Product Specifications
Thymol Blue is an organic chemical compound with the chemical formula C₂₇H₃₀O₅S and CAS Number 76-61-9. Also known as Thymolsulfonephthalein, it is commonly supplied as a greenish-brown to reddish-brown crystalline powder. It is sparingly soluble in water but dissolves in alkaline solutions and certain organic solvents.
Thymol Blue is valued for its distinct colour transitions across two pH ranges, making it a useful indicator in analytical chemistry. It changes from red to yellow over approximately pH 1.2–2.8 and from yellow to blue over approximately pH 8.0–9.6. These colour changes allow it to be used in acid-base titrations, pH testing, preparation of indicator solutions, and laboratory experiments involving acid-base reactions.
Its indicator properties make Thymol Blue useful in analytical chemistry, inorganic chemistry, educational experiments, and general laboratory research. Different grades and purities are available, and the appropriate grade and preparation method should be selected according to the requirements of the intended application.
KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.
Safety Note: Thymol Blue should be handled carefully to avoid generating or inhaling airborne dust. Dust may cause irritation to the eyes, skin, and respiratory tract. Avoid direct contact with the eyes and skin and use appropriate personal protective equipment when handling the material. Handle it in a suitable, well-ventilated area and follow the supplier's Safety Data Sheet (SDS) for proper handling, storage, and disposal.
