Calcium Sulphate

Calcium Sulphate is a common laboratory and industrial chemical. It is also used as a coagulant. Calcium sulfate is a common component of fouling deposits in industrial heat exchangers.Calcium sulfate can be used to make calcium tablets and it is used to cure brittle nails, weak hair, yellow teeth, frequent muscle cramps, joint pains, constant fatigue, kidney stones, PMS, gallstones, and high cholesterol.

Chloranilic acid is an organic compound. It is used as an laboratory reagent.

Properties Suppliers
Chlorophenol Red

Chlorophenol red is an indicator dye that changes color from yellow to violet in the pH range 4.8 to 6.7.

Properties Suppliers
Diacetyl Dioxime

Dimethylglyoxime is used in the analysis of palladium or nickel.It is used as a solution in ethanol.

Properties Suppliers

Diisopropylamine is a secondary amine. It can be dried by distillation over potassium hydroxide or drying over sodium wire or sodium hydride followed by distillation under N2 into a dry receiver. Diisopropylamine is used for the synthesis of diisopropylethylamine, by reaction with diethyl sulfate.

Properties Suppliers

Dithioerythritol is a sulfur containing sugar derived from the corresponding 4-carbon monosaccharide erythrose. It is an epimer of dithiothreitol(DTT). Like DTT, DTE makes an excellent reducing agent, although its standard reduction potential is not quite as negative, i.e., DTE is slightly less effective at reducing than DTT, presumably because steric repulsion of its OH groups makes the cyclic disulfide-bonded form of DTE less favorable. In DTT, these hydroxyl groups are on opposite sides of the ring, whereas they are on the same side of the ring in DTE.

Ethidium Bromide

Ethidium bromide is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis.Its core heterocyclic moiety is generically known as a phenanthridine, an isomer of which is the fluorescent dye acridine.Ethidium bromide is commonly used to detect nucleic acids in molecular biology laboratories. In the case of DNA this is usually double-stranded DNA from PCRs, restriction digests.Ethidium bromide is not regulated as hazardous waste at low concentrations,but is treated as hazardous waste by many organizations.

Ferrous Chloride

Ferrous chloride has a high melting point, paramagnetic solid, usually obtained as an off-white solid. It crystallizes from water as the greenish tetrahydrate, which is the form that is most commonly encountered in commerce and the laboratory. Ferrous chloride has a variety of niche applications, but the related compounds ferrous sulfate and ferric chloride enjoy more applications. Aside from use in the laboratory synthesis of iron complexes, ferrous chloride serves as a reducing flocculating agent in wastewater treatment, especially for wastes containing chromate. It is the precursor to hydrated iron(III) oxides that are magnetic pigments. Ferrous chloride is employed as a reducing agent in many organic synthesis reactions.

Gibberellic Acid

Gibberellic acid is a hormone found in plants. It is a simple gibberellin, promoting growth and elongation of cells. It affects decomposition of plants and helps plants grow if used in small amounts, but eventually plants develop tolerance for it. Gibberellic acid is sometimes used in laboratory and greenhouse settings to trigger germination in seeds that would otherwise remain dormant. It is also widely used in the grape-growing industry as a hormone to induce the production of larger bundles and bigger grapes, especially Thompson seedless grapes, and in the Okanagan and Creston Valley it is used in the cherry industry as a growth regulator.

Grignard Reagent

Grignard reagents are named after their discoverer, French chemist Victor Grignard, who jointly received the 1912 Nobel Prize for Chemistry. Grignard reagent: R-Mg-X ; R= any alkyl or aryl group , Mg= magnesium metal and X= any halogen.It is prepared by adding an alkyl halide to magnesium shavings in diethyl ether or tetrahydrofuran.It is strong bases, they add to epoxides and carbonyl groups, and used to make other organometallic reagents by reacting with metal-halogen bonds. They have wide applications in synthetic chemical industry.
