3-Butylphthalide Impurity 27(CAS: 502-56-7)

3-Butylphthalide Impurity 27 (CAS: 502-56-7) is a crystalline solid with a molecular weight of approximately 244.37 g/mol. It has a melting point of around 75-76°C and is slightly soluble in water but soluble in organic solvents like ethanol and acetone. It is chemically stable but can react with strong bases.

3-Butylphthalide Impurity 27 (CAS: 502-56-7) can be synthesized through the hydrolysis of 3-nitro-1,1,2,2-tetrabutoxyethane. Commonly used catalysts include sodium hydroxide, and the reaction requires basic conditions. The yield is typically around 90%, with high selectivity towards the desired impurity.

3-Butylphthalide Impurity 27 (CAS: 502-56-7) is primarily used in the pharmaceutical industry as an intermediate in the synthesis of phthalide derivatives. It may also have applications in the polymer industry for modifying polymer properties and in sensors for specific chemical detection.

When handling 3-Butylphthalide Impurity 27 (CAS: 502-56-7), operators should wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. The substance should be stored in a cool, dry area away from strong oxidizers. In case of a spill, it should be handled with a fume hood, and the incident should be reported to the safety department. For detailed safety information, refer to the Safety Data Sheet (SDS).
