• A naturally derived polymer: Lignin is a complex organic polymer that is one of the main structural components of plant cell walls, giving wood and other plant tissue much of its rigidity. This alkaline grade from TCI (catalog L0082) is a chemically processed lignin derived from natural sources, supplied as a black solid. As one of the most abundant natural polymers on earth, lignin is of enduring interest both as a material in its own right and as a renewable feedstock for greener chemistry.
  • What the alkaline grade offers: 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. Improved water solubility makes the material easier to work with in aqueous systems, which is helpful for researchers preparing solutions or dispersions and for formulators exploring lignin as a dispersant, binder, or component of bio-based materials.
  • Verified identity: The LabPro listing gives CAS number 8061-51-6 and describes the material as a black solid with MDL number MFCD00135572, and it is TSCA listed. Confirming these identifiers helps ensure the correct lignin grade is received, which matters because lignins differ in their processing, sulfonate and carboxyl content, and solubility, and those differences affect how the material behaves in a given application.
  • Research uses and handling: Lignin and its derivatives are studied and used across materials science, including as dispersants and binders and in ongoing research into renewable feedstocks and bio-based materials. As with any reagent, the Safety Data Sheet should be reviewed before handling, and the material stored per the manufacturer's guidance. Its naturally derived origin and abundance keep it a compound of active interest for sustainable chemistry and materials development.
