Hydrogen Suppression in Cheminformatics

ConclusionHydrogen suppression has a long history in chemistry and cheminformatics. In cheminformatics, hydrogen suppression takes two forms: virtual hydrogens and implicit hydrogens. Whereas a virtual hydrogen is represented by an explicit value, an implicit hydrogen count must be computed using a valence model. Many systems support both virtual and implicit hydrogens. To avoid errors, it's crucial to understand which form of hydrogen suppression is in play before attempting to use a toolkit or file format.
