Cobalt dichloride9/2/2023 It contains cobalt in its +2 oxidation state. Not included are any expedited or LTL shipments or dIrect shipped items from Spectrum vendors or manufacturers which are charged at published carrier rates. Cobalt(II) chloride, also known as cobaltous chloride and cobalt dichloride, is a chemical compound. There are some additional charges that are item specific. offers a flat fee shipping when items are shipped “directly from Spectrum warehouses” by regular UPS ground within the contiguous United States. (View landing page for Print/Download version of this information.) Please read our MaIMPORTANT UPDATE and ApIMPORTANT UPDATE about receiving shipments during coronavirus-related crisis. Cobalt(II) chloride should be stored in an airtight container or bag to counter its strong hygroscopic nature. 1).Firstly, there is a modified tetrapyrrole that ligands a central cobalt ion. The chlorine atom has a covalent radius of 1024 pm and its Van der Waals radius is 175 pm. Its electron configuration is Ne3s 2 3p 5. Chlorine is a Block P, Group 17, Period 3 element. Eye and hand protection should be worn while handling this compound. The structure of vitamin B 12 can be considered in three parts (Fig. The origin of the word Cobalt comes from the German word 'Kobalt' or 'Kobold,' which translates as 'goblin,' 'elf' or 'evil spirit. Synonym (s): Cobalt dichloride, Cobalt muriate, Cobaltous chloride, Dichlorocobalt. Lab Nucleic Acid Purification Equipment Cobalt dichloride is a strong allergen, with a LD 50 of 80 mg/kg (rats). AnhydroBeads, 10 mesh, 99.9 trace metals basis.Lab Centrifuges- Stirrers- Shakers and Vortexers.Laboratory Meters and Testing Equipment.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 ) fluoride Cobalt acetate tetrahydrate Cobalt acetate Cobalt amino sulfonate Cobalt bromide ( ous ) Cobalt chloride Cobalt dibromide Cobalt. Therefore, in accordance with Le Chatelier’s principle, when the temperature is raised, the position of the equilibrium will move to the right, forming more of the blue complex ion at the expense of the pink species. Disposal of cobalt chloride would be a problem if you had 15 kilos of it, not 15 grams. Cobalt chloride can be prepared in aqueous solution from cobalt(II) hydroxide or cobalt(II) carbonate and hydrochloric acid: 1. (aq) CoCl (aq) + 6H O (l) is endothermic. 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. The best way to dispose 15 grams of CoCl2 is to throw it out of the window or flush down the toilet. We recently designed a series of NNP and PNP pincer cobalt catalysts that are effective for stereodivergent semihydrogenation of alkynes to (E)- and (Z)-alkenes (Scheme 1) 11.This catalytic system exhibits excellent stereoselectivity when a specific dichloride cobalt pincer complex is used with no over-reduction products of the alkenes. 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.
