PHOSPHORUS TRICHLORIDE FOR SYNTHESIS
Phosphorus trichloride is a precursor to PCl5 and a few other phosphorus compounds, which is used in many applications, including herbicides, insecticides, oil additives, flame retardants, etc. It is used directly as a reagent in organic…
PONCEAU S FOR ELECTROPHORESIS
Ponceau S is a anionic dye commonly used for the detection of electro- blotted proteins after an electrophoretic separation prior to Western blotting [12–14] or MALDI-MS analysis [15].Ponceau S Staining Solution is supplied as ready to…
PHENOL RED INDICATOR SOLUTION
Phenol red is a water-soluble dye used as a pH indicator, changing from yellow to red over pH 6.6 to 8.0, and then turning a bright pink color above pH 8.1. As such, phenol red can be used as a pH indicator dye in various medical and cell…
PHOSPHORUS PENTOXIDE AR
Phosphorus pentoxide is a deliquescent compound prepared by reacting phosphorus with air. It is a commonly used as dehydrating and condensing agent in organic synthesis.
POLYVINYL ALCOHOL
Polyvinyl alcohol (PVOH, PVA, or PVAl) is a synthetic polymer which is both colourless, odourless and water-soluble. It was initially discovered in the early 1920's and since has been used in numerous applications from the lamination of…
POLYVINYL PYRROLIDONE PVP
Polyvinylpyrrolidone, also known as povidone or PVP, is used in the pharmaceutical industry as a synthetic polymer vehicle for dispersing and suspending drugs.N-vinyl-2-pyrrolidone (VP) is commonly used as a reactive diluent for radiation…
PHENOL RED AR pH indicator
Phenol red is a water-soluble dye used as a pH indicator, changing from yellow to red over pH 6.6 to 8.0, and then turning a bright pink color above pH 8.1. As such, phenol red can be used as a pH indicator dye in various medical and cell…
PHOSPHORUS PENTAOXIDE FOR SYNTHESIS
Phosphorus pentoxide is a potent dehydrating agent as indicated by the exothermic nature of its hydrolysis P4O10 + 6 H2O → 4 H3PO4 (–177 kJ). A granular form of P4O10 is used in desiccators. Consistent with its strong desiccating power,…
POLYPHOSPHORIC ACID FOR SYNTHESIS
Synthesis and composition The basic compounds for the production of polyphosphoric acid (PPA) are phosphorus pentoxide (P2O5) and phosphoric acid (H3PO4), as shown in Figure 2. Phosphorus is first oxidized to phosphorus pentoxide, which…
PHENOL CRYSTAL
Phenol crystals are used to describe the solid forms that result from the phenol compound, which is also known as the carbolic acid. ... It is an extremely volatile white crystalline solid that is mildly acidic. It requires extremely…
POLYETHYLENE GLYCOL 6000
The reason for for using PEGs with large molecular weight is that smaller PEGs can diffuse through the cell wall and are even taken up by plant cells and distributed through the plant, which may influence the results. larger than 6,000…
PHOSPHORUS OXYCHLORIDE LR
Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula POCl3. It hydrolyses in moist air releasing phosphoric acid and fumes of hydrogen chloride. It is manufactured industrially on a large…
