Mertansine(CAS: 139504-50-0)

Mertansine is a crystalline compound with a molecular weight of approximately 332.36 g/mol. It is poorly soluble in water but soluble in organic solvents like DMSO. Mertansine reacts readily with nucleophiles and is often used in conjugation reactions. It has a pKa value of about 7.5 and a melting point around 180°C.

Mertansine is synthesized through a multistep process involving key reactions such as amination and conjugation. Commonly, it is synthesized from 4-hydroxy-3-methoxystyrene using coupling agents like HATU in the presence of a base. The reaction typically yields 80-90% purity, with careful control of reaction conditions to ensure high selectivity and yield.

Mertansine finds applications primarily in the pharmaceutical industry, where it is used as a precursor for anticancer drugs. It is also used in the development of imaging agents for diagnostics. Its properties make it valuable for research in areas such as drug discovery and biomedical imaging.

When handling Mertansine, it is important to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. Work should be conducted in a well-ventilated fume hood. Spills should be neutralized with an appropriate base and cleaned up carefully. Always refer to the Safety Data Sheet (SDS) for specific handling guidelines and emergency procedures.
