Phenol Red is an organic chemical compound with the molecular formula C₁₉H₁₄O₅S. Also known as Phenolsulfonphthalein, it is a pH indicator commonly used in laboratory analysis, cell culture, microbiological testing, and analytical chemistry. It exhibits characteristic colour changes from yellow under acidic conditions to red near neutral pH and pink under alkaline conditions.
Product Specifications
Phenol Red is an organic compound with the molecular formula C₁₉H₁₄O₅S and CAS Number 143-74-8. It has a molecular weight of approximately 354.38 g/mol and is commonly supplied as a red or reddish-brown crystalline powder. It is used as a pH indicator due to its characteristic colour response across different acidity and alkalinity levels.
Phenol Red is valued for its reliable pH-indicating properties and versatility in laboratory applications. Common applications include preparation of pH indicator solutions, monitoring pH changes in cell culture media, microbiological testing, biochemical research, and analytical chemistry procedures. Its colour transition generally occurs across a pH range of approximately 6.8 to 8.2, changing from yellow to red and then pink as alkalinity increases.
Phenol Red is also used in biological research and educational laboratories where monitoring changes in acidity or alkalinity is important. The appropriate grade and purity should be selected according to the requirements of the intended application, particularly for cell culture and microbiological work.
KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.
Safety Note: Phenol Red is generally considered to have low toxicity under normal laboratory handling conditions. However, dust may cause irritation to the eyes, skin, and respiratory tract. Avoid unnecessary inhalation of dust and direct contact with the eyes and skin. Wear suitable personal protective equipment, including safety glasses, protective gloves, and appropriate laboratory clothing. Handle in a well-ventilated area and minimise dust generation. Store in a tightly closed container in a cool, dry place, protected from moisture and incompatible substances. Follow the supplier's Safety Data Sheet (SDS) for proper handling, storage, and disposal.
