Copper gluconate

Copper gluconate from Henan Sinotech Import & Export Corp. is supplied as a light blue to blue-green crystalline powder with a guaranteed copper content of 98.0 - 102.0 %. The material is produced under controlled conditions to meet food-grade and pharmaceutical purity requirements, with impurity limits set at chloride ≤ 0.07 %, sulfate ≤ 0.05 %, arsenic ≤ 3 ppm, and lead ≤ 3 ppm. These tight controls make it suitable for direct use in nutritional supplements and pharmaceutical formulations without further purification.

The compound is formed by reacting copper carbonate with gluconic acid, yielding a stable chelate that is soluble in water and slightly soluble in ethanol. Typical industry grades for this product include USP, EP, and BP standards, with a standard molecular weight of 453.84 g/mol and a CAS number of 527-09-3. For food and pharmaceutical applications, particle size is often controlled between 80 and 120 mesh, a standard range for uniform dispersion in tablets and capsules.

Primary buyers are nutraceutical manufacturers, pharmaceutical companies, and animal feed producers seeking a bioavailable copper source. The product is commonly packed in 25 kg multi-layer bags with a polyethylene liner, a standard format for bulk industrial use. Importers should confirm the supplier’s ability to provide ISO and FDA-compliant documentation, as these are critical for market access in regulated regions.
