| Sodium Thiosulphate | Sodium thiosulphate is an inorganic compound that's made up of sodium and thiosulfate ions. It typically exists as a white solid and has the chemical formula Na2S2O3ยท Sodium thiosulphate is often used in the photographic sector to dissolve silver halides. It's also used as an alternative to cyanide in gold extraction, although the large quantities required tend to make it more expensive option. The substance can be harmful if swallowed. Uses: Analytical chemistry, water treatment. Group: Laboratory Chemicals. Alternative Names: Sodium Thiosulphate Anhydrous. CAS No. 7772-98-7. Pack Sizes: 2.5L. | Chemicals.co.uk |
| Polyethyleneimine, linear | Polyethylenimine (PEI) or polyaziridine is a polymer with repeating unit composed of the amine group and two carbon aliphatic CH2CH2 spacer. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups. Totally branched, dendrimeric forms were also reported. PEI is produced on industrial scale and finds many applications usually derived from its polycationic character.Linear PEI fragment Typical branched PEI fragment PEI dendrimer generation 4. Uses: Used to produce polyethyleneimine and other organic chemicals; used in the paper, textile, petroleum, lacquer, cosmetic, and photography industries. Group: Pharmaceutical. Alternative Names: Aziridine, homopolymer; Ethylenimine, polymers; Montrek 1000; Polymin FL; Tydex 12; PEI 1120; PEI 18; Montrek 6; CF 218 (polymer); PEI 6; Polyaziridine; PEI 100. CAS No. 9002-98-6. Pack Sizes: 250 mg. Product ID: B1370-356807. Molecular formula: (C2H5N)x. Mole weight: 25,000 Da. Custom synthesis is available. Send your inquiries for more information. |  London |
