Methyl 3,5-Dimethoxybenzoate

It is specifically used to prepare 5,7-dimethoxy-4-methylphthalide, a key intermediate in a multi-step synthetic pathway (typically five steps) to produce this immunosuppressive agent. Methyl 3,5-Dimethoxybenzoate is a crucial starting reagent used in the chemical synthesis of mycophenolic acid and its analogues.
