![]() ![]() 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. CoSO 4 + Ba (ClO 3) 2 BaSO 4 + Co (ClO 3) 2. Cobalt chloride hexahydrate is an excellent water soluble crystalline Cobalt source for uses compatible with chlorides. It is formed by a double displacement reaction between cobalt (II) sulfate and barium chlorate, barium sulfate precipitates and cobalt chlorate can be crystallized out of the filtrate. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Cobalt (II) chlorate is a chemical compound with the formula Co (ClO 3) 2. 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. 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. Often, as your gut health increases so does your ability to eat a variety of foods without overreacting.Cobalt(II) chloride is used in humidity indicator in weather instruments. You might need to limit high-cobalt foods at the beginning. Either way, when we collaborate on a Mineral- Nutritional Balancing Program one of the goals is to strengthen gut health. Or it’s something you’ll realize when we do an initial assessment. You might already know that cobalt is affecting your health in some way. Metabolism and toxicokinetics Gastro-intestinal absorption of radiolabelled cobalt dichloride in rats varied between 11 and 34, depending on the dose. ![]() By slowly adding the foods back in, you can pinpoint which ones are your Some people don’t react to all the foods listed above, only some of them. If a low-cobalt diet resolves your symptoms, you can reintroduce foods one by one (one per week) to see how you react to them. In some people, they need to take it one step further by avoiding oral ingestion of cobalt by eliminating certain foods. If you’ve been diagnosed with a cobalt allergy or instructed to avoid cobalt by a healthcare professional, treatment consists of avoiding all contact with items containing cobalt. Because cobalt and nickel allergy are so closely related, a patient should always be patch tested for nickel as well, although pure nickel and cobalt test solutions are difficult to obtain. Based on the skin’s response to the patch, a cobalt allergy is either confirmed or ruled out. Because the reaction takes two or three days to become visible, the patch is left in place for up to 72 hours. Patch testing involves applying a patch containing the test substance (in this case, 2% cobalt chloride) to the patient’s back. One study found that nickel-sensitive patients with dyshidrotic eczema simultaneously developed a cobalt allergy and patients with simultaneous nickel and cobalt allergies had more severe dyshidrotic eczema.Ī cobalt allergy is typically diagnosed by conducting a thorough medical evaluation, studying the patient’s history, and conducting a patch test. Cobalt allergy often coexists with nickel allergy in many people, increasing the severity of symptoms. Fluid-filled blisters on soles of feet and/or palms of hands (dyshidrotic eczema)ĭiagnosing a cobalt allergy can be a bit tricky due to its association with nickel.Symptoms of an allergic reaction to cobalt may include: Today, we’re going to discuss cobalt allergy and what you should do if you suspect you have it. Some people, however, develop an allergy to cobalt, requiring them to avoid certain items and foods. When these animals consume cobalt, bacteria in their stomachs transform cobalt into cobalamin- more commonly known as vitamin B12-which is needed by all animals and humans. Cobalt is needed for the health of ruminant animals, such as cows and sheep. It is typically found in combination with another metal, nickel, as separating the two metals is too costly. Cobalt is a metal commonly found in soil, seawater, and various industrial compounds. ![]()
