1. Product Overview & Specifications

Didecyl Phthalate (CAS 84-77-5), also known as Di-n-decyl phthalate, is a high-performance plasticizer and gas chromatographic stationary phase. Key parameters include:

2. Applications & Industrial Uses

Primary Applications:

• Gas Chromatography: Stationary phase for selective separation of aromatic compounds, unsaturated hydrocarbons, and oxygen-containing compounds (alcohols, aldehydes, ketones).
• Plasticizer: Enhances flexibility and durability in vinyl resins, cellulose polymers, and high-temperature-resistant plastics (e.g., cables, automotive interiors).

Advantages Over DOP:

• 75% lower volatility
• Superior migration resistance
• Extended thermal stability (up to 150°C)
