yellow crystalline powder

The Uses of 2-Hydroxybenzophenone

2-Hydroxybenzophenone was used to quantify the metabolites of unmethylated extracts from the supernatants of Pseudomonas acidovorans cultures grown on 1,1-diphenylethylene.

The Uses of 2-Hydroxybenzophenone

UV absorber in plastics.

Preparation

Preparation by Friedel–Crafts acylation of benzene in the presence of aluminium chloride,
? with 2-hydroxybenzoyl chloride (salicylic acid chloride), (52%), (39%), at temperature <60°;
? with o-anisoyl chloride. Demethylation occurred during the Friedel–Crafts acylation, especially in the presence of ferric chloride at 130–140°;
? with 2-ethoxybenzoyl chloride in a boiling water bath (42%).

What are the applications of Application
