Chemical reagents are fundamental components for conducting experiments, tests and analyses in the fields of science and research. Their proper use is crucial to ensure accurate results, as well as maintaining safety in the laboratory environment. As not all reagents are the same, their classification is indispensable for understanding their properties, risks, and the best way to handle them.

In this article, we will discuss the classification of chemical reagents used in the laboratory, with the aim of optimising analytical processes and preventing accidents as much as possible. At DC Fine Chemicals, as fine chemical suppliers, we know how important it is to be informed before carrying out any chemical reaction, so we invite you to continue reading this article before purchasing any of our products.

What are chemical reagents?

Chemical reagents are compounds that combine to cause a chemical reaction or analyse the composition of other substances. Most reagents seek a specific reaction when used, whether it be a colour change or the detection of a substance, among others.

The idea of chemical reagents is that they are controlled in a safe space such as the laboratory. Each reagent has its particular properties and applications, although there are different ways in which they can be classified, whether by their degree of purity, their danger, their use or their origin.

Classes of chemical reagents according to their use

Before inducing a chemical reaction, it is important to know the purpose of the reaction and the opportunities it offers:

  • Analytical reagents: These are used to carry out precise chemical analyses. Their main characteristic is their level of purity, as they must contain minimal impurities so as not to interfere with the results of the analyses. At DC Fine Chemicals, you can find different analytical reagents for your laboratory.
  • Synthesis reagents: These are used to produce new chemical compounds through chemical reactions. An example is hydrochloric acid (HCl) which is used for the synthesis of chlorides or copper sulphate (CuSO₄) which is used in the synthesis of other copper compounds.
  • Biochemical reagents: These are used specifically for experiments in biology and biochemistry.

Responsible use of chemical reagents

Even knowing the reactions and the use that can result from mixing chemicals, if the correct measures are not maintained, the practice can have negative impacts on the environment and human health. In order to avoid these risks, there are a number of guidelines for using chemical reagents safely. We will explain them below:

  • Reduce the quantity: A large amount of substances is not usually necessary to induce a chemical reaction. For this reason, it is important to control and analyse alternative reagents before wasting resources.
  • Good storage: The chemical product must be stored under appropriate conditions of both temperature and humidity. In addition, it must be in the indicated container and with a label to avoid confusion.
  • Proper disposal: Each reagent must be separated and disposed of safely. To do this, the corresponding regulations and instructions must be followed. If you do not know the disposal method, you can consult companies specialising in the disposal of hazardous waste, but never dispose of samples down the drain.
