Pemetrexed(CAS: 137281-23-3)

Pemetrexed is a white to off-white crystalline powder with a molecular weight of approximately 379.88 g/mol. It is poorly soluble in water but soluble in ethanol and acetonitrile. It is highly reactive towards metal ions and susceptible to hydrolysis under acidic or basic conditions.

Pemetrexed is typically synthesized via a multi-step process involving nucleophilic substitution reactions. The key step involves the coupling of a 5,4′-diaminopurine with a 4-aminolevulinic acid derivative. This process often requires the use of catalytic amounts of a tertiary amine and metal catalysts like palladium to achieve high selectivity and yield.

Pemetrexed is primarily used in the pharmaceutical industry, specifically for the treatment of cancer. It is also of interest in the development of new drugs and as a precursor in the synthesis of other bioactive compounds. Limited applications exist in the polymer and chemical industries for research purposes.

Pemetrexed should be handled in a well-ventilated area with the use of personal protective equipment (PPE), including gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from oxidizers and strong acids. In case of a spill, it should be handled according to the Material Safety Data Sheet (MSDS) guidelines, and the area should be well-ventilated. Handling should be done in a fume hood to minimize exposure.
