Acitretin EP Impurity A (Acitretin USP Related Compound A, 13-cis-Acitretin)(CAS: 69427-46-9)

Acitretin EP Impurity A, also known as Acitretin USP Related Compound A or 13-cis-Acitretin (CAS: 69427-46-9), is a crystalline compound with a molecular weight of approximately 314.37 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and methanol. Chemically, it is relatively stable under normal conditions but can react with strong acids and bases. It is important for pharmaceutical applications due to its structural similarities to the main compound, acitretin.

Acitretin EP Impurity A is typically synthesized via a stereocontrolled pathway that involves the transformation of acitretin into its 13-cis isomer. This process often utilizes chiral catalysts to ensure high stereoselectivity. The synthesis usually involves protecting groups, hydrolysis, and reductive amination steps. The overall yield is around 70-80%, making it a feasible and industrially viable process.

Acitretin EP Impurity A (CAS: 69427-46-9) is primarily used in the pharmaceutical industry. It is a key intermediate in the synthesis of acitretin, a drug used to treat psoriasis. While it is not directly used in other industries like polymers or semiconductors, its structural similarity to acitretin makes it valuable for research and development in dermatological treatments.

When handling Acitretin EP Impurity A (CAS: 69427-46-9), it is crucial to take appropriate safety measures. Always work in a well-ventilated area or fume hood to avoid inhalation of dust or vapors. Use gloves and safety goggles to protect your skin and eyes. It is also recommended to wear a lab coat and follow standard laboratory hygiene practices. Always consult the Safety Data Sheet (SDS) for detailed handling instructions and emergency procedures.
