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.

Lignin is one of the most abundant biopolymers in nature and has great potential to be transformed into high-value chemicals. However, the limited availability of molecular structure data hinders its potential industrial applications. Structural data were generated using a sequence-controlled polymer generation approach that was calibrated to match experimental lignin properties. The LGS dataset is a valuable resource to advance lignin chemistry research, including computational simulation approaches and predictive modelling.

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.

Harmonised classification and labelling is a legally binding classification and labelling for a substance, agreed at European Community level. It does not represent a new labelling, classification or hazard statement, neither reflect other factors that affect the susceptibility of the effects described, such as duration of exposure or substance concentration e.
