Buyer FAQ

Copper Sulphate questions

What is the chemical identity of RunziChem Copper Sulphate?
It is copper(II) sulphate pentahydrate, formula CuSO4·5H2O, CAS 7758-99-8, also called blue vitriol. It is a blue crystalline, water-soluble copper salt with a molecular weight of about 249.69 g/mol. Copper content is typically around 25% by stoichiometry, confirmed per batch COA.
How much copper does it contain, and is the spec guaranteed?
Copper content is about 25% by the pentahydrate stoichiometry, useful for buyer screening only. The final assay, copper content, appearance, and purity are confirmed on the current batch certificate of analysis (COA), not guaranteed from the website. Request the current COA before contracting.
What physical forms and particle sizes are available?
RunziChem offers copper sulphate as blue crystal, fine 200-500 mesh micro-powder for faster dissolution and absorption, and granular grades for basal or blending workflows. Specify your preferred form and any mesh requirement, and the export team confirms availability and the matching specification.
Should I use copper sulphate or EDTA-chelated copper?
Use copper sulphate pentahydrate where a sulphate copper raw material is specified for blending or basal supply. For fully soluble fertigation or foliar routes that need chelated, pH-stable copper, compare EDTA-Cu within RunziChem EDTA Chelated Micronutrients. Confirm crop, rate, and local label rules before application.
