 #### Giving the amount of chemicals as a product of a reaction 
-The yield of a product of a reaction is given for pure products. If the product is gained as crude compound (due to whatever reason) this has to be clearly given in the form: "crude product was gained". The yield of a reaction should be given in weight, mmol/mol and percentage in parentheses after the compound name (or its equivalent). The informqtion in parentheses is separated by a comma. 
-Valid options are: 
-(a) Methyl quinoline-4-carboxylate (16.4 g, 87.5 mmol, 76% yield) was isolated as a colorless solid.
-(b) Methyl quinoline-4-carboxylate (16.4 g, 87.5 mmol) was isolated as a colorless solid in 76% yield.
-(c) Methyl quinoline-4-carboxylate was isolated as a colorless solid in 76% yield (16.4 g, 87.5 mmol).

+If the product is gained as crude compound which was not purified this has to be clearly given in the form: "crude product was gained". If the compound was obtained with impurities, the impurities have to be mentioned in the analyses of the characterization of the sample, and the impurities have to be included to the yield of the reaction by changing the purity/concentration value of the sample. In such a case, please mention the correction of yield in the deacription as follows (example a)): <br/>

 :::caution Change in sample required
-Information on the purity of a product need to be added in the sample entity of the repository
+Information on the purity of a product need to be added in the sample entity of the repository. A purity of 90% corresponds to a the value of 0.9 in the field concentration of a sample.
