产品详情

产品名称:

o-Cresolphthalein

别名:

Ortho-Cresolphthalein; Cresolphthalein; 3',3''-Dimethylphenolphthalein; BRN 0310554; 3,3-Bis(4-hydroxy-3-methylphenyl)-2-benzofuran-1(3H)-one

产品描述:

o-Cresolphthalein is a reversible pH indicator that is colorless at pH 8.2 and red at pH 9.8. The kinetics of the reverse pathway (red-purple to colorless) is slow, thereby making it an appropriate molecule to check flow patterns in ducts with corrugated walls. It is also used for the colorimetric determination of calcium content via the o-cresolphthalein complexone method. Binding of calcium to o-cresolphthalein, in the presence of alkaline conditions (pH 10-12), results in the formation of a red complex with an absorbance at 570-575nm. Spectral data: UV-Visible (lambdamax) 566 nm, 381 nm (2nd). This compound is applied in sensors, display device, imaging materials, authentication system for secure documents, lithium cells, inks, markers, toners, paints, adhesives, food storage, urine analysis test strips, drugs and blood analysis.
