3-Butylphthalide Impurity 10 (3-propylidenephthalide)(CAS: 17369-59-4)

3-Butylphthalide Impurity 10, also known as 3-propylidenephthalide (CAS: 17369-59-4), is a secondary impurity found in 3-butylphthalide. It is a colorless or white crystalline substance with a melting point around 55-57°C. It is a derivative of phthalide with a butyl group attached to the propylidene carbon.

3-Butylphthalide Impurity 10 is primarily used in pharmaceutical applications as a raw material. It is also used in the research and development of new drug compounds and as a reference substance for quality control.

3-Butylphthalide Impurity 10 is generally considered safe under normal handling and storage conditions. However, it should be handled with care and stored in a well-ventilated area. Direct contact with skin or ingestion should be avoided. Proper personal protective equipment (PPE) should be used when handling the compound.

3-Butylphthalide Impurity 10 should be stored in a cool, dry place away from direct sunlight and heat sources. The storage temperature should not exceed 25°C. It should be kept in a tightly sealed container to protect it from moisture and light. The container should be labeled clearly and stored out of reach of children and unauthorized personnel.
