Aripiprazole Impurity 1(CAS: 120004-79-7)

Aripiprazole Impurity 1 is a white to off-white solid with a molecular weight of approximately 349.4 g/mol. It has a melting point of around 115-118°C. This impurity is slightly soluble in water and has low solubility in common organic solvents like methanol and acetonitrile. It is stable under normal storage conditions but may react with strong oxidizers. Precise solubility and reactivity data are necessary for proper handling in chemical processes.

Aripiprazole Impurity 1 is typically synthesized through a series of steps involving reactions such as amide formation, reduction, and cyclization. Catalysts like palladium and bases like potassium carbonate are often used. The synthesis involves multiple steps and requires careful temperature control to ensure selectivity and yield, typically around 80-90%. Detailed reaction conditions and purification methods are essential for obtaining high-purity impurity samples.

Aripiprazole Impurity 1 is primarily used in the pharmaceutical industry as an intermediate in the synthesis of the antipsychotic drug aripiprazole. It is also of interest in research for its potential use as a reference material in quality control processes. Some related industries that may use this impurity include chemical research and development labs, and contract manufacturing organizations (CMOs) involved in the production of pharmaceuticals.

When handling Aripiprazole Impurity 1 (CAS: 120004-79-7), it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a laboratory coat. Ensure that all handling takes place in a well-ventilated area or a fume hood to prevent inhalation of dust. Use appropriate spill containment materials and follow proper disposal procedures as outlined in the Safety Data Sheet (SDS). Always refer to the latest SDS for specific handling and storage guidelines.
