Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its acyl fluoride group is highly reactive toward nucleophiles, making it valuable for forming amide and ester bonds under mild conditions. Commonly employed in the synthesis of liquid crystals and functional materials due to the stability imparted by the tert-butylphenyl moiety. Also utilized in Friedel-Crafts acylation reactions where a bulky aromatic acyl group is required. Its volatility and reactivity make it suitable for use in controlled reactions under anhydrous conditions.
