Phenol Red Sodium Salt (Water Soluble) is a high-purity pH indicator commonly used in cell culture media, biochemical research, and diagnostic applications. This water-soluble form ensures easy and consistent integration into aqueous solutions, providing reliable colorimetric changes across a pH range of 6.8 (yellow) to 8.2 (red). It is ideal for monitoring pH fluctuations in biological systems, laboratory testing, and environmental analysis. With excellent stability and solubility, Phenol Red Sodium Salt is suitable for sensitive applications where precision and consistency are essential. Available in a range of standard and custom packaging sizes, this compound meets the quality standards required for research, analytical, and industrial use.

Bromophenol Blue Sodium Salt (Water-Soluble) is a high-purity pH indicator dye widely used in analytical chemistry, biology, and laboratory diagnostics. It is a sulfonephthalein dye that appears as a dark purple to reddish-brown powder and is freely soluble in water. The compound has a molecular formula of C₁₉H₉Br₄NaO₅S and a molecular weight of approximately 691.85 g/mol. Bromophenol Blue exhibits a distinct pH color transition from yellow at pH 3.0 to blue at pH 4.6, making it ideal for use in acid-base titrations, electrophoresis tracking, and as a general pH indicator in various buffer systems. It is also used in protein and nucleic acid staining protocols. This sodium salt form enhances solubility in aqueous solutions, making it easy to prepare indicator solutions or integrate into assay workflows. The product is typically supplied with high dye content (≥90%) and low moisture content, ensuring consistent performance. It should be stored in a tightly closed container in a cool, dry place. Standard safety precautions apply, as the compound may cause irritation to the skin, eyes, and respiratory tract upon prolonged exposure.

Its used as an intermediate for manufacturing clomiphene citrate & anti UV for plastics , poymer & textiles.
