For professionals in the chemical industry, a precise understanding of product specifications is key to successful sourcing and application. Dioctyl Phthalate (DOP), also identified by its CAS number 117-81-7, is a fundamental chemical whose properties dictate its utility across numerous sectors. NINGBO INNO PHARMCHEM CO.,LTD. offers essential details for those looking to buy DOP.

Dioctyl Phthalate is typically characterized as a colorless to slightly yellow, oily liquid with a faint odor. Its purity is a critical specification, often rated at 99.5% or higher for technical grades, ensuring consistent performance in demanding applications. The density of DOP is approximately 0.986 g/cm³, and its refractive index is around 1.4852. These physical properties are crucial for quality control and for calculating formulation ratios.

The chemical formula for DOP is C24H38O4, and its molecular weight is approximately 390.55 g/mol. Its low water solubility, around 0.02 mg/L at 25°C, contributes to its effectiveness in applications where moisture resistance is important. The high boiling point, 386.9°C, indicates its low volatility, which is advantageous for maintaining product integrity over time, especially in flexible PVC applications exposed to elevated temperatures.

When considering sourcing DOP, understanding packaging and delivery terms is also vital. DOP is commonly supplied in 200kg net iron drums or 1000kg IBC tanks, with options for bulk tanker or flexitank deliveries depending on the quantity required. NINGBO INNO PHARMCHEM CO.,LTD. ensures reliable supply chains and adherence to international shipping standards.

For manufacturers and formulators, specifying the correct grade and ensuring consistent quality of DOP is paramount. Whether used as a plasticizer, solvent, or in other industrial processes, the detailed specifications provided by suppliers like NINGBO INNO PHARMCHEM CO.,LTD. are indispensable for achieving desired product outcomes and ensuring compliance with industry standards.
