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.)

MeSH Entry Terms：

Diphenylcarbazide Use and Manufacturing

Methods of Manufacturing

Derived from the reaction of phenylhydrazine and urea. Phenylhydrazine and urea were added to xylene, and reacted at reflux for 32 hours, left overnight, and the crude product was filtered out. Then dissolve in the mixed acid mixed solvent of ethanol and a little acetic acid, quickly cool and crystallize, filter and wash again with ethanol, and filter to dry is the finished product.

Uses

As indicator in titrating Fe; for the colorimetric determination of Cr, detection of Cd, Hg, Mg, aldehydes, emetine.
