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:Controlled ProductFormula:C9HD3F17NO2SColor and Shape:Single SolutionMolecular weight:516.197b-Hydroxy cholesterol 3b-acetate
CAS:Controlled Product<p>7b-Hydroxy cholesterol 3b-acetate is an allylic compound that is catalyzed by molybdenum, which eliminates the acetyl group at position 7 to form a double bond with the 3-position. The reaction temperature of 7b-hydroxy cholesterol 3b-acetate can be increased to high temperatures (i.e., >100°C) for the elimination process, and allylic acetates are obtained as products. The reaction starts with the addition of hexacarbonyl, which leads to a diene intermediate. This is then eliminated by adding acetamide in presence of high concentration of acetic acid and catalytic amounts of molybdenum. The low yield and efficiency, however, are major drawbacks of this process.</p>Formula:C29H48O3Purity:Min. 95%Molecular weight:444.69 g/molRef: 3D-FH23948
Discontinued productValeric acid
CAS:<p>Valeric acid is a fatty acid that is used in the manufacture of polymers. Valeric acid can be synthesized from caproic acid, which is found in palm oil and coconut oil. Valeric acid has been shown to inhibit the activity of nicotinic acetylcholine receptors at low concentrations and to have an inhibitory effect on the ryanodine receptor at high concentrations. Valeric acid also has a matrix effect on analytical methods such as gas-liquid chromatography, which has been modeled using polymer compositions.</p>Formula:C5H10O2Purity:Min. 95%Molecular weight:102.13 g/molRef: 3D-FV34914
Discontinued productNaphthalene
CAS:<p>Naphthalene is a chemical that is used for wastewater treatment and as a pesticide. It is also used in the manufacturing of polymers, resins, and plastics. Naphthalene has antimicrobial properties due to its hydrophobic effect. Naphthalene's antimicrobial activity is based on its ability to react with the skeleton of bacterial cells and disrupt the integrity of their outer membrane. Naphthalene also interacts with proteins and DNA, causing cell death. The molecular mechanisms of naphthalene's antibacterial activity are not well understood but have been studied using Hl-60 cells, which are immortalized human monocytic leukemia cells. This study showed that naphthalene affects the cell cycle by inhibiting protein synthesis in bacteria through binding to ribosomes or by disrupting the dna replication process.</p>Formula:C10H8Purity:Min. 95%Molecular weight:128.17 g/molRef: 3D-FN10260
