This classification covers chemical reagents and solvents used in manufacturing research and development, quality control, and analytical operations. It includes surface treatment agents for metal processing, solvents for resin molding, cleaning solvents for mechanical parts, standard reagents for quality inspection, organic solvents for analysis, pH adjustment solutions, buffer solutions, and indicators. It targets chemical products necessary for material analysis, product inspection, and process control in manufacturing sites, excluding laboratory equipment and measuring instruments. The focus is on high-purity products corresponding to precision analysis in manufacturing, such as JIS standard products, reagent grade chemicals, and HPLC solvents, with industrial chemicals equipped with Safety Data Sheets (SDS) as the main target.
