Cobalt dichloride9/6/2023 Whereas the anhydrous dichloride is blue, the hydrate is red. Chloride compounds can conduct electricity when. Cobalt is a chemical element with the symbol Co and atomic number 27. In addition to supplying several cobalt chloride compounds in a variety of amounts and purities, Noah Tech also offers custom chemical services to customers all over the country.įor more information on our industry-leading quality assurance program or to order CoCl 2 directly, please reach out to Noah Tech today. Cobalt Chloride is an excellent water soluble crystalline Cobalt source for uses compatible with chlorides. These are inorganic compounds in which the largest halogen. Noah Chemicals’ on-staff chemists are happy to talk with you about the role cobalt (II) chloride plays in your process. Cobaltous chloride belongs to the family of Transition Metal Chlorides. Surface treating metal is another common industrial use of the compound. It is also used for electroplating, particularly for plating objects with cobalt metal. Cobalt (II) chloride is said to be kinetically inert.Ĭommercially, cobalt (II) chloride is often used to make sealants, adhesives, and glues. It’s a necessary precursor for both cobaltocene and tetralykl. Uses advised against Food, drug, pesticide or biocidal product use. A common precursor to other cobalt compounds, CoCl 2 is readily oxidizes and often used in the presence of a catalyst. Product Name Cobalt(II) chloride, anhydrous Cat No. It’s also a powerful intermediate compound. Cobalt (II) chloride is a weak Lewis acid. It’s often used as an indicator for water desiccants. Diesel Fuel (20, 30, 40, 50) A Diethyl Ether (ethyl ether, ether) B. Noah Chemicals supplies cobalt (II) chloride anhydrous with 99% purity in several amounts.Ĭobalt chloride changes color in response to humidity, hence the color differential between its anhydrous and hexahydrate forms. Dichloroethylene B Dichloroisopropyl Ether. It is generally supplied in bead form and should be handled carefully as it is a suspected carcinogen. The amount of Cobalt chloride in silica gel balls would be absolutely harmless. The only situation in which cobalt poisoning is a serious problem is when it is exposed directly to your bloodstream (Recently it has been an issue with people who have undergone certain hip implants - see this page). Noah Chemicals supplies ACS Reagent grade cobalt (II) chloride hexahydrate.Ĭobalt (II) chloride anhydrous, also known as Cobaltous Chloride, is a beautiful sky blue color. Cobalt poisoning is apparently very rare. Hexahydrate is by far one of the most common forms of cobalt used in laboratory settings. Harmful if swallowed or applied directly to skin, it is generally shelf-stable at room temperature. The chemical formula for the compound is CoCl 2 ♶H 2 O. The hexahydrate of cobalt (II) chloride is bright pink. The compound is most often supplied as cobalt (II) chloride hexahydrate or as cobalt (II) chloride anhydrous. Its chemical formula is CoCl 2 and its molecular weight is 129.833 g/mol. 2 Classification in accordance with Regulation (EC) No 1272/2008 Annex VI, part 3, Table 3. The Cobalt Dichloride humidity indicator card is available in the standard JEDEC required format indicating 5, 10 and 60% RH, a 6 spot 10-60% RH Card (similar to the AEC826004NE) and a 4 spot 10-40% RH Card (similar to the HM-04 HIC).Cobalt (II) chloride is one of the most common forms of chloride found the lab today. Cobalt dichloride pentahydrate CAS number: 2 Cobalt dichloride hexahydrate CAS number: Cobalt dichloride hydrate (3:22) CAS number: 14 Cobalt dichloride decahydrate CAS number: 7. The Humitector CDF provides verifiable color-change accuracy as required by JEDEC standard J-STD-033B, as well as exceeds applicable regulations administered by the ECB. Some companies have expressed the desire to begin using a Cobalt Dichloride Free humidity indicator card. Meet European Chemical Bureau (ECB) REACH directivesĬobalt Dichloride Free Humidity Indicator Cards offer the electronics and semiconductor industries a Cobalt Dichloride (CoCl2) Free humidity indicator (HI) card, while maintaining the accuracy required by international JEDEC standards.Ĭobalt Dichloride Free Humidity Indicator Cards provide electronic and semiconductor manufacturers with a JEDEC compliant humidity indicator card that is free of Cobalt Dichloride, a chemical regulated under European Chemical Bureau (ECB) REACH directives.
