· CuCl2

Copper(II) chloride (CuCl2) is an inorganic ionic compound and metal halide that exists primarily as a dihydrate in industrial applications. It serves as a precursor material and process chemical in electrochemistry, metallurgy, and organic synthesis rather than as a structural engineering material. The compound is valued in industries including printed circuit board fabrication (copper etching), water treatment, photography, and wood preservation, where its strong oxidizing properties and copper ion availability make it the preferred choice over alternative chloride salts.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
