Laboratory Chemicals can be termed as ‘Chemicals with a specified purity and impurity limits’, used mainly as standards for evaluation of purity of other chemicals. Naturally, their main use is in analytical and quality control laboratories. Here it seems desirable to define the word ‘Reagent’. Laboratory regent can be described as a “Substance employed as a test to determine the presence of some other substance by means of the reaction which is produced”.

This means, of course, that the reagent itself must be pure and it follows that any substance used in the test must also be pure. In fact, Laboratory Chemicals have a wide range of end-uses being employed in a large variety of establishments thus making it difficult to give a precise definition.
