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.

The compound inhibits aminoglycoside-induced protein synthesis in eukaryotic cells and may be useful in understanding the mechanism of action and resistance to these antibiotics.</p>Formula:C6H5N3O5Purity:Min. 98 Area-%Color and Shape:Yellow PowderMolecular weight:199.12 g/mol4'-Bromoflavone
CAS:<p>4'-Bromoflavone is a flavonoid with potent enzyme-inducing properties. It has been shown to affect transcriptional regulation in murine hepatoma cells. 4'-Bromoflavone was also found to be an effective inducer of phase II detoxification enzymes, such as glutathione S-transferase and quinone reductase in the liver of humans. This drug also affects protein synthesis and enzyme activities in mice, rats, and human cells.</p>Formula:C15H9BrO2Purity:Min. 95%Color and Shape:PowderMolecular weight:301.13 g/molCitronellyl nitrile

CAS:<p>L-Asparagine methyl ester hydrochloride is a pediatric drug that is used in the treatment of oral mucositis, which is a side effect of chemotherapy. L-Asparagine methyl ester hydrochloride can be administered by mouth, and provides relief for patients with mucosal ulceration, pain or discomfort. It has also been shown to have anti-inflammatory properties, which help to relieve symptoms of oral mucositis caused by steroids. In addition it has been shown to prevent the development of lymphoblastic leukemia in mice. L-Asparagine methyl ester hydrochloride inhibits the growth of cancer cells through its effects on lymphocytes and lymphoblasts.</p>Formula:C5H10N2O3·HClPurity:Min. 95%Color and Shape:PowderMolecular weight:182.61 g/mol3-Chloro-L-tyrosine
CAS:<p>3-Chloro-L-tyrosine (3CT) is a reactive, nitrogen containing molecule that has been used as a model system to study oxidative injury in the heart. The molecule reacts with the air and oxygen in the environment, producing reactive oxygen species (ROS) that can cause oxidative injury. 3CT has been shown to inhibit ATP binding cassette transporter A1 (ABCA1), which is involved in cholesterol efflux from macrophages. 3CT also promotes the release of eosinophil peroxidase from eosinophils and induces tumor necrosis factor alpha (TNF-α). The analytical method for 3CT includes liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS).</p>Formula:C9H10NO3ClPurity:Min. 95%Color and Shape:PowderMolecular weight:215.63 g/mol2-(2,3-Naphthalimino)ethyl trifluoromethanesulfonate
CAS:<p>2-(2,3-Naphthalimino)ethyl trifluoromethanesulfonate (2NTF) is a nonsteroidal anti-inflammatory drug that acts by inhibiting the enzyme cyclooxygenase. It is used as a sample preparation agent for epoxyeicosatrienoic acids (EETs). 2NTF is applied to a hydrophilic interaction chromatography column and then eluted with caproic acid, which selectively binds to the fatty acid component of EETs. The eluate can then be analyzed using a fluorescence detector and chromatographic methods. 2NTF has been shown to have no effect on carnitine levels in human serum.</p>Formula:C15H10F3NO5SPurity:Min. 97%Color and Shape:White PowderMolecular weight:373.3 g/mol6-Fluorovitamin D3
CAS:<p>6-Fluorovitamin D3 is a synthetic analog of vitamin D3, which is a modified form of the naturally occurring hormone known as cholecalciferol. This molecule is typically derived through chemical synthesis, incorporating a fluorine atom at a specific position on the vitamin D3 structure. The introduction of the fluorine atom is designed to enhance the stability of the compound and potentially alter its biological activity.</p>Formula:C27H43FOPurity:Min. 95%Molecular weight:402.63 g/mol
