Used primarily as a plasticizer in polyvinyl chloride (PVC) and other polymers to improve flexibility and durability. It is commonly found in coatings, adhesives, sealants, and elastomers where resistance to heat and UV degradation is required. Its hydroxyl functional group allows for better interaction with polar matrices, enhancing compatibility and performance in specialty applications such as medical devices and automotive parts. Also investigated for use in stabilizing formulations where improved migration resistance is needed.
