Chemical groups on the SIN List
The SIN List contains about 1000 CAS numbers, quite an overwhelming figure. But many chemicals are similar in terms of chemical structure, toxicological properties and technical functions. more or less.
For many reasons it can be wise to tackle chemicals on a group level, rather than substance by substance.
The substances on the SIN List have been divided into 15 substance groups, some of which have been further divided into subgroups.
Contains phenols with lipophilic alkyl groups of at least four carbons attached to the aromatic ring with a carbon-carbon bond in the orto and para position. The aromatic ring can contain other functional groups as well. The phenol oxygen is unsubstituted or ethoxylated.
Contains compounds with two or more fused aromatic rings. The rings can be substituted with, halogen, nitro and amino groups.
Contains simple aromatic compounds.
Contains compounds in which two phenols are bridged with one carbon or heteroatom. The bridge-atom can be oxidized or substituted with hydrogen, alkyls, phenyl and esters. The phenol oxygens are unsubstituted.
Carbon nanotubes (CNTs) are cylindrical tubes of hexagonal arrangement of carbon atoms linked by a double bond. CNTs have a very high aspect ratio and their diameter can be much lower than 100 nm whereas their lengths can reach several hundred micrometers. There are different types of CNTs depending on the number of side-walls and their atomic structure in the side-walls. The simplest CNTs are single-walled (SWCNT), double-walled (DWCNT) and multi-walled (MWCNT).
Contains compounds with fluorinated alkyl chains. At least six carbons in each chain are fully fluorinated. The fluorinated chain is substituted at one end with sulphonamides, sulphonic acid, phosphates or carboxylic acid Some compounds contain unfluorinated carbons but are in this context treated as perfluorinated compounds (PFCs).
Contains ethers and esters of mono and poly 1,2-ethanediols and 2-hydroxyacetic acid. The carbon backbone can be further substituted with alkyl groups.
Contains brominated and/or chlorinated alkanes. The number of halogens is three or more, distributed over two or more carbons. At least two carbons are halogenated. There are at least one halogen/five carbons.
Contains brominated and/or chlorinated alkenes. The double bond is substituted with two or more halogens.
Contains brominated and/or chlorinated aromatic compounds with one benzene ring with at least three halogens or two or more benzene rings with at least two halogens on each ring.
Contains salts and complexes of oxidized antimony.
