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>Formule :C12H9ClO2Degré de pureté :Min. 95%Couleur et forme :Off-White PowderMasse moléculaire :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>Formule :C8H10N2ODegré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :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>Formule :C21H18O5SCouleur et forme :Brown Red PowderMasse moléculaire :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>Formule :C8H10N2O3Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :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>Formule :C8H8N2O6Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :228.16 g/mol3’,5’-Di-O-benzoyl-2’-deoxy-2’-fluoro-5-trifluoromethyl-arabinouridine
