Pharmaceutical Standards
Pharmaceutical standards are a comprehensive set of reference materials essential for ensuring the safety, efficacy, and quality of pharmaceutical products. This category includes standards for active pharmaceutical ingredients (APIs), which are the core components responsible for therapeutic effects. Additionally, it covers compounds and metabolites relevant to both the pharmaceutical and veterinary industries, providing benchmarks for the accurate measurement and analysis of these substances. Nitrosamine control standards are crucial for detecting and mitigating potentially harmful nitrosamines in drug formulations. Toxicology standards help assess the safety and potential adverse effects of pharmaceutical compounds. Furthermore, enzyme activators and inhibitors standards are vital for research and development, enabling precise studies of biochemical pathways and drug mechanisms. These pharmaceutical standards are indispensable tools for regulatory compliance, quality control, and research, ensuring that pharmaceutical products meet stringent safety and effectiveness criteria.

1,3-Dimethylnaphthalene
CAS:<p>1,3-Dimethylnaphthalene is a chemical intermediate that is used for the synthesis of perfumes and pharmaceuticals.</p>Formula:C12H12Purity:Min. 95%Molecular weight:156.22 g/molEltrombopag olamine
CAS:Eltrombopag olamine is an orally active drug that belongs to the class of thiazolidinones. It has been used for the treatment of thrombocytopenia in patients with chronic liver disease and myelodysplastic syndrome. Eltrombopag olamine inhibits platelet aggregation by binding to glycoprotein IIb/IIIa receptors on the surface of platelets. The drug is a prodrug that is metabolized in vivo to its active form, eltrombopag. This conversion is catalysed by CYP3A4 and CYP2D6 enzymes and can be inhibited by drugs that inhibit these enzymes, such as trifluoroacetic acid and hydroxyl group-containing compounds. Eltrombopag olamine binds to erythrocytes, which may be due to its ability to form intramolecular hydrogen bonds with nitrogen atoms.

CAS:1-(2-Nitrophenyl)-1,2-ethanediol is a chemical that has been shown to inhibit the glutamate-induced increase in cytosolic Ca2+ concentration. It also prevents the loss of membrane integrity and protects against cell death by inhibiting apoptosis. 1-(2-Nitrophenyl)-1,2-ethanediol also inhibits amp-activated protein kinase activity and increases ATP production. These effects may be due to its ability to reduce intracellular Ca2+ levels and prevent Ca2+ overload in mitochondria. 1-(2-Nitrophenyl)-1,2-ethanediol has been shown to have a protective effect on isolated heart cells and ventricular myocytes from hypoxia/reoxygenation injury and is an effective model system for investigating biochemical properties of glutamate excitotoxicity.Formula:C8H9NO4Purity:Min. 95%Color and Shape:PowderMolecular weight:183.16 g/mol4-Fluorotropacocaine
CAS:Controlled Product<p>4-Fluorotropacocaine is a synthetic, serotonergic compound that has been shown to have similar effects in the brain as diazepam. 4-Fluorotropacocaine has been postulated to be a supplement and is thought to have neuroprotective properties. It binds to serotonin receptors and inhibits the reuptake of serotonin by neurons. This inhibition causes an increase in the level of serotonin in the synaptic cleft, which can lead to symptoms such as nausea, vomiting, and headache. 4-Fluorotropacocaine may also inhibit dopamine reuptake leading to symptoms such as hallucinations, delusions, and confusion. Structural analogs of 4-fluorotropacocaine are often used in research studies because they can be synthesized with various substitutions on the benzene ring.</p>Formula:C15H18FNO2Purity:Min. 95%Molecular weight:263.31 g/mol24,25-Dihydroxy vitamin D2

It has been shown to inhibit acid formation in the liver and to stimulate growth in some types of cancer cells. 9-cisRetinol is converted to all-trans retinoic acid, which is a nuclear hormone receptor that regulates gene expression. It also has been shown to be effective in clinical studies for the treatment of congenital amaurosis and cancer. 9-cisRetinol can inhibit phospholipase A2, which prevents the release of arachidonic acid from membrane phospholipids, as well as inhibit prostaglandin synthesis. The optimum pH for 9-cisRetinol activity is between 7 and 8.</p>Formula:C20H30OPurity:Min. 95%Molecular weight:286.45 g/mola,O-Dimethyl serotonin
CAS:Controlled Product<p>a,O-Dimethyl serotonin is a monoamine compound that is synthesized by the enzymatic decarboxylation of 5-hydroxytryptophan. It has been shown to increase dopamine levels and inhibit the enzyme activity of serotonin in mice. This drug also binds to 5-ht2 receptors and induces the release of serotonin from nerve cells. A linear calibration curve was obtained using bufotenin as a standard. This drug has been used in analytical toxicology for determining the uptake of serotonin into human lung tissue and its effect on 5-ht1a receptors. In addition, a study was conducted with perennial ryegrass to determine whether this drug inhibits plant toxin synthesis.
