Product Name:Tetrabromophenol Blue (TBPB)
English Name:Tetrabromophenol Blue (TBPB)
CAS No.:4430-25-5
Aliases:Tetrabromophenol blue, TBPB, 4,5,6,7-Tetrabromo-3,3-bis(3,5-dibromo-4-hydroxyphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide
Molecular Formula:C19H6Br8O5S
Physical Properties:Beige crystalline powder. Melting point 204°C (dec.), boiling point 728.8±60.0°C (predicted), density 2.668±0.06 g/cm³ (predicted). Soluble in water, ethanol, methanol, acetone and acetic acid. pKa = 3.69 (25°C); color changes from yellow to blue over pH 3.0–4.6. UV absorption maxima at approximately 388 nm and 610 nm; extinction coefficient ≥55000 at 606–616 nm in ethanol and water. Store under inert atmosphere at room temperature.
Uses:Used as an acid-base indicator (color change from yellow to blue, pH 3.0–4.6) and protein detection reagent. It is also applied in semiconductor processing, thin films, recording materials, chemically amplified resists, photographic materials, lithographic plates, inks, toners, detergents, hair dyes, and urine analysis test strips. Additionally, it can be used to distinguish between allergies and infections.
