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.

CAS:Ent-Fisetinidol-(4alpha->8)-catechin-(6->4alpha)-ent-fisetinidol is a complex flavan-3-ol oligomer, which is a type of polyphenolic compound commonly found in various plant species. This compound is derived primarily from plants such as those in the genus *Acacia* and other similar species rich in condensed tannins. The mode of action of this oligomer involves its ability to engage in antioxidant activities, which include scavenging free radicals and chelating metal ions that facilitate oxidative stress in biological systems.Formula:C45H38O16Purity:Min. 95%Color and Shape:PowderMolecular weight:834.77 g/molb-Propiolactone
CAS:Controlled Product<p>b-Propiolactone is a plant extract that is found in soybeans. It has been shown to have antiviral properties and can inhibit the growth of certain viruses. b-Propiolactone binds to the active site of an enzyme called RNA polymerase, which blocks RNA synthesis and inhibits viral replication. This compound has also been shown to inhibit virus replication in vitro assays as well as antibody response against hepatitis B. The biological effects of b-propiolactone are thought to be due to its ability to bind with group p2 protein monoclonal antibodies, which may have implications for the prevention of pandemic influenza.</p>Formula:C3H4O2Purity:Min. 95%Color and Shape:Clear LiquidMolecular weight:72.06 g/mol3-Keto cholesterol
CAS:Controlled Product3-Keto cholesterol is a substance that is naturally found in the body. It is an intermediate in the production of bile acids and cholesterol, which are necessary for digestion. 3-Keto cholesterol is also involved in the synthesis of other substances, including vitamin D and steroid hormones. 3-Keto cholesterol has been shown to play a role in the prevention of coronary heart disease, as it has antioxidant properties and can prevent oxidation of low-density lipoprotein (LDL). 3-Keto cholesterol can also inhibit viral life by blocking toll-like receptor 4 (TLR4) signaling pathways. This prevents inflammatory responses caused by TLR4 activation, which may be related to atherosclerosis.Formula:C27H44OPurity:Min. 95%Color and Shape:White PowderMolecular weight:384.64 g/molL-Tyrosine tert-butyl ester
CAS:<p>L-Tyrosine tert-butyl ester is a hydrophobic analog of L-tyrosine. It is a competitive inhibitor of ATP, which slows down the second order rate constant. It also has the ability to reduce lipid hydroperoxides and maintain atp levels in cells that have been irradiated with ultraviolet light. The crystal x-ray diffraction pattern of this molecule suggests that it might be an octameric molecule, which would explain its hydrophobic properties. Its structure may be rationalized by intramolecular hydrogen bonds between the tyrosine and tert-butyl esters.</p>Formula:C13H19NO3Purity:Min. 95%Color and Shape:White PowderMolecular weight:237.29 g/mol7-Ketocholesterol
CAS:Controlled Product<p>7-Ketocholesterol is a reactive molecule that can induce inflammation and has been shown to be associated with eye disorders. 7-Ketocholesterol is an intermediate in the biosynthesis of cholesterol and is converted to 7-keto-cholesterol by the enzyme HMG-CoA reductase. This compound has also been shown to be a potent inducer of autophagy, which is a process that degrades intracellular components. 7-Ketocholesterol binds to cell nuclei and alters their shape, which may lead to cancerous cell growth. For example, this molecule induces apoptosis in cultured human retinal pigment epithelial cells. The mechanism of action for 7-ketocholesterol involves mitochondrial membrane potential, ATP binding cassette transporters, and DNA polymerase chain reaction (PCR).</p>Formula:C27H44O2Purity:Min. 95%Color and Shape:PowderMolecular weight:400.64 g/mol3-Chloro-7-hydroxy-4-methylcoumarin
CAS:<p>3-Chloro-7-hydroxy-4-methylcoumarin is a Michaelis–Menten kinetics inhibitor that binds to the bacterial 16S ribosomal RNA and inhibits transcription and protein synthesis. This compound has been studied for wastewater treatment, where it was shown to be effective in treating sodium citrate. 3-Chloro-7-hydroxy-4-methylcoumarin is also used as an inhibitor of coumarin derivatives, which are compounds that have been shown to have antiinflammatory properties. 3CMC inhibits transcription by binding to the polymerase chain reaction (PCR) product. It has also been shown to bind to the nonpolar solvent, which prevents the formation of a complex with the enzyme DNA gyrase, leading to cell death by inhibiting protein synthesis. Fluorescence techniques have been used to study this type of inhibition in a model system.</p>Formula:C10H7ClO3Purity:Min. 95%Color and Shape:PowderMolecular weight:210.61 g/mol
