5-Chloro-2-methyl-3-isothiazolone - Active Ingredient >14%, CMI/MI 2.5 - 4.0
CAS :<p>5-Chloro-2-methyl-3-isothiazolone (CMIT) is a highly water-soluble apoptotic agent and preservative with numerous applications. It is used in anti-microbial coatings, latex formulations, hydraulic fracturing fluids, pesticides and cosmetics. CMIT in conjunction with 2-methyl-4-isothiazolin-3-one (MIT) is marketed as Kathon. CMIT is also an allergen. CMIT is active against gram-positive and gram-negative bacteria, yeasts and fungi. CMIT is believed to form mixed disulfides with protein thiol groups which then undergo thiol-disulfide exchange reactions to give mixed protein thiol disulfides leading to cell apoptosis and necrosis.</p>Formule :C4H4ClNOSCouleur et forme :Yellow Clear LiquidMasse moléculaire :149.6 g/molMethylene violet

Produit contrôlé<p>6b-Hydroxy prednisolone is a metabolite of prednisolone. The metabolism of prednisolone to 6b-hydroxy prednisolone is catalyzed by the enzyme CYP3A4, which results in the formation of 6β-hydroxyprednisolone and a hydrogen peroxide that reacts with catalase to form water and oxygen. The conversion is dependent on the concentration of galactose, as it provides substrate for CYP3A4. If cyclosporine or other drugs are taken concurrently, they may inhibit the metabolism of 6b-hydroxy prednisolone. The kinetics of 6β-hydroxyprednisolone have been investigated in tissues and plasma samples, and it has been shown that this metabolite has a short half-life in both tissues and plasma samples. This drug can be analysed using chromatography, but endogenous substances such as cortisol can interfere with the process.</p>Formule :C21H28O6Degré de pureté :Min. 95%Couleur et forme :Light (Or Pale) Yellow SolidMasse moléculaire :376.44 g/mol9,10-Bis[2-(4-methoxyphenyl)ethynyl]anthracene

CAS :<p>Fast blue RR salt is a phosphatase inhibitor that belongs to the group of diazonium salts. It is used as an indicator for damaged cells, and it can be used in cell culture. Fast blue RR salt can also be used in biological samples for radiation detection. Fast blue RR salt has been shown to inhibit p-nitrophenyl phosphate (PNPP) phosphatase activity in erythrocytes and lymphocytes from healthy humans. The inhibition is due to the binding of the molecule to the enzyme's active site, which prevents the binding of phosphate ions. This results in a decrease in PNPP hydrolysis, leading to a build-up of PNPP and a decrease in ATP levels. Fast blue RR salt has been shown to have low energy radiation properties, making it more suitable for use with biological samples than other diazonium salts such as Fast red TR salt or Fast green BB salt.</p>Formule :C15H14CIN3O3•(ZnCl2)0Couleur et forme :PowderMasse moléculaire :491.35 g/molPigment Red 169

CAS :<p>Basic violet 3 is a light-sensitive dye that can be used for the detection of metals. It is a basic dye with a high resistance to water vapor and other solvents. Basic violet 3 has been shown to be carcinogenic in animal studies, but has not been shown to have any adverse effects on humans. The dye reacts with metal hydroxides such as aluminum hydroxide, iron(III) oxide, and calcium hydroxide by absorbing UV radiation. This reaction produces an increased amount of light that can be detected using a spectrophotometer. Basic violet 3 is used in surface methodology because it is able to react with particles and then bind to them through van der Waals forces. Basic violet 3 is also used for kinetic experiments because it provides data about the rate of chemical reactions or chemical processes. Kinetic data from these experiments can be used to determine the mechanism of the reaction or process being studied.</p>Formule :C25H30N3·C2H3O2Couleur et forme :PowderMasse moléculaire :431.57 g/mol
