2-(4-Chlorobenzoyl)benzoic acid

2-(4-Chlorobenzoyl)benzoic acid (also known as o-(p-Chlorobenzoyl)benzoic acid or CBBA)

Applications

2-(4-Chlorobenzoyl)benzoic acid is a vital industrial fine chemical raw material and chemical intermediate with significant applications primarily in the pharmaceutical and resins & polymer industries, as well as in the production of dyes and pigments. Key applications include

1. Pharmaceutical Intermediates

It is a crucial starting material in the synthesis of important Active Pharmaceutical Ingredients (APIs).

Notably, it is a key raw material for the production of Chlorthalidone, a diuretic and antihypertensive drug used to treat high blood pressure and fluid retention.

It has also been mentioned as an intermediate in the synthesis of Mazindol, an appetite suppressant.

Its derivatives and related compounds are explored in various pharmaceutical research and development efforts.

2. Resins & Polymer Industry

It is used in the preparation of bisphthalazinone monomers. These monomers are essential for the synthesis of phthalazinone-containing poly(arylene ether)s, poly(arylene thioether)s, and poly(arylene sulfone)s. These polymers are high-performance materials used in various demanding applications due to their excellent thermal and mechanical properties.

3. Dye and Pigment Intermediates

It finds application in the production of specific dyes and pigments, particularly those used in textiles and coatings. The demand in this segment is driven by the textile, coating, and printing industries.

4. Research & Development

Used in academic and industrial research for organic synthesis, complex compound formation, and exploring new material properties.8 For example, it has been studied for forming complexes with lanthanides (like europium and terbium) that exhibit photoluminescence properties.
