively inhibits the activity of tyrosine phosphatases and prevents them from catalyzing the hydrolysis of polyphosphate substrates. This inhibition leads to an accumulation of polyphosphates in the bacterial cell membrane, which disrupts its permeability and leads to cell death.</p>Formule :C10H9NO4Degré de pureté :Min. 97.5 Area-%Couleur et forme :Yellow PowderMasse moléculaire :207.18 g/molHydrocinnamoin
CAS :<p>Hydrocinnamaldehyde is a reactive aldehyde that is used for the synthesis of other compounds. It can be obtained by catalyzing the oxidative cleavage of cinnamyl alcohol. Hydrocinnamaldehyde is also found in marine environments, where it reacts with oxygen to form an unstable compound called hydrocinnamic acid. Hydrocinnamic acid then undergoes an oxidation-reduction process that converts it to hydrocinnamaldehyde. Hydrocinnamaldehyde is one of two carbene precursors used in the Grubbs reaction, which allows for the selective formation of C-C bonds from alkenes and alkynes. The other carbene precursor, methyllithium, is commercially unavailable and has been replaced by hydrocinnamaldehyde as a more economical alternative in this reaction.<br>Hydrocinnamaldehyde can also be used to synthesize palytoxin, which is a toxic compound found in shellfish such as oysters and clams</p>Formule :C18H18O2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :266.33 g/molMethyl 4-aminocinnamate

CAS :Produit contrôlé<p>Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) that is used in the treatment of depression, obsessive-compulsive disorder, and other disorders. It is also used to reduce the symptoms of premenstrual dysphoric disorder. Fluoxetine inhibits the reabsorption of serotonin by neurons, which increases the levels of this neurotransmitter in the synaptic space. Fluoxetine hydrochloride binds to serotonergic receptors in the brain that are believed to be involved in mood control and depression. SSRIs act as an active inhibitor of serotonin synthesis, thereby increasing its availability. Studies have shown that fluoxetine can inhibit the proliferation of cancer cells by inhibiting bcl-2 protein expression and promoting apoptosis.</p>Formule :C17H19ClF3NODegré de pureté :Min. 98 Area-%Couleur et forme :White PowderMasse moléculaire :345.79 g/molPerylene
