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:<p>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.</p>Formula:C8H9NO4Purity:Min. 95%Color and Shape:PowderMolecular weight:183.16 g/molCholesterol propionate
CAS:Controlled Product<p>Cholesterol Propionate is a monolayer film-forming polymer that forms a polymeric matrix when combined with water. The thermal expansion of this material is dependent on the concentration of cholesterol propionate and can be used as a target tissue for multi-walled carbon nanotubes (MWCNTs). In addition, Cholesterol Propionate has been shown to have light emission properties due to its hydroxyl group and fatty acid content. The phase transition temperature of the material is dependent on the concentration of benzoate in the formulation. When it reaches the phase transition temperature, cholesteryl benzoate undergoes a phase change from crystalline to liquid at room temperature. This property can be used to activate MWCNTs within Cholesterol Propionate films, which then emit light.</p>Formula:C30H50O2Purity:Min. 95%Molecular weight:442.7 g/molmeta-Cresol Purple
CAS:<p>Meta-Cresol Purple (MCP) is a fluorescent dye that is used to detect DNA polymerase chain reaction products. It is a cationic dye with an absorption maximum of 590 nm in the visible spectrum.
