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.

This color change is highly useful in titrimetric analyses (quantitative chemical analysis method) to determine the concentration of metal ions in a solution. The substrates are colored orange-yellow (absorbance maximum= 375 nm). After the enzymatic conversion, the resulting TAC shows an intense, soluble red-violet color (544 nm) in an alkaline medium (pH = 10.3).Formula:C10H9N3OSPurity:Min. 96 Area-%Color and Shape:Yellow To Orange Brown SolidMolecular weight:219.26 g/mol1-amino-2-naphthol hydrochloride
CAS:<p>1-Amino-2-naphthol hydrochloride (1ANH) is a sulphanilic compound that has been used as a test compound in flow system experiments. 1ANH reacts with methoxy groups to form an amine, which is then converted to a reactive intermediate. This intermediate can react with the hydroxy group of another molecule and produce a new product that contains both the reactive and hydroxy groups. 1ANH has been shown to be cytotoxic, inhibiting the growth of cultured cells. It also has potential as a biomarker for pharmaceutical preparations, since it may have effects on metabolism or cell proliferation.</p>Formula:C10H9NO·HClPurity:Min. 95%Color and Shape:PowderMolecular weight:195.65 g/mol3-Chloro-7-hydroxy-4-methylcoumarin
CAS:<p>3-Chloro-7-hydroxy-4-methylcoumarin is a Michaelis–Menten kinetics inhibitor that binds to the bacterial 16S ribosomal RNA and inhibits transcription and protein synthesis. This compound has been studied for wastewater treatment, where it was shown to be effective in treating sodium citrate. 3-Chloro-7-hydroxy-4-methylcoumarin is also used as an inhibitor of coumarin derivatives, which are compounds that have been shown to have antiinflammatory properties. 3CMC inhibits transcription by binding to the polymerase chain reaction (PCR) product. It has also been shown to bind to the nonpolar solvent, which prevents the formation of a complex with the enzyme DNA gyrase, leading to cell death by inhibiting protein synthesis. Fluorescence techniques have been used to study this type of inhibition in a model system.</p>Formula:C10H7ClO3Purity:Min. 95%Color and Shape:PowderMolecular weight:210.61 g/molChromotropic acid disodium dihydrate
CAS:<p>Chromotropic acid dihydrate is a chromogenic compound that has an adsorption mechanism and is used as an analytical reagent. Chromotropic acid disodium dihydrate (CDA) is used in the determination of hydrochloric acid, natural gas and other liquids. It also can be used to measure the concentration of tyramine hydrochloride. CDA has been shown to be effective in the measurement of molecular orbitals and kinetic constants. The optical sensor is sensitive to wavelengths ranging from 200-900 nm, with a peak absorption at around 500 nm. This sensor can be used for many types of chemical reactions, such as organic synthesis, hydrogenation, and oxidation.</p>Formula:C10H6O8S2Na2·2H2OPurity:Min. 95%Color and Shape:Off-White PowderMolecular weight:400.29 g/mol4'-Hydroxy-3'-nitroacetophenone
CAS:<p>4'-Hydroxy-3'-nitroacetophenone is a synthetic compound that has been used as an xanthine oxidase inhibitor. It has been shown to reversibly inhibit xanthine oxidase and prevent the accumulation of toxic metabolites that are produced by this enzyme. 4'-Hydroxy-3'-nitroacetophenone also inhibits the activities of other enzymes, such as covalent adducts with protein molecules and transfer reactions. The molecular modeling study of this compound showed that it binds to the active site of xanthine oxidase, forming a covalent adduct between the reactive oxygen species (ROS) and the phenolic OH group on the inhibitor molecule. 4'-Hydroxy-3'-nitroacetophenone was found to be safe in clinical studies, with reversible covalent binding and no inhibition of protein synthesis or cell growth at therapeutic concentrations.</p>Formula:C8H7NO4Purity:Min. 95%Color and Shape:PowderMolecular weight:181.15 g/mol4-Nitrophthalonitrile
CAS:<p>4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals.</p>Formula:C8H3N3O2Purity:Min. 95%Color and Shape:White PowderMolecular weight:173.13 g/mol4-Methoxy-3-nitrobenzoic acid methyl ester
CAS:<p>4-Methoxy-3-nitrobenzoic acid methyl ester (4MNBM) is a potent antitumor agent that inhibits tumor cell proliferation by interfering with DNA replication. 4MNBM selectively binds to the nuclear magnetic resonance and has been shown to inhibit tumor growth in animal models. This drug also shows potent antitumor activity against solid tumor cells, which is due to its ability to induce conformational changes in the DNA of these cells. 4MNBM has been shown to be selective for tumor cells, which may be due to its lack of effect on the metabolism of normal tissue and its ability to bind to proteins in tumor cell nuclei.</p>Formula:C9H9NO5Purity:Min. 95%Color and Shape:Clear LiquidMolecular weight:211.17 g/mol2,3',4,4',6-Pentahydroxybenzophenone - 85%
