Cobalt (II) chloride anhydrous for synthesis. Make the pink cobalt chloride solution up to 100 cm 3 with 60 cm 3 concentrated hydrochloric acid from a measuring cylinder. A reddish-pink, approximately 0.4 M solution will be formed, which should be labelled as TOXIC. With strong technical force, we constantly innovate and produce excellent products, and through high-quality and efficient service, we are determined to make progress and promise to keep our reputation. Dissolve about 4 g of cobalt(II) chloride-6-water in 40 cm 3 of water in a beaker. Claims of the formation of tri- and tetrahydrates have not been confirmed. ![]() The compound forms several hydrates CoCl 2·nH 2O, for n 1, 2, 6, and 9. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.A professional design and development team keeps Nickel Sulfamate, 13478 00 7, Cobalt updated with the times, we not only set up multiple inspection steps for product quality control, but also set production standards.The company will continue to forge ahead to higher goals and make due contribution to the rational use of Cobalt Chloride Anhydrous for mankind. Cobalt(II) chloride hydrate 99. Cobalt(II) chloride is an inorganic compound of cobalt and chlorine, with the formula CoCl 2. Some documentation and label information may refer to the legacy brand. Cobalt chloride is usually supplied as the cobalt chloride hexahydrate CoCl2♶H2O, which is one of the most commonly used cobalt compounds in the laboratory. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Cobalt (II) chloride is used in humidity indicator in weather instruments. Cobalt(II) chloride catalyzes cross coupling of aryl halides or vinyl halides with aryl grignard reagents in excellent yields. Cobalt chloride is useful for producing invisible ink as it turns blue when heated and becomes invisible once it gets cooled. Cobalt chloride is an indicator for water in desiccants, owing to the reversible hydration/dehydration coupled with distinct color change. Cobalt(II) chloride anhydrous (CoCl 2) can be used as a catalyst in organic synthesis for the transformation of the various functional groups.For example, synthesis of esters via cleavage of ethers by acyl chlorides acylation of alcohols and amines by anhydrides and regioselective cleavage of oxiranes. In the anhydrous form, it finds use in electroplating of cobalt, in organic chemistry and is a precursor to cobaltocene, (bis(cyclopentadienyl)cobalt(II), which is a good reducing agent.
