Cobalt Chloride Supplier in Malaysia
- Also known as
- cobalt(II) Chloride
- Cobaltous Chloride
- Cobalt Dichloride
- CoCl2
Cobalt chloride supplier enquiries in Malaysia cover cobalt(II) chloride, also called cobaltous chloride, cobalt dichloride or CoCl2. The common solid form is the hexahydrate, which is pink to red, while anhydrous cobalt chloride is a blue crystalline solid.
Technical, reagent, hexahydrate and anhydrous grades are selected by hydration state, cobalt basis and impurity limits. The colour change is a useful sign of hydration, but the specification and formula basis should decide the grade used in a process or solution.
Manufacturers use cobalt chloride in catalyst and cobalt-compound chemistry, while metal-finishing, electronic-material and humidity-indicator formulations may require a defined salt. It can also be specified as a cobalt source in mineral premixes, subject to the buyer's formulation requirements.
Send the hydration state, grade, specification, quantity and delivery location with your enquiry. Availability, packing, documentation, route and timing are confirmed with the quotation, and supply is subject to applicable requirements.

Cobalt Chloride grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Technical cobalt chloride hexahydrate | pink to red crystals or crystalline powder | — | General cobalt salt, catalyst and process chemistry where the soluble hexahydrate and a technical impurity profile are specified. | Packing format is confirmed with the quotation. |
| Anhydrous cobalt chloride | blue crystalline solid or powder | — | Synthesis, materials and humidity-indicator work where water of crystallisation cannot be carried into the process and anhydrous CoCl2 is specified. | Packing format is confirmed with the quotation. |
| Reagent grade cobalt chloride hexahydrate | pink to red crystalline powder | — | Analytical reagent, standard-solution and research work requiring tighter purity or impurity limits than a general technical grade. | Packing format is confirmed with the quotation. |

Common questions about cobalt chloride
Why are cobalt chloride hydrate and anhydrous grades different colours?
Cobalt chloride hexahydrate is commonly pink to red, while anhydrous cobalt chloride is blue because the hydration state changes the coordination around the cobalt ion. State the form required by the process rather than selecting a grade by colour alone.
Is cobalt chloride the same as cobalt sulphate?
No. They are different cobalt salts with different anions and process behaviour. Cobalt chloride is selected when the chloride counter-ion and the specified hydrate are wanted, while cobalt sulphate has its own grade and impurity requirements. Order the salt named by the formulation.
Which cobalt chloride form suits laboratory solution work?
The hexahydrate is commonly used to prepare aqueous solutions, but a method may specify anhydrous cobalt chloride or a particular reagent grade. Provide the formula basis, purity, concentration and quantity required so the quote is matched to the analytical method.
Can cobalt chloride be requested for mineral premixes?
Yes, enquiries can identify cobalt chloride as the cobalt source for a mineral premix where the buyer's feed specification calls for it. State the grade, cobalt basis, quantity, intended formulation and any applicable documentation requirement with the enquiry.
What specifications should be included in a cobalt chloride quotation?
Give the hydration state, grade, cobalt basis, assay or impurity limits, physical form, quantity and delivery location. Add the catalyst, finishing, feed, indicator or laboratory application so the suitable form is considered.
How should cobalt chloride be stored?
Keep the crystals or powder sealed in a dry store and protect them from contamination or unintended moisture exchange. Follow the safety information supplied with the quoted grade and the buyer's workplace handling procedure.
