An examination of chlorpromazine hydrochloride as indicator and spectrophotometric reagent for the determination of molybdenum(V)

Analytica Chimica Acta, 1977
Abstract Chlorpromazine hydrochloride (CPA) has been tested as indicator in the titration of molybdenurn(V) with cerium(IV)sulphate at room temperature in sulphuric acid medium. It gives a sharp, reversible colour change from colourless to dark-red at the equivalence point.

Singlet Oxygen in Plants—Its Significance and Possible Detection with Double (Fluorescent and Spin) Indicator Reagents

Photochemistry and Photobiology, 2006
ABSTRACTDirect detection of reactive oxygen species (ROS), especially singlet oxygen, in plants under stress conditions is of special importance, not only to identify primary events of oxidative damage, but also in studies exploring the potential role of ROS as signal molecules.

Using Silica Gel Beads to Dispense Indicators and Reagents

Journal of Chemical Education, 1995
Silica gel beads which have adsorbed certain chemical reagents such as acid-base indicators, detecting reagents, color-producing metal ions, and organic dyestuffs can be used in classrooms and field studies either as teaching aids or for students' laboratory work.

Examination of metallochromic indicators and water-soluble reagents for metals by planar electrophoresis

The Analyst, 1986
Water-soluble azo, phthalein, sulphonphthalein and anthraquinone indicators and reagents were subjected to low-voltage electrophoresis on cellulose acetate sheets at pH 2–12. All dyes except low-sulphonated azo dyes yielded one or more sharp bands showing good mobility and resolution over some range of pH values.
