You need to know some common examples of reagents and their reaction

A reagent is basically a compound or mixture which is added to a system to create a chemical reaction or test if a reaction occurs. A reagent helps to tell whether or not a specific chemical substance which is present in the system by causing a reaction to occur with it. The biochemical reagents can be a compound or mixture. Inorganic chemistry, most of the biochemical reagent products are small organic molecules or inorganic compounds. These reagents are used for various medication and analytical test. Here are some examples of reagents and their reactions are described below:

Grignard reagent

The Grignard reagent is a chemical compound which is prepared by reaction of an organohalogen with magnesium in a nitrogen atmosphere because this reagent reacts very much with the oxygen and moisture. The presence of organohalogen varies greatly in their rates of reaction with magnesium. It was named after the French Chemist Francois August's Victor Grignard and it was published in 1900. This is one of the common reagents what is widely used in the world.

Tollents’ reagent

Tollents’ reagent is basically a chemical reagent which is used to know the presence of aldehyde, aromatic aldehyde, and alpha hydroxy ketone functional groups. This is another common reagent which comes after the Grignard reagent. It is called as Tollents’ reagent from the name of Bernhard Tollents’ who invented it. The positive test with tollents’ reagent often produces a characteristic silver mirror on the inner surface of the reaction vessel. You can get this tollents’ reagent from the Biochemical Reagents Manufacturers.  This reagent consists of a solution of silver nitrate, ammonia, and some sodium hydroxide.

Fehling solution

Fehling solution is a chemical reagent which is used to differentiate the water-soluble carbohydrate and ketone, functional groups. But you need to know that this biochemical reagent products or solution has a drawback which cannot differentiate between benzaldehyde and acetone. It was developed by German chemist Hermann von Fehling on 1849. Basically, this is a test which is conducted to reduce sugars and non-reducing sugar. You can say this is supplementary to the tollents' reagent.

Collins reagent

Collins reagent is the complex of chromium oxide with pyridine in dichloromethane. It was developed in 2002 by using formula one Technology. You can use this reagent to selectively oxidize primary alcohols to the aldehyde and it can tolerate many other functional groups within the molecule. This type of reagent is widely available to the Biochemical Reagents Manufacturers.

Fenton's reagent

Fenton's reagent is basically a solution of hydrogen peroxide with ferrous iron which is used to oxidize contaminants and wastewater. Basically, this reagent destroys organic compounds such as trichlor and tetrachloroethylene. It was developed in 1980 by Henry John and used as an analytical reagent. 

These all are examples of reagents. You can find this type of reagent from the manufacturer of reagents products. But before using this reagent, you must know all the uses and reaction of these components.
