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.

L-Phenylalanine b-naphthylamide
CAS:L-Phenylalanine b-naphthylamide is a phenylalanine derivative that can be used as an indicator for the detection of Clostridium, 2-naphthylamine, and other anaerobes. This compound is a chromogenic substrate that reacts with amino groups in amino acids and amides in peptides to form a variety of color products. The condensation of phenylalanine with 2-naphthylamine is catalyzed by enzymes found in clostridia. When L-phenylalanine b-naphthylamide is incubated with tissue from animals or humans, it produces a pink coloration that indicates the presence of clostridia. The aerobic conditions necessary for this reaction are also found in the environment and within the body.Formula:C19H18N2OPurity:Min. 95%Molecular weight:290.36 g/mol4-Nitrophenol
CAS:4-Nitrophenol is a chemical compound that is used in wastewater treatment to remove iron and copper ions. 4-Nitrophenol has been shown to catalyze the oxidation of picolinic acid by copper chloride, forming oxalic acid.
