Usage & Core Function of δ-Valerolactone CAS 542-28-9
(A Multi-Functional Intermediate from Corncob Biomass)
- Pharmaceutical Intermediate
During the synthesis of high-value compounds such as pyranidine and cilostazol, Bio δ-Valerolactone serves as a highly reactive precursor to promote efficient therapeutic compound manufacture.
- Polymer Raw Material
Serves as a monomer/co-monomer to make biodegradable polyesters as well as polyurethanes, increasing flexibility and thermal stability in end uses.
- Flavour and Fragrance Ingredient
Is a precursor to cyclic esters to prepare fruity and creamy fragrance materials, usable for premium-grade fragrance preparation.
Solvent and Coating Application
With very good solvency and stability, Bio δ-Valerolactone is ideal for application as a specialty solvent system, adhesive, and industrial coatings with performance and safety.
- Water-Based Coating Dispers
Due to its favorable reactivity and good polarity, δ-Valerolactone can act as an aqueous coating dispersing aid to advance pigment dispersion, film formability, and environmentally responsible low-VOC formulations.
- Water-Based Coating Dispers
