As identifier you may enter a cas number, a molecular formula or a name. A query will be done in the ChemExper Chemical Directory (https://www.chemexper.com) and a window will pop-up showing possible products. By cliking on the product, the window will close and the identifier will be replaced by the corresponding cas number. If this is an unknown product, please use the cas number as identifier. If is does not exist, leave this field blank.
The molecular formula may be entered the way a chemist thinks about it. You may use groups like Ph, Me, Et, Ala, Gly, ... For example if you want the molecular formula of isobutyryl chloride you may simple enter Me2CHCOCl. Using ChemCalc (https://www.chemcalc.org) the molecular weight will be suggested to you.
The purity may be entered as % (percent in weight), M (molar, mmoles/ml) or L (loading, mmoles/g).
This table shows all the reagent required to synthesize 10 mmoles of the target compound.
The maximum score for the yield is 50. It is calculated by dividing the yield by 2.
For hazard, the maximum score is 20. Each reagent being extremely flammable, toxic, explosive or dangerous for environnement leads to a lost of one point (per hazard). A highly toxic (T+) reagent yields to a lost of 2 points.
