Description
Nickel(II) Chloride (CAS 7718-54-9, EC 231-743-0), also referred to as NiCl2 or nickel dichloride, is an inorganic nickel salt with the molecular formula Cl2Ni. It carries no assigned E-code and is classified under HS code 28273500 within the Salts & Minerals category.
In electroplating and surface finishing, NiCl2 acts as a source of nickel ions in plating baths, improving anode corrosion and deposit uniformity. In chemical synthesis and biotechnology, it functions as a Lewis acid catalyst, activating specific reaction pathways. It is also used in textile dyeing processes, where it coordinates with dye molecules to fix color onto fiber substrates.
Nickel(II) Chloride is available in powder form and is subject to REACH regulation (Regulation EC 1907/2006), with nickel compounds classified as substances of very high concern (SVHC). Procurement should confirm supplier SDS documentation and compliance declarations. Standard packaging formats include fiber drums and multi-layer bags for bulk industrial supply.
