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.

Bromocresol purple sodium salt
CAS:<p>Bromocresol purple sodium salt is a dye that emits light when it is irradiated with light of a particular wavelength. It has been used to detect amniotic fluid contamination in the laboratory and as an absorber in polymer films. Bromocresol purple sodium salt absorbs ultraviolet and visible light, which causes it to emit red light. The molecules of bromocresol purple sodium salt are long-chain triazoles, which absorb water vapor and emit infrared radiation. This property can be used to detect the presence of alkali metals. The luminescent property of bromocresol purple sodium salt can be enhanced by adding an alkali metal, such as potassium or lithium chloride, to the solution where it is dissolved.</p>Formula:C21H15Br2O5S·NaPurity:Min. 95%Molecular weight:562.2 g/molAcetyl-D-methionine
