Description

Isooctyl Hydrogen Phthalate is a specialized ester of phthalic acid, functioning as a key intermediate and plasticizer component. Its molecular structure offers a balance of solvency and compatibility, making it valuable for formulating products requiring controlled viscosity and stability. This chemical is primarily utilized by manufacturers in the polymer, coatings, and specialty chemical industries seeking reliable performance additives.

Application

• Primary intermediate in the synthesis of higher molecular weight plasticizers, such as diisononyl phthalate (DINP).
• Co-plasticizer and viscosity modifier in PVC, rubber, and other polymer formulations.
• Solvent and carrier fluid in specialty coatings, adhesives, and sealants.
• Chemical intermediate for producing esters, lubricants, and functional fluids.
• Additive in industrial lubricants and greases to enhance film strength and stability.
• Component in research and development of new polymeric materials and resin systems.

Quality Control

Our Isooctyl Hydrogen Phthalate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. Certificates of Analysis (COA) documenting purity and key specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. The container should be kept tightly sealed when not in use to minimize moisture absorption.
