FAQs
What is lignin?
Lignin is a complex organic polymer that forms a major structural component of plant cell walls, giving plants rigidity. This alkaline grade is a chemically processed lignin derived from natural sources, supplied as a black solid, and is used in research and materials applications rather than extracted fresh by the user.
What does the alkaline grade mean?
Per the manufacturer, the alkaline lignin (L0082) has been adjusted into an alkaline pH range and is more water-soluble than the corresponding dealkaline lignin grade. The improved water solubility can make it easier to work with in aqueous systems for research and formulation purposes.
What is the CAS number?
The LabPro listing gives CAS number 8061-51-6 for this alkaline lignin, with MDL number MFCD00135572, and notes it is TSCA listed. Confirming the CAS number helps ensure you receive the correct lignin grade and lets you cross-reference the Safety Data Sheet for handling information.
What is lignin used for in research?
Lignin and its derivatives are studied and used across materials science, including as dispersants and binders and in research into renewable feedstocks and bio-based materials. As a naturally derived polymer, it is of ongoing interest for sustainable chemistry and materials development.
What sizes are available?
The material is offered in 25 g and 500 g pack sizes. Choosing a size close to your expected usage helps manage cost and storage. The smaller size suits exploratory or small-scale work, while the larger size is more economical for higher-volume research.
