Apremilast Impurity 28(CAS: 253168-94-4)

Apremilast Impurity 28 is a chemical compound identified as an impurity in the pharmaceutical drug apremilast. With the CAS number 253168-94-4, it is typically a byproduct of the synthesis process. Its exact chemical formula and structure are not widely published, but it is characterized as a low-molecular-weight compound with specific physical properties relevant to pharmaceutical quality control. It is not intended for therapeutic use but plays a role in ensuring the purity and safety of apremilast.

Apremilast Impurity 28 is primarily used in pharmaceutical research and quality control to identify and analyze impurities in apremilast, an inhibitor of phosphodiesterase 4 (PDE4). It may also be studied for its potential impact on drug efficacy or safety. While not used in food or industrial applications, it is relevant in drug development for compliance with regulatory standards and ensuring product consistency. Its role is limited to analytical purposes in the production of apremilast.

Apremilast Impurity 28 is generally considered low risk when handled properly, but safety precautions should be followed as with any chemical. Limited toxicity data exists, but it is advisable to use personal protective equipment (PPE) such as gloves and goggles during handling. Regulatory guidelines recommend avoiding ingestion, inhalation, or skin contact. While not intended for human use, its safety profile is assessed in the context of pharmaceutical impurity standards to ensure it does not compromise the safety of the parent drug.

Apremilast Impurity 28 should be stored in a cool, dry place away from light to maintain stability. It is typically kept in sealed, airtight containers to prevent contamination. Storage conditions should align with those of apremilast, such as controlled temperature (usually 2-8°C) and humidity levels. Avoid exposure to moisture or heat, and ensure proper labeling to distinguish it from the active pharmaceutical ingredient (API).
