Bromocresol Green Sodium Salt (Water-Soluble) is a high-quality pH indicator dye used extensively in chemical analysis, biochemistry, and laboratory testing. With the molecular formula C₂₁H₁₃Br₄NaO₅S and a molecular weight of approximately 698.0 g/mol, this water-soluble compound appears as a dark green to blackish powder and readily dissolves in water to form a clear, colored solution. It exhibits a sharp pH transition from yellow at pH 3.8 to blue at pH 5.4, making it suitable for acid-base titrations, buffer preparations, and quality control procedures. Additionally, it is used in clinical chemistry for albumin assays and in microbiology for culture media formulations. The sodium salt form improves solubility and handling in aqueous systems. This product is typically supplied with high purity (≥90%), low moisture content, and consistent dye strength. It should be stored in a tightly sealed container in a cool, dry environment. As a laboratory reagent, appropriate personal protective equipment should be used during handling due to its potential to cause irritation on contact or inhalation.
