Drug Information

MeSH：

Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant and Hackh's Chemical Dictionary, 5th ed, p301, p499) (See all compounds classified as Indicators and Reagents.)

Glyoxal bis(2-hydroxyanil) Use and Manufacturing

Methods of Manufacturing

It is derived from the reaction of o-aminophenol and glyoxal. Dissolve o-aminophenol in water, add sodium sulfonate, filter at 80°C and add glyoxal dropwise to react. Cool, filter the precipitate, wash with water, recrystallize with methanol, and dry in vacuum to obtain the finished product.

Uses

Complexation indicator. Used for the determination of calcium, cadmium, aluminum and uranium. Photometric determination of calcium, erbium, indium, scandium, ruthenium, yttrium.
