To make it easier to search for certain chemical substances, we have organized some of them in substance groups. For example, when searching for certain organotin compounds such as hexapentyldistannoxane, it may be helpful to search for organotin compounds instead.
Observe that there may be many substances that belong to a specific substance group but nevertheless are not included in the database. Whether these substances have PRIO characteristics, must be assessed on a case-by-case basis.
For each substance group, PRIO displays a list of substances included in that group and provides information on their uses and expected properties.
