Froehde reagent
REAGENT USED AS A SIMPLE SPOT-TEST TO PRESUMPTIVELY IDENTIFY ALKALOIDS
Froehde's reagent; Froehde Reagent
The Froehde reagent is used as a simple spot-test to presumptively identify alkaloids, especially opioids, as well as other compounds. It is composed of a mixture of molybdic acid or a molybdate salt dissolved in hot, concentrated sulfuric acid, which is then dripped onto the substance being tested.
Fehling's solution
REAGENT USED FOR ANALYSIS OF SOLUTION
Fehling solution; Fehling's Solution; Fehling's reagent; Fehling reagent; Fehling test; Fehling's test; Fehling's Reagent; Bistartratocuprate(II)
Fehling's solution is a chemical reagent used to differentiate between water-soluble carbohydrate and ketone functional groups, and as a test for reducing sugars and non-reducing sugars, supplementary to the Tollens' reagent test. The test was developed by German chemist Hermann von Fehling in 1849.

Dithiothreitol
Dithiothreitol (DTT) is the common name for a small-molecule redox reagent also known as Cleland's reagent, after W. Wallace Cleland. DTT's formula is C4H10O2S2 and the chemical structure of one of its enantiomers in its reduced form is shown on the right; its oxidized form is a disulfide bonded 6-membered ring (shown below). The reagent is commonly used in its racemic form, as both enantiomers are reactive. Its name derives from the four-carbon sugar, threose. DTT has an epimeric ('sister') compound, dithioerythritol (DTE).
