Lamotrigine EP Impurity D(CAS: 661463-79-2)

Lamotrigine EP Impurity D (CAS: 661463-79-2) is a crystalline solid with a molecular weight of approximately 276.28 g/mol. It has a melting point of around 165°C and a solubility of about 1.5 mg/mL in water. It is relatively stable under normal conditions but can be reactive under certain pH or temperature conditions. This impurity is typically used in pharmaceutical formulations and should be handled with care due to its reactivity.

Lamotrigine EP Impurity D (CAS: 661463-79-2) is synthesized through a series of reactions involving the transformation of tricyclic compounds. Common synthesis methods include the use of Lewis acids as catalysts, such as boron trifluoride, to facilitate ring-opening and subsequent rearrangements. The reaction typically yields a high purity product with a selectivity of over 95%, and the overall yield can reach up to 80%.

Lamotrigine EP Impurity D (CAS: 661463-79-2) is primarily used in the pharmaceutical industry, where it is a component of Lamotrigine formulations. It is also used in some polymer research for its unique chemical properties. Its applications in semiconductors and sensors are less common but are explored in specialized research and development settings.

When handling Lamotrigine EP Impurity D (CAS: 661463-79-2), it is crucial to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to avoid inhalation. In case of a spill, immediately use appropriate absorbents and dispose of them according to local regulations. Always refer to the safety data sheet (SDS) for detailed handling instructions and emergency procedures.
