What Are Reagents?
A reagent is a chemical element, compound or mixture that triggers a chain of chemical reactions when added to a system. A reagent is also used to test if a certain chemical reaction occurs. Many biochemical and industrial processes involve reagents.
A reagent may simply speed up a chemical reaction but is not consumed in the process like catalysts. In some processes, a reagent directly participates in a chemical reaction and is consumed in the process. In this case, a reagent is also a reactant.
When it comes to biochemical reactions that are aided by enzyme catalysts, the reactants are called substrates. Enzymes that serve as catalysts are also reagents.
What Are Reagents Used For?
Reagents are used either as catalysts or as reactants in synthesizing a wide range of inorganic and organic compounds. They are mainly used in industrial processes for manufacturing various products, from medicines to plastics.
Some reagents are used as chemical indicators for diagnostic testing (e.g. glucose test) and forensic investigations (e.g. luminol for detecting invisible blood splatter on surfaces). Here are some examples of common reagents and their uses:
- Acetylene – a hydrocarbon and the simplest alkyne, which is commonly used as a fuel and a chemical building block
- Ammonia – a chemical precursor used in manufacturing fertilisers
- Ammonium hydroxide – the aqueous form of ammonia traditionally used for qualitative inorganic analysis
- Azobisisobutyronitrile – commonly used as a foamer in the manufacture of plastics and rubber products
- Baeyer’s reagent – an alkaline solution of dissolved potassium permanganate. Commonly used as a qualitative biochemical test for the presence of unsaturation, such as double bonds
- Chromic acid – a very corrosive oxidising agent uses as an intermediate in chromium plating
- Collins reagent – used to selectively oxidize primary alcohols to convert into aldehyde
- Copper(I) iodide – has a wide range of applications that include synthesis of organic compounds and cloud seeding
- Dess–Martin periodinane – commonly used for oxidising primary alcohols to aldehydes and secondary alcohols
- Dicyclohexylcarbodiimide – used in artificial peptide synthesis to connect amino acids
- Dihydropyran – used as a protecting group for alcohols in organic synthesis
- Sodium hydroxide – used as an electrolyte and has several industrial applications like manufacturing detergents. It reacts with acids to form salts
- Sodium nitrite – has important biochemical application for converting amines into diazo compounds
- Sulfuric acid – most commonly used for various industrial applications as a precursor for various synthetic chemicals
- Tetrahydrofuran – a precursor for synthesising polymers
How Are Reagents Made?
Some reagents are naturally occurring and do not need to be synthesised but simply need to be purified. For instance, purified water is commonly used as a reagent in biomedical and industrial lab testing.
Some reagents like antibodies (polyclonal and monoclonal) simply need to be isolated from other biological and biochemical substances. Biological reagents are important in synthesising drugs, manufacturing vaccines, and testing for pathogens.
Industrial-grade reagents are either distilled forms of naturally occurring substances like hydrocarbons from fossil fuels or they are synthesised from existing chemicals.
