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 x-ray diffraction data show that 2,2'-dipyridylamine crystallizes in a monoclinic system with an orthorhombic unit cell.</p>Formula:C10H9N3Purity:Min. 95%Molecular weight:171.2 g/mol(1'S,2'S)-Nicotine 1'-oxide
CAS:<p>Nicotine 1'-oxide is a metabolite of nicotine which is a naturally occurring alkaloid. Nicotine 1'-oxide is produced by the oxidation of nicotine and can be found in tobacco smoke, as well as in the urine of humans. Nicotine 1'-oxide has been shown to have enzyme inhibiting properties, and has been shown to decrease insulin-stimulated glucose transport rate in human liver cells. This product also has potential use as a stabilizer for pharmaceuticals or other organic substances, and can inhibit demethylation reactions that may lead to carcinogenesis. Nicotine 1'-oxide may also play a role in the transport of chemicals across membranes.</p>Formula:C10H14N2OPurity:Min. 95%Color and Shape:PowderMolecular weight:178.23 g/mol
