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:<p>Onjisaponin B is a triterpenoid saponin that has been shown to have anti-angiogenic effects, neuroprotective properties, and autophagy inducing activity. Onjisaponin B has also been shown to inhibit the production of tumor necrosis factor-α (TNF-α) in cultured PC12 cells. The anti-inflammatory effects of this compound may be due to its ability to induce autophagy. This compound induces autophagy by activating the mechanistic target of rapamycin (mTOR) pathway, which leads to the induction of autophagy through the activation of AMP kinase. Onjisaponin B has been found in plants used in traditional Chinese medicine and other Asian countries.</p>Formula:C75H112O35Purity:Min. 95%Color and Shape:White PowderMolecular weight:1,573.67 g/molo-Nitrocinnamaldehyde
CAS:<p>o-Nitrocinnamaldehyde is an aldehyde that belongs to the group of β-unsaturated aldehydes. It has been shown to inhibit cancer cell growth in vitro and in vivo. o-Nitrocinnamaldehyde inhibits xanthine oxidase by preventing the oxidation of hypoxanthine to xanthine and xanthine to uric acid. This prevents the formation of superoxide radicals, which are known carcinogens. The compound also inhibits aldehyde dehydrogenase, which prevents the oxidation of nitro compounds that have been generated by nitrosation reactions. These reactions are catalyzed by nitric oxide synthases (NOS) and convert nitrate into nitrite and then into reactive nitrogen species such as peroxynitrites. o-Nitrocinnamaldehyde also inhibits uv absorption, which may be due to its ability to form supramolecular aggregates with other organic molecules or metal ions.</p>Formula:C9H7NO3Purity:Min. 95%Molecular weight:177.16 g/mol4-Chloro-3-hydroxybenzoic acid methyl ester

CAS:<p>Formyl-L-methionine is a form of methionine produced by the human body. It is found in proteins, peptides, and polypeptides as an amino acid residue. Methionine is one of the essential amino acids needed by humans. Methionine can be converted to formyl-L-methionine by the enzyme methioninase, which is found in bacteria such as Escherichia coli. The conversion of methionine to formyl-L-methionine may be important for antigen binding sites on antibodies. The N-terminal part of the protein can be recognized by antibodies, which are then able to bind to antigenic determinants on bacteria and other pathogens.</p>Formula:C6H11NO3SPurity:Min. 95%Color and Shape:PowderMolecular weight:177.22 g/mol1-(4-Aminophenyl)ethanone oxime
