3-Methylbutyl pentyl phthalate(CAS: 776297-69-9)

3-Methylbutyl pentyl phthalate (CAS: 776297-69-9) is a clear, colorless liquid with a molecular weight of approximately 296.43 g/mol. It has a high solubility in organic solvents like acetone, toluene, and chloroform. Chemically, it is relatively stable but can react with strong bases. It has a melting point of around -30°C and a boiling point of about 260°C. Due to its chemical structure, it exhibits moderate reactivity in esterification reactions.

3-Methylbutyl pentyl phthalate (CAS: 776297-69-9) is usually synthesized through a esterification reaction involving phthalic anhydride and a mixture of 3-methylbutyl alcohol and pentanol. Commonly used catalysts include sulfuric acid or tetra-n-butylammonium hydrogen sulfate. The reaction is carried out at elevated temperatures (around 100°C) under mild pressure conditions, leading to high yield and selectivity.

3-Methylbutyl pentyl phthalate (CAS: 776297-69-9) is utilized in various industries, including pharmaceuticals for solubilizing poorly soluble drugs, polymers for enhancing plastic properties, and as a fragrance and flavoring agent. It also finds application in the formulation of adhesives, sealants, and coatings due to its solvating and plasticizing properties.

When handling 3-Methylbutyl pentyl phthalate (CAS: 776297-69-9), it is essential to wear appropriate personal protective equipment (PPE), including safety goggles, gloves, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to prevent inhalation of vapors. Spills should be immediately contained and cleaned up using appropriate absorbent materials. Refer to the Safety Data Sheet (SDS) for specific handling and disposal instructions. Storage should be at room temperature away from heat sources and incompatible materials.
