Cobaltous Chloride Hexahydrate, identifiable by CAS 7791-13-1, functions as a hydrated inorganic salt used primarily as a visual humidity indicator in desiccants and a cobalt source in surface treatment. Chemically defined as Cobalt(II) Chloride Hexahydrate, these deep red to purple deliquescent crystals serve as a critical component in electroplating baths for depositing cobalt-alloy coatings and as a precursor for synthesizing organocobalt complexes. The substance, often referred to as Cobalt Chloride 6H2O in technical catalogues, acts as a chemical sponge that changes color from red to blue upon dehydration, signaling moisture saturation in silica gel applications. We facilitate bulk supply of this inorganic compound with competitive factory pricing, capable of meeting customized specifications for crystal size and insoluble matter, backed by comprehensive MSDS, TDS, COA documentation.

FAQ - Technical & Supply Chain
-
Q:
Do cobaltous chloride hexahydrate and cobalt(II) chloride hexahydrate refer to the same substance?
A: Yes. They are different naming conventions for the same hydrated cobalt chloride compound and correspond to the same CAS number. -
Q:
Is cobaltous chloride hexahydrate used as a source of cobalt in formulated systems?
A: Yes. It is commonly used where cobalt is required as a trace element within controlled formulation systems. -
Q:
Does the hexahydrate form represent a different chemical identity from anhydrous cobalt chloride?
A: Yes. The hexahydrate and anhydrous forms have different hydration states and are assigned different CAS numbers, although they share the same cobalt chloride framework.
