Homophthalic Anhydride | 703-59-3

Description :

Overview of Homophthalic Anhydride

Homophthalic Anhydride is an aromatic cyclic anhydride used as a key intermediate in pharmaceutical, agrochemical, and fine chemical synthesis. Structurally related to phthalic anhydride derivatives, it contains an additional methylene group in the aromatic ring system, providing unique reactivity in condensation and cyclisation reactions.

It is widely used in the synthesis of heterocyclic compounds, APIs, and speciality chemicals, and plays a crucial role in multi-step chemical reactions where a stable anhydride functionality is required. Homophthalic Anhydride is strictly an industrial chemical, not intended for food, fragrance, or cosmetic use.

Application of Homophthalic Anhydride

Pharmaceutical & Chemical Intermediate Applications

Homophthalic Anhydride is used as a reactive intermediate in pharmaceutical synthesis, particularly in the preparation of heterocyclic and nitrogen-containing molecules.
It participates in cyclisation and condensation reactions required for advanced intermediates.
It is commonly processed alongside Homophthalic Acid, Phthalimide, and N-Methylphthalimide in multi-step synthetic routes.

Agrochemical & Speciality Chemical Applications

Used in the synthesis of agrochemical intermediates, including herbicides and pesticide-related compounds.
