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>1,3-Dipropylurea is a nucleophilic organic compound. It is soluble in organic solvents such as benzyl alcohol, nitrous oxide, and ethylene glycol. It also has a constant boiling point of 215°C at atmospheric pressure. The reaction rate for the formation of 1,3-dipropylurea from benzaldehyde and propylene oxide is dependent on the solvent used. The yields are higher in polar solvents such as nitrous oxide or ethylene glycol than in nonpolar solvents like benzene or hexane. This reaction can be catalyzed by cyanoborohydride and the use of a base such as sodium hydroxide or potassium tert-butoxide speeds up the reaction rate considerably.</p>Formula:C7H16N2OPurity:Min. 97 Area-%Color and Shape:PowderMolecular weight:144.21 g/molL-Methionine sulfone

CAS:<p>(2-Naphthyloxy)acetyl chloride is an inhibitor of alcohol dehydrogenase, which is the enzyme that catalyzes the conversion of ethanol to acetaldehyde. It has been shown to be active against grapevine, but not against the yeast Saccharomyces cerevisiae. (2-Naphthyloxy)acetyl chloride inhibits alcohol dehydrogenase with a potency comparable to hexanol and ethylene glycol. It also inhibits esterases, which may account for its inhibitory effect on vinifera l. (2-Naphthyloxy)acetyl chloride has been shown to be more selective in inhibiting both alcohol and aldehyde dehydrogenases than hexanol or ethylene glycol.</p>Formula:C12H9ClO2Purity:Min. 95%Color and Shape:Off-White PowderMolecular weight:220.65 g/mol2'-Aminoacetanilide
CAS:<p>2'-Aminoacetanilide is a colorless, crystalline compound that is soluble in water and has a bitter taste. It is used as an acidity regulator in food products, particularly bakery products. 2'-Aminoacetanilide can be found naturally in some microflora, such as lactic acid bacteria. <br>2'-Aminoacetanilide is an aromatic amine that contains both primary amino and functional groups. It is nucleophilic and reacts with proton by nucleophilic attack to form the corresponding amide or carbonyl group. 2'-Aminoacetanilide also has the ability to react with nitro compounds to form an amido-nitro adduct.</p>Formula:C8H10N2OPurity:Min. 95%Color and Shape:PowderMolecular weight:150.18 g/molCresol red
CAS:<p>Cresol red is a weak diacidic molecule and an anionic dye largely used in genetic and biochemical studies. Cresol red is commonly used to measure the pH of aqueous solutions also from environmental samples, e.g. seawater (Byrne, 1989). Cresol red shows an increased protonation in acidic water-based solutions at low temperatures (Heger, 2006). Cresol red can be used to introduce pH-sensing features to sensing materials, such as, optical fibres or nanoparticles (Islam, 2021).</p>Formula:C21H18O5SColor and Shape:Brown Red PowderMolecular weight:382.43 g/mol2,3,5-Trimethyl-4-nitropyridine 1-oxide
CAS:<p>The reaction of 2,3,5-trimethyl-4-nitropyridine 1-oxide with hydrogen peroxide is an example of a peroxide reaction. The HOOH molecule is a nucleophilic and attacks the CNO group. This leads to the formation of a new bond between the oxygen and carbon atoms in the molecule. The oxygen atom then becomes an oxidizing agent, which can react with other molecules in order to form more products. In this reaction, hydrogen peroxide is used as an oxidizing agent to produce chlorine gas, water vapor, and nitric oxide gas. The reaction can be summarized as follows: 2CNO + 3HOOH → 4CO + 2O + 3N2O + 3HO2</p>Formula:C8H10N2O3Purity:Min. 95%Color and Shape:PowderMolecular weight:182.18 g/mol2-(2,4-Dinitrophenoxy)ethanol
CAS:<p>2-(2,4-Dinitrophenoxy)ethanol is a glycol ether that has been shown to be an effective nucleophile in nucleophilic substitution reactions. It is a colorless liquid with a boiling point of between 204°C and 205°C. 2-(2,4-Dinitrophenoxy)ethanol reacts with deionized water in the presence of ethylene to produce a crystalline precipitate. The product can be recrystallized from ethanol/water or purified by chromatography on silica gel. This chemical can also be used as an activated nucleophile in the synthesis of spirocyclic compounds and isomeric ketones. 2-(2,4-Dinitrophenoxy)ethanol is toxic and may cause severe skin burns if it comes into contact with unprotected skin. It is also environmentally hazardous when released into the environment because it breaks down slowly and may accumulate in soil or water systems.</p>Formula:C8H8N2O6Purity:Min. 95%Color and Shape:PowderMolecular weight:228.16 g/mol11-cis-Retinol
CAS:11-cis-Retinol is a retinoid that has been synthesized in the laboratory. 11-cis-Retinol has been shown to inhibit the activity of bacterial enzymes such as signal peptide, which is involved in protein synthesis. It also inhibits the growth of bacteria by inhibiting energy metabolism and atp-binding cassette transporter. Retinoids are active against infectious diseases, including HIV, and have shown anti-inflammatory properties that may be due to their ability to suppress cytokine production. 11-cis-Retinol is used as a vitamin supplement and is applied topically to treat eye disorders.Formula:C20H30OPurity:Min. 85%Color and Shape:Yellow PowderMolecular weight:286.45 g/mol
