Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. More information about the EC Inventory can be found here. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. If generated, an InChI string will also be generated and made available for searching. More help available here. CAS no.

Lignin cas

Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. Chemically, lignins are polymers made by cross-linking phenolic precursors. Lignin was first mentioned in by the Swiss botanist A. It is one of the most abundant organic polymers on Earth , exceeded only by cellulose and chitin. Lignin is present in red algae , which suggest that the common ancestor of plants and red algae also synthesised lignin. This finding also suggests that the original function of lignin was structural as it plays this role in the red alga Calliarthron , where it supports joints between calcified segments. The composition of lignin varies from species to species. An example of composition from an aspen [8] sample is Lignin is a collection of highly heterogeneous polymers derived from a handful of precursor lignols. Heterogeneity arises from the diversity and degree of crosslinking between these lignols.
