Description

Copper Sulphate Pentahydrate Powder

Here is a compound that does not pretend to be something it is not.

Copper Sulphate Pentahydrate is not a "gentle" mineral. It is not "highly bioavailable" in the way that chelated amino acid complexes are. It is, however, remarkably useful - provided you understand what it is for.

This bright blue crystalline powder has been known for centuries. Alchemists called it blue vitriol. Modern chemists call it CuSO₄·5H₂O. We call it a reliable source of copper for applications where purity and consistency matter more than marketing claims.

Let us be direct: this is not the form you would choose for a premium multivitamin. There are better, gentler options for direct human supplementation. But for animal nutrition, agricultural use, industrial applications, and certain technical formulations, Copper Sulphate Pentahydrate is the standard. It is stable, water‑soluble, and economical.

Think of it as the work boot of copper compounds: not elegant, but exactly right for certain jobs.

Benefits of Copper Sulphate Pentahydrate Powder

01Essential Copper Source for Livestock

Copper is a required trace mineral in animal feed. This form provides a concentrated, bioavailable source for cattle, poultry, swine, and aquaculture. Animals need copper. This delivers it.

02Fungicide & Agricultural Use

Copper sulphate has been used as a fungicide for over a century. Remains effective against certain plant diseases, particularly in vineyards and orchards. (Bordeaux mixture, containing copper sulphate, is historically significant for a reason.)

03Industrial Catalyst & Reagent

Used in electroplating, pigment production, and various chemical syntheses. A reliable oxidizing agent and source of copper ions for solution chemistry.

04Water Treatment Algaecide

Used to control algae in reservoirs and water systems. At appropriate concentrations, it is effective. Hence the need for careful dosing and regulatory compliance.

05Mineral Supplement in Technical Formulations

Used in certain industrial and research applications where copper is required as a nutrient or catalyst - not for direct human consumption in raw form.

06Economical & Reliable

Cost‑effective and widely available. The work boot of copper compounds: not elegant, but exactly right for certain jobs.

Application Fields

Animal Feed Premixes: The largest application by volume. Added to mineral premixes for cattle, poultry, swine, and fish. Essential for growth, immune function, and connective tissue health.
Agricultural Fungicides: Used in crop protection, particularly for grapes, potatoes, and vegetables. Often formulated with lime (Bordeaux mixture) or other adjuvants.
Industrial & Technical Applications: Electroplating baths, pigment manufacturing (e.g., copper phthalocyanine), textile dyeing, and chemical synthesis.
Water Treatment: Algicide for reservoirs, ponds, and cooling towers. Requires precise dosing and regulatory compliance.
Laboratory Reagent: Used in analytical chemistry, educational laboratories, and research settings. The bright blue color makes it immediately identifiable.

FAQ

Q1: Is Copper Sulphate Pentahydrate safe for humans to take directly?

A: Generally, no. Not in raw powder form. It is an irritant and can cause nausea and vomiting. For human supplementation, use chelated forms like copper bisglycinate or copper gluconate. This product is intended for animal feed, agriculture, and industrial use - not for dropping directly into a smoothie.

Q2: Why is it blue?

A: The pentahydrate form contains water molecules coordinated around the copper ion. These water molecules absorb light in the orange‑red part of the spectrum, leaving blue to be reflected. Chemistry is not magic, but it can look like it.

Q3: What is the difference between pentahydrate, monohydrate, and anhydrous?

A: Water content. Pentahydrate has five water molecules per copper sulphate unit. Monohydrate has one. Anhydrous has none. The pentahydrate is the most common and stable form under normal conditions.

Q4: Can this be used in organic farming?

A: It depends on the certification body. Copper sulphate is permitted in some organic farming systems as a fungicide, though usage is often restricted due to environmental persistence. Check your local regulations - we sell ingredients, not legal advice.

Q5: How should it be stored?

A: In a cool, dry place, in sealed containers. It is hygroscopic to a degree and can cake if exposed to humidity. Also, keep it away from children and anyone who might mistake bright blue powder for candy. (It is not candy.)

Q6: What is the typical dosage in animal feed?

A: Varies by species and age. For cattle: 10–30 ppm in total ration. For poultry: 5–15 ppm. For swine: 10–20 ppm. These are general ranges. Work with a qualified animal nutritionist for precise formulation.

Q7: Does it dissolve completely in water?

A: Yes, readily. Solubility is approximately 200 g/L at room temperature. The solution will be blue and clear. If it is not clear, you have impurities or incomplete dissolution.

Q8: Is this product GMO‑free?

A: It is a mineral compound. It contains no genetic material of any kind. The question does not technically apply, but if you need a certificate stating it is GMO‑free, we can provide one.
