Atorvastatin Impurity 53(CAS: 42558-54-3)

Atorvastatin Impurity 53, with the CAS number 42558-54-3, is a chemical compound identified as an impurity in the production of atorvastatin, a widely used statin medication for lowering cholesterol. It is typically a white to off-white crystalline solid with a molecular formula of C21H26O5 and is used primarily in pharmaceutical quality control and research to ensure drug purity and safety.

Atorvastatin Impurity 53 is mainly used in the pharmaceutical industry for the identification and quantification of impurities during the manufacturing and quality control of atorvastatin. It is also employed in research settings to study degradation pathways, stability, and the impact of impurities on drug efficacy and safety.

Atorvastatin Impurity 53 is generally considered safe when handled according to standard laboratory procedures. However, as with any chemical, it should be handled with care, using appropriate personal protective equipment (PPE) such as gloves and goggles. Safety data sheets (SDS) recommend avoiding prolonged exposure and ensuring proper disposal to meet regulatory standards.

Atorvastatin Impurity 53 should be stored in a cool, dry, and dark place, ideally at 2-8°C. It is best kept in a sealed container to prevent moisture and contamination. Avoid exposure to light and ensure storage conditions are stable to maintain its chemical integrity and purity over time.
