This tool allows to generate a list of molecular formulas based on a mass range.
Allowed Molecular Formula range in the format Xn-mYo-p (ex. C1-10H1-15B2):
The number of insaturations can be taken into account if only the following elements are allowed : H, C, O, N, F, Cl, Br, I. It is defined as ((2*nC - nH - nCl- nF - nI - nBr + nN) / 2) +1. Limit the results by unsaturations: to
Allow only integer unsaturation values:
