Avanafil Impurity 32(CAS: 53554-29-3)

Avanafil Impurity 32 (CAS: 53554-29-3) is a crystalline solid with a molecular weight of approximately 650.64 g/mol. It has a low solubility in water (0.1 g/100 mL at 25°C) and is highly soluble in organic solvents such as methanol. The compound is relatively stable under normal conditions but can degrade upon exposure to heat or light. It does not react with common reagents and is classified as a non-reactive compound.

Avanafil Impurity 32 (CAS: 53554-29-3) is synthesized through a series of organic transformations starting from a suitable precursor. Common methods include the use of Friedel-Crafts acylation and nucleophilic aromatic substitution. The synthesis involves the use of a Lewis acid catalyst, such as aluminum chloride, and proceeds with high selectivity and yield, typically greater than 95%.

Avanafil Impurity 32 (CAS: 53554-29-3) is primarily used in the pharmaceutical industry as an impurity in Avanafil, a phosphodiesterase-5 inhibitor. It is also of interest in analytical chemistry for quality control purposes and as a reference material in the development of analytical methods. While not widely used in other industries, its presence in Avanafil indicates its relevance in pharmaceutical research and manufacturing.

When handling Avanafil Impurity 32 (CAS: 53554-29-3), it is advisable to work in a well-ventilated area or fume hood to minimize inhalation of dust. Use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Avoid skin contact and ingestion. In case of spillage, immediately clean up the area using appropriate absorbent materials and report to the safety officer. Always refer to the safety data sheet (SDS) for detailed information on handling and disposal.
