2-benzoyl benzoic acid

2-Benzoylbenzoic acid (also known as o-Benzoylbenzoic acid or O-BBA)

Applications

2-Benzoylbenzoic acid is a very important chemical intermediate with diverse applications, primarily in the dyestuff, pharmaceutical, and polymer industries.3 Key applications include:

Key applications include:

1. Dyestuff Intermediate

This is one of its major applications. It is a crucial precursor in the synthesis of anthraquinone dyes. Anthraquinones are a large class of highly stable dyes and pigments known for their excellent fastness properties (resistance to fading from light, washing, etc.), used extensively in textiles, paints, and inks.

2. Photoinitiator for UV Curing

It can be used as a photoinitiator in UV-curable coatings, inks, and adhesives. When exposed to UV light, it generates free radicals that initiate the polymerization (curing) process.

3. Pharmaceutical Intermediate

It serves as a building block in the synthesis of certain pharmaceutical compounds. Its derivatives have been explored for various biological activities.

4. Corrosion Inhibitor

It can be used as a component in formulations designed to inhibit corrosion in various systems.

5. Polymer Additive

It can be used as an additive in certain polymer formulations to impart specific properties.

6. Organic Synthesis

As a versatile aromatic carboxylic acid and ketone, it is a valuable reagent in general organic synthesis for the construction of more complex organic molecules. Its structure allows for various reactions, including cyclization to form anthraquinones.
