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:Controlled Product<p>Cresyl violet acetate is a dye that is used in histology to stain tissue sections. It binds to basic proteins, such as those found in the cytoplasm and nucleus, and has a strong affinity for nucleic acids. Cresyl violet acetate can be used to identify inflammatory lesions and other biological samples. The dye has been shown to induce neuronal death by reducing the redox potentials of neurons through the activation of Toll-like receptors (TLRs). Basic proteins are also involved in oral hypoglycaemic activity.</p>Formula:C18H15N3O3Purity:Limit? 65.%Color and Shape:PowderMolecular weight:321.33 g/mol
