5% alpha-napthol in absolute ethanol
In the Voges-Proskauer test, the indicator used to determine glucose or lactose fermentation is alpha-naphthol and potassium hydroxide (KOH). These reagents react with the acetoin produced during the fermentation process, resulting in a pink or red color change if the organism is positive for acetoin production.
Other compounds that can be used as a reagent for the test include resorcinol, phenolphthalein, and 4-nitrophenol. These compounds can react with aldehydes to form colored products, making them useful for qualitative tests for the presence of aldehydes.
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.

Molisch test reagent is composed of alpha-naphthol dissolved in ethanol.
No, patchoulol is used in perfumery.

Barritt's reagent A contains potassium hydroxide (KOH) and Barritt's reagent B contains alpha-naphthol and concentrated sulfuric acid. Both reagents are used in the biochemical identification of bacteria, specifically for distinguishing between oxidase-positive and oxidase-negative bacteria.
Other compounds that can be used as a reagent for the test include resorcinol, phenolphthalein, and 4-nitrophenol. These compounds can react with aldehydes to form colored products, making them useful for qualitative tests for the presence of aldehydes.
Nope! I live there! Although it is closed to certain people, (boys, for example, cannot enter any part of the house above the ground floor) the members of Alpha Xi Delta still live there. It was recently renovated to prepare for our centennial.
Alpha Phi Alpha
principle of molisch's testIt's based on the dehydration of the carbohydrate by sulfuric acid to produce an aldehyde, which condenses with two molecules of α-naphthol,resulting in appearance of a purple ring at the interface between the acid and test layers.
