Used in analytical chemistry for the determination of metal ions such as iron(III), copper, and cobalt through colorimetric and spectrophotometric methods. It forms intensely colored complexes with these metal ions, enabling precise quantification. Also employed in titrations, such as the Volhard method for halide determination involving precipitation of silver thiocyanate. Utilized for calibration of analytical instruments requiring accurate thiocyanate concentrations. Suitable for quality control in environmental testing (e.g., heavy metals in water), industrial processes, and research laboratories.
