The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals. Some documentation and label information may refer to the legacy brand. To solve this problem, we can put the data that we are given and that which we need to find into a table. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. A sample of cobalt(II) chloride hydrate (CoClHO) is heated until its mass remains constant. 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 complex, which is blue in color. Cobalt (II) chloride 97 CAS Number: EC Number: 231-589-4 Synonyms: Cobalt dichloride,Cobalt muriate,Cobaltous chloride,Dichlorocobalt Linear Formula: CoCl2 find Sigma-Aldrich-232696 MSDS, related peer-reviewed papers. Five hydrates of zinc chloride are known, as well as four forms of anhydrous zinc chloride. Cobalt chloride is an indicator for water in desiccants, owing to the reversible hydration/dehydration coupled with distinct color change. Packaging type: glass bottle (packaging info) Description: 50ml amber glass bottle with 40mm butress neck finish + 40mm blue cap with PTFE wad. Cobalt (II) chloride catalysed coupling of thiols and anhydrides: a new and efficient synthesis of thiol esters. 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. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.Cobalt(II) chloride is used in humidity indicator in weather instruments. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Cobalt chloride is an indicator for water in desiccants, owing to the reversible hydration/dehydration coupled with distinct color change. Other accessories, consumables and equipmentĬobalt(II) chloride is used in humidity indicator in weather instruments. The invention relates to a method for preparing anhydrous cobalt chloride by using a solvent displacement method, and relates to a preparation method for an.Date Of Print: Product Specifications are subject to amendment and may change over time. It is blue when active and pink when hydrated (Ref 1). One of the 'various forms' of cobalt chloride is Drierite, a mixture of cobalt chloride and calcium sulfate which is a common dessicant. It can be prepared by dehydration of the hexahydrate either at 150160 ☌ in vacuo.
