For chemists, formulators, and procurement specialists, a deep understanding of a chemical's properties is fundamental to its effective application. Dibutyl Phthalate (DBP), a prominent ester with the CAS number 84-74-2, is characterized by a unique set of physical and chemical attributes that dictate its behavior and utility across various industries. As a leading supplier of DBP, NINGBO INNO PHARMCHEM CO.,LTD. provides insights into these critical properties.

Dibutyl Phthalate is chemically known as the diester of phthalic acid and n-butanol. Its molecular formula is C16H22O4, and it possesses a molecular weight of approximately 278.34 g/mol. Physically, it presents as a colorless to pale yellow, oily, and viscous liquid. Key physical properties include a boiling point of around 340°C, a melting point of -35°C, and a density of approximately 1.043 g/mL at 25°C. Its refractive index, n20/D, is typically around 1.492, and it has a flash point of 340°F (171°C), indicating it is combustible but requires significant heat to ignite.

In terms of reactivity, DBP is an ester, which means it can undergo hydrolysis under acidic or alkaline conditions, breaking down into phthalic acid and n-butanol. It is generally stable under normal storage conditions but should be kept away from strong oxidizing agents, strong acids, and strong bases to avoid potentially vigorous reactions. Its low vapor pressure at ambient temperatures means it is not highly volatile, contributing to its utility in applications where prolonged performance is needed.

The solubility profile of Dibutyl Phthalate is also important. It is very soluble in most organic solvents such as alcohol, ether, and acetone, but only slightly soluble in water. This characteristic influences its use as a solvent and its behavior in multiphase systems. For professionals looking to buy Dibutyl Phthalate, understanding these properties is key to successful formulation and safe handling.

When considering DBP for your industrial needs, procuring it from a reputable Dibutyl Phthalate manufacturer in China ensures you receive a product that meets stringent purity specifications. Inquiring about the Dibutyl Phthalate price from trusted suppliers like NINGBO INNO PHARMCHEM CO.,LTD. allows for cost-effective sourcing of this versatile chemical. Familiarizing yourself with the detailed specifications and safety data sheets available from manufacturers is a crucial step for any R&D scientist or procurement manager.
