Molecular Weight

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.

Example:

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
