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:L-Serine beta-naphthylamide (LSNA) is a biochemical that is used to treat meningitis caused by Neisseria meningitidis, which is resistant to penicillin. LSNA is an amphipathic molecule and has a carboxyl group on one end and a amide group on the other. It is soluble in water, but dissolves poorly in organic solvents such as chloroform or ether. LSNA inhibits the growth of N. meningitidis by binding to the bacterial cell membrane and causing lysis of the cell wall. This action can be attributed to its amphipathic nature, which allows it to pass through the lipid bilayer of the bacterial membrane.
