1.5.5      On-line help – References

Where data are present, the tab “References” contains information about the chemical relations of the given substance and information about various official inventories that might include it.



If a given substance is included in an official inventory, e.g. the Danish inventory of carcinogenic substances, and the inventory is included in SPIN, then the code and title of the inventory will appear in the inventory list under the title “Inventories”. The inventories in SPIN will typically either be connected to regulation (as the Danish inventory of carcinogenic substances), science (substances with certain properties) or politics (as the Danish list of undesirable substances).



In many cases the name and a CAS-No. not only covers one specific substance, but a mixture or compound of different substances. This often proofs to be the case with polymers and isomeric mixtures, where the “substance” in reality is a sometimes inseparable mixture of substances resulting from a chemical reaction. In SPIN these “substances” are described by their chemical building blocks, the substances that reacted chemically to form the mixture, under the title “Components”. In the case below, the “substance” is propoxypropanol formed from the components 1,2-propanediol and 1-propanol.



If the isomers of the “substance” are known they will be listed under the title “References”. In the case below there is only 1 isomer: 1-propoxy-2-propanol.
