What it is / When to use

Blue crystal copper source for agricultural formulations

RunziChem supplies agricultural-grade Copper Sulphate from China as copper sulphate pentahydrate (CuSO4·5H2O, 98%, ~25% Cu, blue crystal, CAS 7758-99-8) for agricultural use and fertilizer raw-material workflows. It ships in 25/50 kg export bags, jumbo bags, and custom packaging, with CAS details, TDS, batch COA and SDS for buyer review.

  • What it is Copper sulphate pentahydrate.
  • When to use Use it where a copper sulphate raw material is specified, and compare EDTA micronutrients when the route needs chelated copper.
  • Honesty note specifications are typical for evaluation; final values are confirmed per batch COA.

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?
EDTA-Cu within RunziChem EDTA Chelated Micronutrients is the choice for foliar and fertigation programs that need chelated, pH-stable copper, while copper sulphate pentahydrate (CuSO4·5H2O, ~25% Cu, CAS 7758-99-8) suits blending or basal supply where a sulphate copper raw material is specified. Confirm crop, rate, and local label rules before application.
