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.

The former has a kinetic molecular modeling of 3.2 kcal/mol while the latter has a kinetic molecular modeling of 4.3 kcal/mol.br</p>Formula:C10H12OColor and Shape:Clear LiquidMolecular weight:148.2 g/moltrans-Chalcone
CAS:<p>Trans-chalcone is a natural compound that has been shown to inhibit bacterial growth and dna synthesis in vitro. Trans-chalcone is an oxo-flavonoid with a chalcone skeleton and two hydroxyl groups. It has been shown to have inhibitory properties against the bacterial enzyme dinucleotide phosphate (DNP) synthase, which catalyzes the synthesis of DNP from nicotinamide mononucleotide (NMN) and 5-phospho-D-ribose 1-diphosphate. Trans-chalcone is also a potential anticancer agent due to its ability to bind to response elements in DNA. This binding inhibits the transcription of genes that regulate cell proliferation. Trans-chalcone also exhibits antiinflammatory activity, which may be due to inhibition of proinflammatory cytokines such as tumor necrosis factor alpha (TNFα).</p>Formula:C15H12OPurity:Min. 95%Color and Shape:PowderMolecular weight:208.26 g/molRivaroxaban
CAS:<p>Rivaroxaban is a natural drug that is a direct factor Xa inhibitor. It has been shown to be an effective therapy for the treatment of atrial fibrillation, deep vein thrombosis (DVT) and pulmonary embolism (PE). It works by inhibiting the enzyme, thrombin, which is responsible for the formation of blood clots. Rivaroxaban also has an effect on the coagulation system by decreasing the levels of fibrinogen and increases in antithrombin III. This drug does not have any specific antidote, but it can be reversed with heparin. Pharmacodynamics and drug interactions have been studied extensively in preclinical models, demonstrated by the concentration–time curves.</p>Formula:C19H18ClN3O5SPurity:Min. 98 Area-%Color and Shape:White Off-White PowderMolecular weight:435.88 g/mol3-Bromo-5-iodobenzoic acid methyl ester

CAS:Controlled Product<p>Rotigotine is a drug that is used to treat Parkinson's disease. It is a dopamine agonist that stimulates the release of dopamine in the brain. Rotigotine has been shown to be effective in controlling symptoms of Parkinson's disease, such as tremors and stiffness, and improving motor skills. This drug has also been shown to have a good tolerability profile, with few side effects reported. Rotigotine is rapidly absorbed from the gastrointestinal tract and metabolized by CYP2D6 into desalkyl rotigotine, which are pharmacologically inactive compounds. The mean terminal half-life for rotigotine is about 2 hours.</p>Formula:C13H19NOPurity:Min. 95%Molecular weight:205.3 g/mol2',3'-Di-O-isopropylidene-5-hydroxymethyl uridine

DIOI is also a useful reagent, which may be used as a starting material for the synthesis of other compounds. It has been shown to have high quality and is available at CAS No. 3816-77-1.</p>Formula:C13H18N2O7Purity:Min. 95 Area-%Color and Shape:PowderMolecular weight:314.29 g/molIndole-3-acetyl-L-aspartic acid
CAS:<p>Indole-3-acetyl-L-aspartic acid, also known as 3IAA or IAA, is a naturally occurring amino acid. It is used in the study of plant physiology and serves as a substrate for ATP synthesis. 3IAA is synthesized from tryptophan by the enzyme indole acetyltransferase. The kinetic data obtained with 3IAA can be used to compare the effects of light exposure on ATP levels in plants. Indole-3-acetyl-L-aspartic acid inhibits cell growth and induces apoptosis, which may be due to its ability to inhibit protein synthesis by preventing RNA and DNA synthesis. This compound has been shown to have surface membrane inhibiting properties, which may be due to its ability to cross the plasma membrane.</p>Formula:C14H14N2O5Purity:Min. 95%Color and Shape:White PowderMolecular weight:290.27 g/mol3-Amino-3'-nitrobiphenyl hydrochloride
