Reagent for the sulfate color reaction test compliant with the Japanese Pharmacopoeia for pharmaceutical impurity testing.
Our "Color Comparison Solution" is prepared by mixing solutions of several inorganic salts, known as "Color Comparison Concentrate," in a specific ratio to achieve the designated color. We have adopted a 100mL low-capacity type suitable for small-scale solution preparation, which eliminates the possibility of contamination. Additionally, the preparation is in accordance with the Japanese Pharmacopoeia, and the label displays the expiration date. The sulfuric acid suitable for the color reaction test is already prepared at the required concentration. This product is diluted to comply with the concentration ranges of the Japanese Pharmacopoeia, United States Pharmacopeia, and JIS (K 0072).
