Primepure™ – High-Purity Solvents by Kanto Chemical
At Kanto Chemical, we uphold the highest standards in chemical manufacturing, and our Primepure™ series exemplifies this commitment. Primepure™ is our line of high-purity solvents, specially engineered for critical applications that demand exceptional cleanliness and consistency.
Formulated with ultra-low levels of metal impurities (over 20 elements) and minimal organic contaminants, Primepure™ solvents offer industry-leading purity for use in semiconductor processes, analytical laboratories, and other high-precision environments.
Ultra-High Purity
Primepure™ solvents are refined using Kanto Chemical’s proprietary purification technology. Each element is controlled at the parts-per-billion (ppb) level or lower, making Primepure™ among the purest solvent products available on the market today.
Guaranteed Quality – Over 30 Items
We guarantee ultra-low metallic impurities (over 20 elements), all maintained below ppb levels. Additionally, in solvents like acetone, we ensure the reduction of specific organic contaminants such as 4-Hydroxy-4-methyl-2-pentanone (Acetone Dimer) for greater stability and performance.

Ultrapur™ – Ultra-High Purity Acids and Alkalis for Trace Metal Analysis
Ultrapur™ is Kanto Chemical’s premium lineup of ultra-high purity acids and alkalis, engineered specifically for instrumental trace metal analysis at the parts-per-trillion (ppt) level. As modern analytical techniques such as ICP-MS and ICP-AES evolve, detection limits have advanced from ppb (10⁻⁹) to ppt (10⁻¹²), increasing the demand for reagents with exceptionally low metal impurity levels.
Ultrapur™ products are formulated to meet these rigorous demands, ensuring metal impurities remain below 10 ppt, delivering unmatched performance for ultra-trace analysis.
Ultra-Low Impurity Levels
Refined using Kanto’s proprietary purification processes in cleanroom environments, Ultrapur™ reagents contain undetectable to minimal levels of metal impurities—typically at or below the ppt level—making them among the purest acids and alkalis available for analytical use.
Contamination-Free Packaging
To prevent contamination from conventional containers, Ultrapur™ products are packaged in high-quality PFA (Teflon®)-coated bottles, eliminating risks associated with materials like glass.
Traceable Quality with Certificate of Analysis
Each Ultrapur™ product is supplied with a lot-specific Certificate of Analysis (CoA), detailing trace impurity levels as verified by ICP-MS and AAS methods, ensuring full transparency and traceability.
