Searches for a chemical component based on a range of its formula mass (in g/mol).
The minimum or maximum value for the molecular weight range may be left unspecified in
which case only the provided end of the range is used.
Enter "Between 300 and 310" and the results will all chemical components
with molecular weight equal or more than 300 and equal or less than 310 g/mol like for example "018" with molecular weight 302.27 g/mol.
Enter "Between 1000 and leave the upper bound unspecified.
This will result in all chemical components with molecular weight more than 1000 g/mol like "0CR"
with molecular weight 1423.50 g/mol.
Leave lower bound unspecified and enter 60 for the upper bound. The results will be all chemical components with
molecular weight less than 60 g/mol like "3CN" (3-AMINOPROPANE) with molecular weight 59.11 g/mol
