Product Description
4 methoxybenzoyl chloride (CAS No.: 100-07-2) is an important anisic acid chemical intermediate widely used in pharmaceutical synthesis and organic reactions. It is typically applied in acylation processes and the preparation of fine chemical derivatives. As a highly reactive acylating agent, this compound serves as a key building block in medicinal chemistry research. It has been documented in the synthesis of stilbene and dihydrostilbene derivatives studied as potential anti-cancer agents, as well as in the preparation of coumarin dimers investigated for potential HIV-1 inhibitory activity. These research applications reflect its value as a versatile electrophilic reagent in advanced organic synthesis.
Applications
• Pharmaceutical intermediate synthesis, including active pharmaceutical ingredient (API) precursors
• Synthesis of stilbene and dihydrostilbene derivatives as potential anti-cancer agents
