CAS 131-18-0: Di-N-pentyl phthalate
Description:Di-N-pentyl phthalate (DNPP) is an organic compound belonging to the phthalate family, commonly used as a plasticizer to enhance the flexibility and durability of plastics. It is characterized by its chemical structure, which includes two pentyl groups attached to a phthalate backbone. DNPP is typically a colorless to pale yellow liquid with a low volatility and a relatively high boiling point, making it suitable for various industrial applications. It is soluble in organic solvents but has limited solubility in water, which influences its environmental behavior. DNPP is known for its low toxicity compared to other phthalates, but concerns regarding its potential endocrine-disrupting effects have led to increased scrutiny and regulation in some regions. Its applications extend to the production of flexible PVC, coatings, and adhesives. As with many phthalates, the use of DNPP is subject to ongoing research regarding its safety and environmental impact, prompting manufacturers to explore alternative plasticizers.
