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.

2,6-Bis(hydroxymethyl)-p-cresol
CAS:<p>2,6-Bis(hydroxymethyl)-p-cresol (BHMC) is a cross-linking agent that reacts with the hydroxyl groups of polymers to form covalent bonds. This reaction is irreversible and has been shown to be effective in thermal expansion applications. BHMC is insoluble in water and so can be used as a proton donor for the synthesis of polymer hydrogels. BHMC has also been used as a molecular modeling probe for studying protein structure and function. This compound reacts with nucleophiles by nucleophilic attack on the carbonyl carbon atom, producing an intermediate that tautomerizes to the corresponding enone. The reaction mechanism involves formation of a tetranuclear transition state followed by acid catalysis. Functional groups such as -OH, -NH2, or -COOH are required for this reaction to occur. NMR spectra have shown that there are three different chemical structures</p>Formula:C9H12O3Purity:Min. 95%Color and Shape:PowderMolecular weight:168.19 g/mol(16a)-21-(Acetyloxy)-16-methyl-pregna-1,4,9(11)-triene-3,20-dione

This amino acid can also regulate the release of l-threonine from cells, which affects serum levels. Acetyl-L-threonine has been shown to increase the glomerular filtration rate, which may be due to its ability to increase coagulation.</p>Formula:C6H11NO4Purity:Min. 95%Color and Shape:PowderMolecular weight:161.16 g/molIsovaleryl-Phe-Nle-Sta-Ala-Sta-OH
CAS:<p>Isovaleryl-Phe-Nle-Sta-Ala-Sta-OH (IVAS) is a small molecule that has been shown to be an angiotensin system inhibitor. IVAS blocks the binding site of the angiotensin receptor and prevents the activation of this system. This effect is dose dependent and can be used to treat high blood pressure in humans. IVAS is a long-acting drug and has been shown to be effective in primates as well as humans. The drug is rapidly absorbed from the gastrointestinal tract and eliminated by metabolism, mainly through hydrolysis by esterases or glucuronidases, oxidation by cytochrome P450 enzymes, reduction by glutathione reductase, or conjugation with glucuronic acid. IVAS also specifically binds to markers expressed at high levels in Mycobacterium tuberculosis strains (e.g., ESX-1 secretion system protein) and inhibits cell growth in culture.</p>Formula:C39H65N5O9Purity:Min. 95%Molecular weight:747.96 g/molN-(4-Bromonaphthalene-1-yl)-acetamide

CAS:<p>Proflavine hemisulfate is an antibiotic that inhibits bacterial growth by binding to DNA and inhibiting DNA synthesis. It binds to the dinucleotide phosphate of the bacterial ribosome and changes the shape of the nucleotide, preventing attachment of amino acids to form proteins. Proflavine hemisulfate also has a strong affinity for nuclear dna and is bound to it in a form that inhibits replication. The free form of proflavine is converted into enzyme form by phosphorylation, which inhibits protein synthesis and cell division. Proflavine hemisulfate has been shown to inhibit multidrug efflux pumps in bacteria, leading to increased susceptibility of bacteria to antibiotics. In addition, proflavine hemisulfate possesses inhibitory properties against transfer reactions in cells. The method used for measuring proflavine hemisulfate activity is electrochemical impedance spectroscopy (EIS) on cell nuclei suspensions in a model system.</p>Formula:C13H11N3•(H2SO4)0•(H2O)xPurity:Min. 95%Color and Shape:PowderMolecular weight:258.29 g/molPravastatin 1,1,3,3-tetramethylbutylamine
